1. Burn Different Types Solid Fuels

The temperature in furnace is 850℃～950℃, the fuel particle could reach to furnace temperature and burn rapaidly. Thus, CFB boiler could burn different type solid fuels without any auxiliary fuels.

2. High Combustion Efficiency

the fuel is mixed with a large amount of high temperature bed fuels and burn rapidly, and has high combustion rate. The unburned particles are returned to furnace for circulating cumbustion by cyclone separator, lengthen combustion period, and increase co

3. Excellent Desulfurization Effect

Desulfurization process is processed under the optimum reation temperature in furnace, and the circulating system could lengthen the residence time of desulfurizer in boiler, also, the desulfurizer particle size is small as 0.1mm, the reaction contact are

4. Low NOx Emission

The furnace temperature is keep at 850℃～950℃, the temperature is relatively low, so the NOx emission is less. Otherwise, CFB boiler adopts zoning air supply and zoning combustion, the fuel could burn sufficiently, low NOx emission.

5. High Heat Load of Furnace Cross Section

Strong mixing and fast heat transfer in furnace, the furnace cross section has high heat load (around 3～5MW/㎡).

6. Slag Could be Utilizated comprehensively

The fuel is combusted under low temperature, and the high combustion efficiency makes slag has low carbon content, also, there are large amount of calcium oxide and calcium sulfate, could used for cement and brick, etc.
