火电厂烟气脱硫系统运行常见故障分析

Commonly Seen Failure Analysis of Thermal Power Plant Flue Gas Desulfurization System

为降低火电厂SO2的排放,大部分火电厂采用烟气脱硫技术,在烟气脱硫技术中湿式石灰石/石膏法脱硫应用最为广泛,而脱硫系统的运行可靠性是保证火电厂烟气脱硫效果,减少SO2排放的重要保证。在已投运的火电厂中,脱硫系统运行可能会出现脱硫效率下降,系统堵塞等问题,因此在实际过程中如何处理好此类问题成为保证火电厂脱硫效果的关键。

To reduce SO2 emissions from the thermal power plant,flue gas desulfurization technology is adopted in most of the plants,in which wet limestone / gypsum FGD is widely used,while the reliable and stable running of desulfurization system can ensure flue gas desulfurization effect and reduce SO2 emissions.Some problems may occur,such as,reduction of desulfurization efficiency and blockage,so in the actual process,how to handle such problems may be the key to ensure desulfurization effects.
