What are the advantages of the CFB boilers?

1、Wide fuel adaptability

① A large amount of combustible bed materials in the furnace

② Strong combustion and high circulation combustion efficiency

2、High combustion efficiency

① Fast combustion

② Extend the residence time of fuel in the furnace so that it can be fully burned.

3、High desulfurization efficiency

① Suitable temperature of desulfurization

② Enough residence time of coal

4、Low NOx emission

① Staged combustion

② Low-temperature combustion

5、High heat load — upgrade into large-capacity boilers

① High gas velocity in the furnace

② Strong mixing and fast heat transfer

6、Large load adjustment range, fast adjustment rate

① Adjust the coal feed rate and fluidization speed

② Change the circulation amount into the external heat exchanger
