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 clients 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.

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 or more fuels at the same time. Combustion air is divided into “primary” and “secondary” flows resulting in stratified combustion.

Natural gas firing

NOx 140 – 150 mg/Nm3
CO 30 mg/Nm3

Heavy fuel oil firing (N content 0,2 % by weight)

NOx 400 mg/Nm3
CO 100 mg/Nm3
Particulate 50 mg/Nm3

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.

Technical data

Firing rate up to 60 MW
Flame dimensions(*) adjustable
Materials carbon steel

stainless steel

Combustion air up to 550 °C
Turndown 7:1

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 or more fuels at the same time. These are our classic burners and we have a large number of references around the world.

Technical Data

Firing rate up to 60 MW
Flame dimensions(*) adjustable
Materials carbon steel

stainless steel

Combustion air up to 550 °C
Turndown 6:1
Pressure drop 150 – 200 mm wg

Natural gas firing

Particulate 50 mg/Nm3

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).

Technical Data

Firing rate up to 15 MW per row
Flame dimensions(*) 1.500 mm
Materials carbon steel

stainless steel

Combustion air up to 550 °C
Turndown 10:1
Pressure drop 10 – 20 mm wg

Natural gas firing with fresh air

NOx 30 mg/Nm3
CO 30 mg/Nm3

Natural gas firing with gas turbine exhaust

NOx – mg/Nm3
CO – mg/Nm3

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.

Technical Data

Firing rate up to 25 MW
Flame dimensions(*) adjustable
Materials carbon steel

stainless steel

Combustion air up to 400 °C
Turndown 5:1
Pressure drop 50 – 100 mm H2O

Natural gas firing

NOx 200 mg/Nm3
CO 50 mg/Nm3

Heavy fuel oil firing (N content 0,2 % by weight)

NOx 450 mg/Nm3
CO 100 mg/Nm3
Particulate 50 mg/Nm3

6. Off Gas and Low LHV Burners

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

Sometimes,s 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.
