Popis:	Wet flue gas desulfurization technology by using limestone gypsum has following advantages such as excellent adaptability for changes of coal and unit load, high desulfurizing efficiency, cheap absorbent, high reliability, and using less energy. So it's widely used in our country. This paper introduces the glue gas desulfurization process, network structure, main analog variable control system, sequence control system, interlock protection of distribute control system, industry television system and continuous emission monitoring system for Nengxin 200 MW thermal power plant in Henan. This desulfurization project has past environmental acceptance check and the guarantee period. Its desulfurizing efficiency exceeds 95 percent.
