We offer natural circulation boiler with Pusher-grate. This Biomass boiler is designed to combust variety of feed e.g. woodchips (virgin wood/waste wood), rice husk, agro-waste (briquettes/pellets) etc. at high efficiency. Thermal energy released from combustion process shall be used to generate superheated/saturated steam. This steam shall either produce electric power using steam turbine and generator set or shall be used in process (in case of process steam boiler). Part of the generated electricity will be consumed within the Plant and the surplus electricity will be exported to the electricity grid. The flue gas generated from the combustion process is treated in the flue gas cleaning system. The cleaned flue gas is then discharged via induced draft fan to the stack into the atmosphere. Our Biomass Power Generation plant shall mainly comprise of sub-systems as: Fuel feeding, Furnace system, Boiler, Flue gas treatment, water supply, wastewater handling, steam turbine, air supply ash handling etc.
More flexible for handling large particle fuel with a wide range of fluctuations on a pusher-type grate. Our solution entails low cost of fuel preparation as well as low auxiliary power consumption.
The grate system consists of parallel tracks. To achieve uniform combustion over the entire grate surface, the speed of the grate lanes is controlled simultaneously.
The hydraulic system works on signals from the process control system. The selection of the motion speed is done by preselected parameters according to the fuel characteristics
The primary air is supplied from below the grate – divided into several separately controllable zones and better secondary combustion due to high turbulence with proven combustion control system
The steam generator is designed as a vertical, water tube, single drum boiler. The arrangement for the superheaters allow for operation with minimum risk of chlorine corrosion
The entire boiler shell is supported in the boiler steel frame. The bearing of the steam generator allows for free expansion upwards and sideways in all operating conditions.
Large furnace volume with 2nd empty pass ensures complete combustion and minimizes fouling in superheater zone.
