湿法烟气脱硫系统特殊运行方式

2008年“5．12”特大地震,四川巴蜀江油发电厂2×330MW机组烟囱受损,使灾后恢复生产困难巨大。面对全省灾后用电的需求,既确保机组正常发电又不影响受损烟囱修复,是急需解决的突出问题。通过计算和调研论证,利用脱硫系统的特殊运行方式与搭建临时烟道相结合的方案,较好地解决了这一问题,使巴蜀江油发电厂灾后顺利恢复发电。

Particular Operating Mode of Wet Flue Gas Desulfurization System

The stack of the two 330MW generation units in Sichan Bashu Jiangyou Thermal Power Plant was broken due to the powerful earthquake on 12th of May, 2008, so it was a great difficulty to recovery the generation. Facing the electricity demands for the reconstruction in Sichuan Province, the outstanding urgent problem was to generate surely and to repair the stack at the same time. Based on the calculation and the experiences of other plants, the technical scheme was defined. In accordance with the technical scheme, the equipment for wet flue gas desulfurization （WFGD） was running in a particular form and the temporary flueway was being constructed. In this way, the problem had been solved felicitously, and therefore the power plant has been put into operation again successfully.
