Circulating Fluidized Bed is a new type clean burning technology with high efficiency, low pollution. The main characteristics is the furnace contains lots of fuel, these fuel can be carried to the upper furnace during the process of combustion, the flue gas and solid fuel were separated at the furnace exit, then the solid fuel will be re-burned after the revert. Which makes the fuel in multiple circulating combustion.
Due to the high concentration of the fuel, large capacity heat mix with the fuel (generally per kg flue gas can carry few kg fuel) these circulated fuel carry high heat coefficient, which makes the boiler with large load regulation and widely fuel adaptability.
Technical Advantages
1. High Efficiency
Combustion efficiency can reach to 98%, boiler thermal efficiency higher than 88-89%.
2. Lower pollution
Furnace desulfurization treatment can be carried out by adding the limestone, desulfurization efficiency can reach to more than 90%, lower temperature combustion make lower NOx.
3. Widely Fuel adaptability
4. Both the bituminous coal, anthracite coal, lean coal, lignite coal, high moisture biomass, even the furnace slag can be used in CFB.
5. The ash the slag can be comprehensive utilized.
6. the ash and slag can be recycled because the completely combustion.
7. Stable and reliable performance, lower failure rate.
