600MW supercritical W flame boiler water pressure test system improvement

Abstract

Abstract:

The practice that use air preheater high pressure wash pump as boiler primary system hydraulic test boost pump was introduced. The water source, pipeline and control system was improved. The improvement of existed boiler primary system hydraulic test system was realized. The problems of long time consumption, complicated operation, high tests cost and maintenance delay was avoided.

Key words:

supercritical, W flame boiler, air preheater, high pressure flushing water pump, water pressure test
