Overview
Overview
GB S is General Bruciatori’s fixed flame Duoblock burner family. The burner body is separate from the combustion air fan, giving great flexibility in layout and making it easier to adapt the system to existing boiler rooms or restricted spaces. GB S is designed for continuous duty on industrial boilers and process plants where a strong, simple and reliable burner is required.
Capacity range
The GB S Duoblock series covers a capacity range from approximately 0.2 MW up to 25.5 MW. This allows the GB S platform to be used on both medium and large boilers and process heaters.
Fuel flexibility
As part of the GB industrial burner platform, GB S is fully customizable for a wide portfolio of fuels, including:
- Natural gas and LPG
- Diesel and light oil
- Heavy fuel oil
- Biogas and other process gases (refinery gas, coal gas, waste gas)
- Certain waste and residual oils, animal fats and vegetable oils when engineered accordingly
Multi-fuel and dual fuel configurations are available on request, including simultaneous firing of different fuels under controlled conditions, for example natural gas plus biogas, or gas plus oil backup.
Key technical features
- Powder coated steel or aluminium body for robustness and long life
- Duoblock construction with separate fan for flexible layout and longer air ducts
- Heavy duty steel combustion head designed for high thermal and mechanical stress
- Dedicated combustion heads and disks per fuel type for stable flame and complete mixing
- Low NOx combustion heads available across the range
- Pilot burner system for smooth and safe ignition
- Large inspection window and easy access for maintenance
- No plastic parts in hot or stressed areas, suitable for heavy industrial operation
Options and customization
- EM versions with electronic control box and full modulation
- Integration with O2 and CO trim for efficiency and emissions
- Inverter driven combustion air fan
- Control panels supplied loose or mounted on the burner assembly
- ATEX and explosion proof executions
- Custom flanges, insertion lengths and connections to match existing doors and chambers
GB S brings together the simplicity of a fixed flame Duoblock burner with the full customization capability of the GB industrial platform.
Typical applications
- Steam, hot water and super heated boilers in industrial plants
- Thermal oil boilers for process heating
- Drying ovens and process air heaters
- Asphalt and aggregate dryers
- Kilns and furnaces where a fixed flame layout is appropriate
- Retrofit projects replacing older Duoblock burners while keeping the existing boiler
