Abstract :
Turbulence CFB(Circulating Fluidized Bed) dry desulfurization technology has advantages such as low investment and operation cost, high desulfurizing efficiency, small land occupation, and without wastewater. So it is suitable for desulfurization remodification of old power plant. This paper introduces the flue gas desulfurization process, network structure, analog variable control system, sequence control system and interlock protection of programmable logic control system for Pingshi power plant in Shaoguan. This desulfurization project has been completed and past the guarantee period. Its desulfurizing efficiency exceeds 85 percent.
