Fluidized Over Feed System (FOFS) Fluidized Pneumatic over Feed System (FPFS)
Effectively designed packaged boiler. Fuel can be fed automatically through a fuel feeding nozzle to produce 4000 Kg/ Hr steam at 150 Psi for process heating purpose.
Modernize method of fluidized combustion over nozzle arrangement takes place at furnace.
Capability of firing any kind of fibrous fuel makes the model demanding for all small process industry like Rice mill, Textiles, Food process, Pharmaceuticals & drug etc.
The fuel is fed from top of the boiler through a fuel feeding Nozzle arrangement and spreading cone method.
The boilers supplied are “3 Pass” Pneumatic system tube type package boiler. Each boiler would consist of combustion chamber with reversing chamber.
The fuel gas turns in the reversing chamber in to the second pass tubes enter the front smoke box.
The flue gas turns again in to chimney. The combustion chamber, the second pass and third pass tubes fully surrounded by water and thus provide a safe heat transfer area.
The Fuel is fired using unique designed air nozzles with sufficient pressure drop to burn the fuel in suspection.
Spreading cone enables uniform distribution of fuel above the nozzles.
Boiler is supplied with safety control devices like Automatic water level Controller (Mobrey) and Steam pressure switch.
In the pneumatic over feed (FPFS) boiler, the fuel is fed from the top of the boiler through a fuel feeding nozzle and spreading cone arrangement.
The fuel is fired on specially designed grate bars to burn the fuel in suspension under sufficient pressure.
Fuels like husk, G N shell, wood, and coal can be fired.
