Circulating fluidized bed process

Circulating fluidized bed process Circulating fluidized bed (abbreviation) desulfurization is currently widely used. The desulfurization and denitrification process combines process desulfurization with selective catalytic reduction denitrification. It is still in the development process. The innovation of the process is that it is based on the principle of circulating fluidized bed, which recirculates the absorbent multiple times in the reactor, extending the contact time between the absorbent and the flue gas, thus greatly improving the utilization rate of the absorbent.
The process has the following advantages
High agent utilization rate.
Low cost
Waste water generation.
Disadvantages
The comprehensive utilization of the mixture of unreacted and fly ash is subject to certain restrictions. The resistance of the fluidized bed flue gas desulfurization system is large. The residence time of the flue gas passing through the circulating fluidized bed at one time is short, and the operation The stability is not very good.
