石灰石湿法烟气脱硫运行可靠性的探讨

Discussion of the Reliability of Limestone Plaster Wet Flue Gas Desulphurization

阐述了影响石灰石-石膏湿法烟气脱硫率和投运率的主要因素,分析了排放量与脱硫率、投运率的关系。在总结电厂脱硫系统实际运行情况的基础上,对脱硫率的控制、GGH压差控制、旁路烟道挡板开关的操作以及一些其他易发生的问题进行了分析,提出如何提高脱硫系统的可靠性,以确保投入率和脱硫率达到要求。

In this article, we set forth the main element, of which influenced the rate of Limestone - the plaster wet flue gas desulphurization and the rate of the operation, analyze the relationship between the discharge amount, the rate of desulphurization and operation. Base on the summarize of the practice operation of the desulphurization system in the power plant, we analyze the rate of desulphurization control, the differential pressure of GGH control, the operation of the by - pass rear pass lagging switch and some other questions, which are happened easily, and put forward that how to increase the reliability of the desulphurization system to ensure the rate of input and achieve the request.
