摘　　要：以某公司烟气脱硫系统烟气换热器(GGH)为研究对象,分析了GGH堵塞对脱硫系统的影响,采取了优化压缩空气吹灰系统、增设GGH蒸汽吹灰系统、优化吹灰方式、优化吹灰控制策略等措施,缓解了GGH堵塞,降低了GGH运行压差区间,保证烟气脱硫系统安全、可靠运行。The flue gas desulphurization system gas-gas heater( GGH) of a power company was researched. The influence of GGH blockage on the desulphurization system was analyzed. The pressure air soot blower system was optimized. The steam jet soot blower system was installed additionally for GGH. The soot blowing mode and the soot blower control strategy were optimized. Then the GGH blockage was mitigated,the GGH operation pressure drop was decreased,and the safe and reliable operation of the flue gas desulphurization system was ensured.
