40 T/H Bituminous Coal/Anthracite/Lignite Fired CFB Boiler

1. 40T/H bituminous coal/anthracite/lignite fired CFB boiler:  The boiler is a new kind mixed fuel boiler with high efficiency and low pollution, it adopts circulating fluidized bed combustion technology with wide range of many kinds of fuel, such as bituminous coal, anthracite, lignite and others with lower calorific value. Its combustion efficiency is as high as 95-99%, especially it can burn high sulfur-bearing fuel. By feeding limestone into the boiler, it can obviously reduce the discharge of sulfur dioxide and NOx, and reduce corrosion of sulfur on devices and pollution of flue gas. Ash residue is active enough to be used as aggregate of materials such as cement. 2. 40T/H bituminous coal/anthracite/lignite fired CFB boiler arrangement: The boiler is a natural circulating water-tube boiler and adopts circulating combustion system formed by vortex cyclone separator. Its furnace is of membrane wall structure, its separator is of high-temperature adiabatic type. The sup…
