Multi Fuel Water Tube Boilers

Water tube high pressure steam boilers capacity upto 150 tph for process industry and also for power co-generation pressure up to 105 kg/cm2 and superheater temperature upto 540°C based on multi fuel bagasse, husk, agrowaste, palm seeds, coal on furnace grates like chain grate stocker, dumping/pulsating grate, FBC/AFBC etc. Design of Furnace volume & arrangement water wall tubes gives more heating surface in radiant zone to achieve maximum heat & complete combustion also avoid carry-over blockage in S. H. Zone. Variety of fuels & their combustion can be used. (Example : Bio Gas & bagasse also Wood, Coal, Rice-husk etc., can be effectively burnet individually & in combination )keeping the steam raising cost low. Fuel burns in suspension resulting in complete combustion. Arrangement for quick removal of ash without stopping the boiler provided so that the rate of the evaporation or working pressure do not stop. Provision of attemperation controls temperature. BOILER TYPES :- 1) Solid Fuel Water Tube Boilers 2) Oil Gas Fired Boilers - D Shape
