LMB G-RE

These are blower burners, with gas-air mixing at the combustion head and continuous modulation. They are entirely automatic and supplied with controls for maximum safety.

They can be combined with any type of combustion chamber, whether in a vacuum or under pressure, within the operatin range envisaged.

The burners are supplied complete with a gas supply ramp. The gas ramp is selected after careful consultation of the diagram of pressure loss depending on the mains gas pressure, on the gas flow rate required by the utility and on the back-pressure in the combustion chamber.

All burner components are easy to inspect, without having to disconnect them form the gas supply.

 

Technical specifications

  • Sheet steel body complete with flange for connection to the generator.
  • High performance fan.
  • Air intlet with shutters for combustion air control.
  • Electronically controlled servo-controls for air and gas control.
  • Flame display indicator light.
  • Stainless steel nozzle and combustion head.
  • Gas ramp comprising the operating and control valve, an electronically-valve seal control.
  • Air pressure gauge to check the presence of combustion air.
  • Flame presence control via photocell.
  • Gas valve seal control.
  • Electronic control and command equipment.
  • Parameter control display.
  • Diagnostics and errors display.
  • Modulation control unit.
  • Easy maintenance and access to the combustion head, which can be removed.
