Abstract:

Watervapor system of heat recovery steam generator is far more complex than coal burning boiler. Domestic studies on chemical cleaning of heat recovery steam generator are still in exploring. It discusses the selecting principles of cleaning medium in chemical cleaning of heat recovery steam generator in operation. The cleaning characteristics of high, medium and low pressure system are analyzed to designs a combined cleaning proposal for multisystems. It efficiently shortens the cleaning duration, and put forward disposal approaches to deal with liquid waste according to the cleaning proposals.
