Dual Fuel Burners

RLGB-MS Series Raadman Burner

Raadman’s mechanical staging burners are made of high-quality electro-mechanical components that are simple to install and commission and have a firing range of 1000 to 6100 kW.

The butterfly valve and cam mechanism allow for “Staging” operation on the gas mode. To achieve the desired stages in this type of burner, one actuator opens the butterfly valve and damper.

This category of burners includes all mechanical components, burner head, flame tube, and cam mechanism, safety accessories, ignition devices, flame scanners, burner controllers such as Shokouh /Honeywell TMG or Siemens LFL, burner actuators, accessories of power system, ventilation motor, fan wheel, safety of Gas train includes filter, regulator, main and safety valves, pressure gauges, minimum pressure switch, leak test switch, and valve proving system for burners with a capacity of over than 1.2 MW (All according to BS-EN 676).

Light oil system includes separate motor for oil pump, pump with pressure regulating valve, double main solenoid valve and one safety solenoid valve in feeding line, pressure gauge in feeding line, two nozzles for two stage operation (All according to BS-EN 267).
