摘　　要：针对当前湿法烟气脱硫系统经济效益和脱硫效率存在的问题,通过对湿法烟气脱硫系统前加装烟气余热回收装置,使脱硫系统设计方面得到了改造,并分析了造成脱硫效率降低的几个主要因素,并通过优化其运行方式,使得脱硫系统既满足高脱硫率,也使脱硫装置的经济效益得到了显著提高。从现在投运的电厂可知,该优化方法是可行的。For the current economic problems and the desulfurization efficiency on Wet flue gas desulfurization systems, the desulfurization system design has been modified by installed the flue gas heat recovery unit before the system. Via analyzed several major factors of the resulting lower desulfurization efficiency, it can make the desulfurization system to meet the high desulfurization rate. The economic benefits of the desulfurization equipment has been improved significant- ly through optimizing its operation mode. From the operating power plant, we can see the optimization method is feasible.
