Product Range:

Industrial Burners:
Industrial Burners are the flagship products of BCE, and are generally supplied to industrial boiler manufacturers for steam and power generation, or directly to Client within combustion system revamping. We could adapt such products for a large number of operating conditions, as they are designed and manufactured on job-by-job basis. Industrial Burners can reach high firing rate and, at the same time, satisfy the most stringent restrictions on pollutant emissions.

BCE Industrial Burners are designed to comply to specific Client’s requirements. Our burners are capable to burn one ore more fuels at the same time and are designed for industrial applications, mainly for Oil&Gas, steam and power generation, chemical and petrochemical industries; BCE industrial burners are usually installed on steam boilers, heat recovery steam generators, heaters, furnaces and anywhere is necessary thermal power for any kind of process.

1. Low NOx Burners DMPJE

Low NOx burners DMPJE are equipped with two air registers suitable for any kind of liquid and/or gaseous fuel with the possibility to fire one ore more fuels at the same time. Combustion air is divided into “primary” and “secondary” flows resulting in stratified combustion. This solution allow a general reduction of combustion temperature and therefore lowers thermal NOx generation.

They are provided with a series of gas lances made from stainless steel which can be adjusted during the operation. These lances injected the larger part of fuel gas; a small quantity is injected trough a central gas gun to ensure the flame stability.

When is requested a mixed gas/oil applications, a liquid atomizer replaces the central gas gun.

Air vorticity is generated and guaranteed by the vanes which formed each air register. The position of such vanes is set during the start – up phases and is important to control the flame intensity and shape which are different from one combustion chamber to another or from one fuel to another.

Fuel gas is distributed through an external plenum and a series on gas lances each of which is provided with a skew faced “multi jets” nozzle which can be adjusted and rotated to optimise gas distribution without halting burner operation.

Low NOx burners DMPJE are designed to meet low NOx requirements while providing high combustion efficiency and extreme versatility.

Typical applications of these type burners includes forced or balanced draft boilers as well as any kind of refinery or industrial furnace, thermal oxidizers and process heaters.

2.  Ultra Low NOx Burners DTPJE

Ultra Low NOx burners DTPJE are designed to satisfy the most stringent restrictions on pollutant emissions on fuel gas firing, with or without Flue Gas Recirculation (FGR) while providing high combustion efficiency and reliability with all kinds of gaseous fuels.

Thermal NOx reduction is achieved by separating both the combustion air and the fuel gas in “primary” and “secondary” flows which ensures a “staged” combustion with less “hot spots” where NOx formation would be critical.

Typical applications of our Ultra Low NOx burners includes forced or balance draft boilers as well as any kind of refinery or industrial furnace, thermal oxidizers and process heaters.

Two air registers control combustion air flow. Each register is consisting of an axially moving drum controlling primary / secondary air rations. Strong combustion air vorticity is achieved by means of primary and secondary air swirlers whose position is set during the start – up and commissioning phases to provide the proper air turbulence which ensures optimal mixing with the gas.

In order to provide Ultra Low NOx emissions, the fuel gas is distributed in a wide volume to provide high combustion efficiency while reducing overall flame intensity. Most of the fuel gas is injected through a fuel gas distribution plenum equipped with a set of lances. Each lance is provide with a “multi jets” nozzle which injects the fuel gas outside the refractory throat. The nozzles can be rotated without halting burner operation to optimise gas distribution, achieving low emissions and combustion efficiency.

An additional central gas lance is fed with a small portion of the fuel gas, ensuring very high flame stability over very wide burner firing ranges.

3. Low NOx Burners MPJE 

Low NOx Burners MPJE are equipped with one air register suitable for any kind of liquid and/or gaseous fuel with the possibility to fire one ore more fuels at the same time. These are our classic burners and we have a large number of references around the world.

They are provided with a series of gas lances made from stainless steel which can be adjusted during the operation. These lances injected the whole or larger part of fuel gas with the possibility to install a central gas lance which injected the remainder part. This solution ensure a better flame stability.

Combustion air reaches burner throat thank to air register which can be manual or automatic.

When is requested a mixed gas/oil applications, a liquid atomizer replaces the central gas gun.

Air vorticity is generated and guaranteed by the vanes which formed the air register. The position of such vanes is set during the start – up phases and is important to control the flame intensity and shape which are different from one combustion chamber to another or from one fuel to another.

Fuel gas is distributed through an external plenum and a series on gas lances each of which is provided with a skew faced “multi jets” nozzle which can be adjusted and rotated to optimise gas distribution without halting burner operation.

Low NOx Burners MPJE are designed to meet classic emissions requirements and reach the compromise between cost and performance while providing high combustion efficiency and extreme versatility.

Typical applications of these type burners includes forced or balanced draft boilers as well as any kind of refinery or industrial furnace, thermal oxidizers and process heaters.

4. Duct burners

Duct Burners are usually used in combined cycle and they can work either with fresh air (when gas turbine is turned off) or exhaust gas. For this reason they are made from stainless steel in order to resist to the high temperature inside the duct (up to 500 °C).

Critical conditions at the gas turbine discharge (gas flow rate, temperature, stream vorticity and duct lay – out) often require a CFD study, to provide the best solution and guarantee the best performance in terms of operating, maintenance and expected life of the combustion system.

Duct Burners are generally provided in several rows depending of the thermal power required and the general duct arrangement.

Each row is completely filled by stainless steel baffles, which have a modular design that ensure the mixing between gaseous fuel and flue gas or fresh air; such baffles are fixed on gas distributor by screwed nozzles also made from stainless steel.

Fuel gas is injected through a fuel gas distribution tube, equipped with a set of the above mentioned nozzles. Each “multi jets” nozzle injects the fuel gas inside the combustion chamber.

Each distributor is supported by a carbon steel front plate which is flanged to the duct wall. The front plate has also the support for flame scanner and pilot igniter.

This system guarantee a wide turndown range (10 : 1 for each row) and low pollutants production. 

5. VRGO burners

BCE burners type “VRGO” are typically equipped with a series of gas lance and one central gas lance. If designed to burn heavy fuel oil or diesel oil, the central gas lance is replaced with fuel oil/diesel atomizer.

The “VRGO” burners are designed to reach high efficiency combustion level and can be supplied as part of new combustion systems as well as revamping of existing plants.

The typical supply is completed with combustion air wind box and combustion air isolating and balancing damper. In “VRGO” burner the air vorticity is guaranteed by a swirler made from stainless steel installed near the burner throat on an apposite tube.

The simple and compact design enable the use of these burners in a wide range of application and in particular they are largely use in small systems as heaters or preheaters or where is necessary a series of burners like in furnaces. 

6. Off Gas and Low LHV Burners

Some industrial processes produce synthesis and recovery gaseous streams which have, as main characteristics, high temperatures, low pressures and, most important, very low calorific values. BCE can design and supply Off Gas and Low LHV burners suitable to burn such gaseous streams, to recover the energy that otherwise would be lost.

These burners are supplied with external gas scroll, through which the gaseous stream is injected inside combustion chamber. Each burner is also supplied complete with gas lances and central gas gun, which are necessary to heat up the system before syngas injection.

Sometimes, when the calorific value is very low, the central gas gun or a continuous pilot is kept operational.

If there is the presence of two syngas streams which have very different characteristics in terms of volume and operating conditions, we could provide burners with double external gas scroll. 

Special burners:
Burners designed for particular application; they may be suitable for power generation as Off gas and low LHV burners, operating with gaseous streams at high temperature and low pressure or recovery gas coming from other processes or suitable for industrial applications where are necessary a good heat input as bath heaters or air heaters. Normally, these are designed on the basis of our classic burners.

BCE is also able to produce burners for completely different applications, where are normally used particular materials (i.e. Hastelloy), and where the burners must able to work in hard conditions, as blast furnaces or sulphur production plants.

1. Sulphur Burners

Sulphur is one of row materials used in sulphuic acid production plant or in plant where sulphur is necessary to generate other chemical products (for example aluminum fluoride). In these processes, the sulphur is burned inside a refractory furnace to produce its derivates.

BCE can supply this kind of burner complete with tip and plug for mechanical atomization of sulphur. For this reason is important that sulphur reaches the burner at high temperature and pressure and at liquid state. To guarantee the correct combustion conditions, the burner is traced by steam to maintain the temperature and avoid solidification.

Normally we supply also a natural gas/oil burner, which is necessary to heat-up the furnace and reach the correct operating conditions. Once reached the conditions, the burner’s central body is replaced by sulphur burner to initialize the process. 

2. Off Gas and Low LHV Burners

Some industrial processes produce synthesis and recovery gaseous streams which have, as main characteristics, high temperatures, low pressures and, most important, very low calorific values. BCE can design and supply Off Gas and Low LHV burners suitable to burn such gaseous streams, to recover the energy that otherwise would be lost.

These burners are supplied with external gas scroll, through which the gaseous stream is injected inside combustion chamber. Each burner is also supplied complete with gas lances and central gas gun, which are necessary to heat up the system before syngas injection.

Sometimes, when the calorific value is very low, the central gas gun or a continuous pilot is kept operational.

If there is the presence of two syngas streams which have very different characteristics in terms of volume and operating conditions, we could provide burners with double external gas scroll. 

3. Air Heaters – Incinerators – KILN Burners

BCE “KS” type burners are generally use in processes where are not required particular performance like restricted emission levels or high thermal power demand. Such processes could be air or gas heaters, incinerator or biomass boiler where they are used for start-up and heat-up of generator.

These burners are not provide with air wind box; combustion air comes from a distributor duct which is flanged directly to burner. There isn’t an air register but only a diffuser for air distribution.

BCE can also supply burners for “KILN” processes: these burners have similar design to “KS” burners but they can be adapted to KILN furnaces conditions. According to the system in object, KILN burners could have one, two or three combustion air distributor suitable for fresh or pre-heated combustion air. They are usually supplied complete with refractory throat and, if required, with isolated wind box.

KS and KILN burners can operate either with gas or fuel oil/diesel oil. 

4. Blast Furnances Burners

These kind of burners are suitable to operate in metallurgical processes where the operating temperatures are very high. In fact, our blast furnace burners are usually made from Inconel/Hastelloy, materials suitable to resist to severe working conditions.

These burners are usually equipped with a central pilot igniter operating with natural gas or rich gas, which ensures a correct combustion of the gaseous stream fired by burner. Burners are feeding by a low LHV gas coming from process (Coke Oven Gas or similar) and, when not in operation, they are cooled by a nitrogen stream.

No air register is installed in such burners; the burner is provided complete with a central swirler to guarantee a minimum combustion air vorticity.

We could also provide the supply of complete fuel gas skids and control system. 

Burner Management System:

BCE can provide complete solutions for the safe and efficient start – up, operation and shut – down of complete combustion systems for Water tube boilers, Heat Recovery Steam Generator (HRSG), Waste to energy incinerators, Waste liquid and gaseous streams incinerators and many other industrial applications.

The typical Burner Management and Control System is consisting of two separated units as per NFPA 85 “Boilers and Combustion Systems Hazards Code – Last Edition” requirements. Upon Client’s requirement simpler systems designed are also available.

BCE engineers develop all the engineering lay – out drawings, electrical schemes and software in house.

The Burner Management System ensure that burners start – up, shut – down and operation take place under safe and controlled conditions, acquiring signals from in field instrumentation and performing all trips related to safety. BCE can also provide the Control system which is also connected to field instrumentation and provides the continuous modulation of the burner firing rate, according to the requirements of Client’s process. A SCADA – Basic graphic interface is provided with the control system to ensure that Client’s personnel can easily operate and oversee the plant.

All the systems are designed to be linked in a control network using all main standard communication protocols (ModBus, Profibus, TCP/IP, etc.). BCE continued support ensures competent and adequate technical assistance to any Client everywhere in the world, following installation, commissioning, and start – up of the combustion system, and providing maintenance and spare parts to maximize the system’s lifetime.

The Burner Management System engineered by BCE are able to control and manage various combustion systems, with one or multi burners boiler which operate with one or multi fuels at the same time. The systems are usually based on Programmable Logic Circuit (PLC) complete with all necessary hardware and I/O modules, buttons and lamps for operator interface and visualization of alarms/trips from cabinet front.

We could provide as well to special systems based on timers and relays for particular application.

The Burner Management System is designed according to the Client’s specific requirements for Fail Safe PLC with single or redundant CPUs and power supply units. System architecture allows maximum modularity and ease of maintenance.

Each Burner Management System is supplied completely configured, cabled and wired to terminal strips in a free standing cabinet and tested (with Client witnessing if required) at our workshop by means of an I/O simulator.

All main PLC brands can be provided. In particular we usually supply:

  • HIMA
  • Siemens
  • Allen Bradley

TYPICAL BCE SUPPLY

  • Burner Management System completely assembled and tested at our workshop with issue of internal test certificate (if required, test could be witnessed)
  • BMS detailed lay-out drawing
  • BMS electrical schemes and I/O lists
  • Local panel (usually one for each burner) with push buttons and lamps wired and tested
  • Operating and maintenance manuals

Assembled Skids

Our company design and manufacture assembled skids for its combustion system or for existing system according to project design basis and to required codes. We provide gas and oil skids mechanically, electrically and pneumatically assembled until Client’s battery limits.

1. Assembled Oil Skids

BCE is able to provide engineering and/or complete supply of mechanically, electrically and pneumatically assembled skids. Typically we supply skids for heavy fuel oil/diesel oil and fuel gas feeding line to burners.

Each skid is normally designed according to the relevant Code & Standards for such equipment, i.e. ASME, PED, API, TEMA, ATEX and so on.

Fuel oil heating and pumping unit are necessary where fuel oil combustion is required. In such combustion system, fuel oil must reach the burners with a correct temperature (to reduce the viscosity) and correct pressure (to guarantee a stable atomization). This is what assembled oil skids are made for. Depending on combustion system power and relative design criteria (pressure limits, overdesign, available stream, redundant logics), we supply every items necessary to the correct operating of the system which skid is connected to.

Main items that take place on assembled oil skids can be inlet and outlet strainers, pumps with coupled electric motors, heat exchangers which could be electrical or feeding by medium or low pressure steam, fuel oil control and recirculation valve, steam control valve (if any), valves and instrumentation train for local/remote control and management, junction box cabled and wired, compressed instrument air distribution for pneumatic valves. Moreover is important to maintain in temperature the fuel oil line, in particular when the unit is not in operating, to avoid occlusions by cold oil and to guarantee the prompt availability when necessary; this could be made by electric tracing or steam tracing (with low pressure steam) around the piping and components.

We could provide equally to diesel oil skid supply, basing on the same Standard and Codes and design criteria. Such systems are simpler than previous because diesel oil is easier to treat; in fact the heating line is not necessary (electric or made by steam) as well as tracing and therefore the equipment installed are less than the other, if compared to the same power required. 

2.  Assembled Gas Skids

As described for heavy fuel oil and diesel oil, BCE is also able to provide engineering and/or complete supply of local and general assembled gas skids for any type of gaseous stream (natural gas, hydrogen, coke oven gas, nitrogen, oxygen, and so on).

The skid is supplied mechanically, electrically and pneumatically assembled and we could provide also a local control panel if necessary and, if requested, by type of application.

Feeding units to burner/s are typically complete with relevant instrumentation, manual and pneumatic valves, flow meter and control valve which regulates fuel flow rate basing on thermal power required from combustion process, both for gas and oil.

Regarding assembled gas skids we could also supply pressure reduction station which are necessary when fuel gas is provided at high pressure in front of fuel gas skid operating pressure (typically 3 barg).

BCE can also supply, before the final assembly, several test on piping i.e. pressure test, welding test (WPS/PQR, LP, PMI), painting test and issue to Client the relative certificates. 

Combustion Equipment
1. Pilot Ignitors

BCE produces a wide range of industrial electric pilot ignitors suitable for the light up of large industrial burners. The most powerful pilot ignitors are based on high – energy systems developed over decades of experience in applications requiring safe and reliable operation, such as power generation plants and steam generating utilities.

The High Energy ignition systems are insuring a number of robust intermittent sparks, realised by the energy accumulated by a capacitor, providing more powerful ignition capacity than high tension arc electrodes.

The HE series of BCE pilot ignitors includes gas electric ignitors, light oil electric ignitors, without or with premixed air, suitable for continuous operation, as well as the direct spark ignitor for light up of heavy oil.

Usually, pilot ignitors are an integral part of the supply of burners or combustion systems, but we can also provide the single pilot ignitor as a part of new combustion system as well as revamping of existing systems.

The pilot ignitors can be supplied with in-built flame scanners or ionisation flame rods, with automatic retraction drivers and with power supply units for installation in any environment and hazardous area.

High Energy Electric Ignitor is capable to withstanding to every temperature which could be present inside wind box (up to 350 °C), and the discharge head itself must withstand to the very high radiation and temperature close to the burner flame. The BCE unit is suitable for a maximum surface temperature of 750 °C at the discharge head.

The pilot ignitor consists of three main parts, namely:

  • Control Box, in which the power for the discharge is generated;
  • High Voltage Armoured Cable, used to carry this power to the ignitor itself;
  • The Special Ignitor End, at which the discharge occurs across a semi conductor gap.

We can provide pilot ignitors for a wide range of application and for any kind of industrial process, as industrial boilers for steam/power generation, which burners where installed on boilers front wall or at boilers corners (tangential combustion), refinery or industrial furnace, thermal oxidizers and process heaters and so on.

PILOT BURNER TYPE
Any pilot ignitor could be support flame detection, if required. Here below are listed our ignitor models:

  • HE 168 Is designed for intermittent use and is suitable for flame detection, if required. It’s normally used in the large part of our installation and where no particular characteristics are required.
  • HE 568 As for HE 168 this pilot is designed for intermittent use, it can accept flame detection and we can provide either explosion proof execution or a system suitable for safe area; the principal difference is that such system is premixed type, which is important to guarantee the flame stability in some cases.
  • Special We also provide a wide range of special ignitors different from our typical supply designed basing on Client’s specific requirements or for particular uses and plants where are required dimensions, materials or operating mode different from the above mentioned igniters.
  • HT 468 If required we could also provide High Tension Ignitor which is self—aspirated type and therefore premixed type. The ignition power is provided by an electrical arc between electrodes (there is only transformer inside the Control Box supplied).

  • Control box for safe or hazardous area complete with flame amplifier where required
  • High voltage armored cable
  • Flexible hoses for fuel gas / fuel oil to pilot igniter, premixing air where is required, cooling air
  • Flame detection system
  • Piping and instrumentations trains 

SNCR DeNOx Systems
Selective Non-Catalytic Reduction Systems (SNCR DeNOx Systems) are used to remove harmful nitrogen oxides from hot flue gases by reaction with Urea or Ammonia solutions injected inside combustion chamber outlet with balanced flow rates and dispositions and are used in power plants that burn biomass, coal or waste.

Is important to introduce the solution within temperature ranges of 900 – 1000 °C, in order to guarantee the best possible reaction and reduce at minimum the residual ammonia slip. Moreover, is important to choose the correct combustion chamber elevations where the lances will be installed, also for guarantee a proper permanence time.

Urea is easier to handle and less dangerous than ammonia; the principal reactions involved in the process are the following:

NH2CONH2 + H2O —> 2NH3 + CO

4NO+4NH3 + O2 —> 4N2 + 6H2O

BCE can supply complete SNCR DeNOx Systems designed to reach a good NOx reduction with NOx conversion up to 60 – 70%. As usual, our products are made on job by job basis, according to Client’s specific requirement, and therefore we could provide systems suitable both for small or big plants.

Usually, our SNCR DeNOx Systems are composed by the following items:

  • N° 1 skid which include recirculation pumps from/to solution tank, solution dosing pumps from tank to lances skid and demineralized water dosing pumps from utilities network to lances skid for correct atomization and lances cooling. The skid include all the necessary valves and instrumentation, basket filters, mixer and so on
  • N° 1 (or more if any) skid for solution distribution to lances complete with atomizing air feeding and all the necessary valves and instrumentation
  • N° 1 skid for cooling air distribution to lances usually composed by no. 2 blowers, valves and instrumentation
  • A set of injection lances designed for solution injection/atomization by compressed air with tip and plug

We can also provide to the supply of solution tank which include the necessary flanged connections for tanker loading, internal cleaning, vent and instrumentation, electrical resistance to avoid urea crystallization at low temperature (if any), support structures, ladders and platforms.

Each item will be designed and supply according to specific codes & standards.

BCE can also supply, before the final assembly, several test on piping i.e. pressure test, welding test (WPS/PQR, LP, PMI), painting test and issue to Client the relative certificates.

Finally, we can supply a cabinet suitable for DeNOx control and management complete with panel showing the signals comes from field, alarms and so on, push buttons for start-up/shut-down and lamps. Inside the cabinet will be located the necessary contactors, relays, power units and all the other components required to realize the correct control logics.

With the mechanical supply, we usually provide skids, tank and cabinet lay-out drawing, I/O lists, electrical schemes and cabinet schemes, valves and instrumentation, blowers and pumps datasheets, material certificates, quality control plan and operating and maintenance manuals.

Applications
The Company is present since the ’70 years in the most important industrial markets, in particular regarding the power generation in all of its forms, chemical, petrochemical and manufacturing industries. During these decades we have realized hundreds and hundreds industrial plants worldwide and installed thousands of thermal MW with our combustion systems together with appropriate safety and control systems, according to increasingly restrictive international Codes&Standards regarding pollutant emissions and safety. Our priority is to meet the needs of our Customers, and solve their problems and requests ensuring safety, efficiency and reliability.

In particular, we have developed our products for the following applications:

  • Steam generators for power generation, cogeneration and industrial processes
  • Heat Recovery Steam Generators of combined cycles
  • Waste to Energy system
  • Heaters and Furnaces for chemical and petrochemical processes

Steam Generators
A water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.

The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services (power generation), the steam will reenter the furnace through a superheater to become superheated. Superheated steam is a dry gas and therefore used to drive turbines to produce electric energy by generator.

A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.

Such boilers are usually used where are not requested high power and sometimes are preferred to water tube boiler thanks to their simpler configuration.

Steam boilers are the typical applications of our “M”, “DM” and “DT” burners type which are designed and offered according to the emission levels required and fuels to be burn.

  2. Ultra Low NOx Burners DPTJE
  3. Low NOx Burners MPJE
  4. Off Gas and Low LHV Burners 

Heat Recovery Steam Generators
A heat recovery steam generator or HRSG is an energy recovery heat exchanger that recovers heat from a hot gas stream, usually coming from gas turbine or engines. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle).

HRSGs consist of four major components: the economizer, evaporator, superheater and water preheater. The different components are put together to meet the operating requirements of the unit.

Modular HRSGs can be categorized by a number of ways such as direction of exhaust gases flow or number of pressure levels.

The HRSGs systems could be of two type: one, where gas turbine is coupled directly to the steam generator and the major components are disposed in line: superheater, evaporator and economizer (one pressure level); this is the typical application of our burners “DB” type, which are installed inside the duct that connects gas turbine and steam generator. The other type is a classic steam generator: the exhaust gas coming from gas turbine reaches the burners, which are installed on boiler front wall. This is the typical application of our burners “M” or “DM” type, adapted for such application.

In both cases the burner are suitable to work either with hot flue gas stream or fresh air.

Waste to Energy Systems
Waste-to-energy (WTE) is the process of generating energy in the form of electricity and/or heat from the incineration of waste. WTE is a form of energy recovery. Most WTE processes produce electricity and/or heat directly through combustion.

Incineration, the combustion of organic material such as waste with energy recovery, is the most common WTE implementation. The combustion of waste may produce many pollutants that must be treated and reduced before the stack, to avoid environmental contamination.

In such systems is necessary to have a combustion system properly designed: the role of the burner (or burners) is to heat up the furnace and the combustion chamber during the start-up phases until a temperature suitable for the introduction of waste and the maintenance of the flame stability by the same. Once the combustion chamber has reached the correct working temperature, the burner is moved in stand-by position and protected from the flame and flue acid gas generated by waste combustion. The burner will return in firing position only if the temperature in combustion chamber reaches the limits imposed by law, or to shut-down the incinerator.

Depending from incinerator’s characteristics and Client’s request we are able to design such combustion system complete with all ancillaries equipment (combustion air fan, oil & gas skids and so on) and control system. Usually, for the above application, we use “M” or “DM” burners type.
