Burners & combustion systems
Industrial burners are the flagship products of BCE — supplied to boiler manufacturers for steam and power generation, or directly to plant operators revamping their combustion systems.
Engineered job by job
Burners and combustion equipment are engineered for each project by a team of specialised engineers, so they can be adapted to a wide range of operating conditions. Industrial burners reach high firing rates while meeting stringent restrictions on pollutant emissions.
Each supply comes with detailed technical documentation for installation, and quality control plans secure project management, workmanship and material quality. Qualified engineers support installation supervision, commissioning and start-up.
Range
Industrial burners
DMPJE
Two air registers, for liquid and/or gaseous fuels — one or several fuels at the same time. Combustion air is split into primary and secondary flows for stratified combustion.
| Firing rate | up to 60 MW |
|---|---|
| Turndown | 6:1 |
| Combustion air | up to 550 °C |
| Pressure drop | 150 – 200 mm wg |
| NOx, natural gas | 140 – 150 mg/Nm³ |
| CO, natural gas | 30 mg/Nm³ |
| NOx, heavy fuel oil* | 400 mg/Nm³ |
| Particulate, heavy fuel oil* | 50 mg/Nm³ |
DTPJE
For the most stringent emission limits on gaseous fuels, with or without flue gas recirculation (FGR), at high combustion efficiency.
| Firing rate | up to 60 MW |
|---|---|
| Turndown | 7:1 |
| Combustion air | up to 550 °C |
| Pressure drop | 200 – 250 mm wg |
| NOx, natural gas without FGR | 75 mg/Nm³ |
| NOx, natural gas with FGR | 55 mg/Nm³ |
| CO, natural gas | 30 mg/Nm³ |
MPJE
The classic BCE design: one air register, for liquid and/or gaseous fuels, with a large number of references worldwide.
| Firing rate | up to 60 MW |
|---|---|
| Turndown | 6:1 |
| Combustion air | up to 550 °C |
| Pressure drop | 150 – 200 mm wg |
| NOx, natural gas | 200 mg/Nm³ |
| CO, natural gas | 30 mg/Nm³ |
| NOx, heavy fuel oil* | 450 mg/Nm³ |
| Particulate, heavy fuel oil* | 50 mg/Nm³ |
Duct
Typically used in combined-cycle plants, firing with fresh air (gas turbine off) or with turbine exhaust. Stainless steel construction for duct temperatures up to 500 °C.
| Firing rate | up to 15 MW per row |
|---|---|
| Turndown | 10:1 |
| Combustion air | up to 550 °C |
| Pressure drop | 10 – 20 mm wg |
| Flame length | 1,500 mm |
| NOx, natural gas, fresh air | 30 mg/Nm³ |
| CO, natural gas, fresh air | 30 mg/Nm³ |
VRGO
A series of gas lances plus a central lance, which is replaced by a fuel-oil or diesel atomiser for liquid firing. For new combustion systems and the revamping of existing plants.
| Firing rate | up to 25 MW |
|---|---|
| Turndown | 5:1 |
| Combustion air | up to 400 °C |
| Pressure drop | 50 – 100 mm H₂O |
| NOx, natural gas | 200 mg/Nm³ |
| CO, natural gas | 50 mg/Nm³ |
| NOx, heavy fuel oil* | 450 mg/Nm³ |
Off-gas
External gas scroll injects the process gas into the combustion chamber; gas lances and a central gas gun heat up the system before syngas injection. At very low calorific values the gas gun or a continuous pilot stays in operation; two syngas streams can be handled with a double external scroll.
Flame dimensions adjustable (except duct burners); materials carbon steel or stainless steel. *Heavy fuel oil with 0.2 % nitrogen by weight. Values as published by thenex for BCE burners; project-specific data on request.
Special burners
For sulphuric acid plants and other processes using sulphur as a raw material, such as aluminium fluoride production.
For process gases with low or variable calorific values.
Combustion air comes from a distributor duct flanged directly to the burner — no wind box, no air register, a diffuser instead.
For metallurgical processes at very high operating temperatures.
Burner management systems
BCE supplies complete burner management systems for water-tube boilers, heat recovery steam generators (HRSG), waste-to-energy incinerators, waste liquid and gas incinerators and many other industrial applications.
The typical control system consists of two separate units in line with NFPA 85 (Boiler and Combustion Systems Hazards Code); simpler systems are available on request. Each system is supplied fully configured, cabled and wired to terminal strips in a free-standing cabinet, and tested in the workshop with an I/O simulator — witnessed by the client if required. All main PLC brands can be provided, typically HIMA, Siemens and Allen-Bradley.
Assembled skids
thenex and BCE provide engineering and complete supply of mechanically, electrically and pneumatically assembled skids for heavy fuel oil, diesel oil and fuel gas feeding lines to burners.
