预防和治理大型发电机组脱硫设备的 GGH（空气换热器）结垢堵塞有效方法
The Effective Ways of Prevention and Management to Manage the Desulfurization Equipment GGH (Gas Gas Heater) Plug Fouling of Large Generating Units
摘要
Abstract
The original GGH heat exchanger of FGD desulph-urization equipment of a power generator group in the course of recurrent occur plug fouling, which make the GGH differe-ntial pressure increased, affect the effect of desulphurization. By using the online high-pressure water washing and compre-ssed air purge be able to reduce the differential pressure of the GGH, but aging equipment and use a long time, the ef ect is not very good, and the original chemical cleaning can effect-ively solve the dredge problem of the GGH heat exchanger fo-uling blockage.关键词
