Circulating fluidized bed flue gas desulfurization technology (RCFB-FGD) is advanced flue gas desulfurization technology by dry method according to principle of circulating fluidized bed.The technology is mainly used in power station boiler for flue gas desulfurization.
Technical features:
(1) High utilization of absorbent;
(2) Without rotatable parts and quick-wear parts in absorption tower;
(3)Desulfurizer and desulfuration residue are in dry state, thus no sticking, blocking and corrosion;
(4)High SO3 removal rate.
Advantages
High efficiency, simple gas desulfurization system, small floor area, low operation and maintenance cost, low energy consumption of auxiliary system, without wastewater discharge, low water consumption, and etc.
