Overview
GB ML is General Bruciatori’s industrial Monoblock burner series for steam, hot water, superheated water and thermal oil boilers, as well as a wide range of industrial furnaces and dryers. The compact body with integrated fan makes installation simple on both boilers and process heating equipment, while the mechanical design is robust enough for continuous industrial duty. GB ML is built as a modular platform that can be adapted and customized for many different types of plants and combustion chambers.
Capacity range
The GB ML Monoblock series covers a capacity range from approximately 1.5 MW up to 17 MW, allowing the same burner family to be used from medium industrial boilers up to large process plants.
Fuel flexibility
Like all GB industrial burners, the GB ML series is designed on a fully customizable fuel platform. Burners can be engineered to operate on:
- Natural gas and LPG
- Diesel and light oil
- Naphtha and other medium distillates
- Various process and waste gases when required
- Combinations of gas and oil in dual fuel or mixed firing mode
On request, GB ML burners can be configured as multi-fuel units including simultaneous firing of different fuels, for example natural gas plus LPG or a liquid backup fuel, depending on project requirements.
Key technical features
- Monoblock construction with integrated combustion air fan
- Powder coated steel or aluminium body for robustness and long life
- 2 stage progressive or fully modulating versions
- Mechanical cam or electronic cam modulation
- Compatibility with advanced combustion controllers such as O2 and CO trim
- Possibility to integrate inverter driven fan for lower electrical consumption and reduced noise
- No plastic parts in hot or stressed areas, suitable for heavy industrial operation
Options and customization
- Gas and oil trains designed according to local norms and customer specifications
- O2 trim and O2/CO trim systems for efficiency and emission control
- External 4-20 mA or BUS control signals for integration with plant automation
- Different flange and insertion lengths to match existing boiler doors
- IP55, IP65 and ATEX executions for specific environmental conditions
The GB ML series is the ideal Monoblock platform when a compact burner is required without sacrificing industrial performance, fuel flexibility and customization.
Typical applications
- Fire tube and water tube steam boilers in industrial plants
- Hot water and superheated water boilers for heating and process
- Thermal oil boilers for process heating
- Industrial furnaces and ovens for process heating and heat treatment
- Dryers and air heaters for industrial drying lines
- Biomass boilers where gas or oil firing is used as support or backup
- Retrofit projects where an existing Monoblock burner needs to be replaced by a higher performance, customized unit
