Abstract

See full text

An integrated comprehensive adjustment method for a pulverized coal boiler based on high-temperature corrosion prevention and control of water wall is provided. The method includes: during shutdown period of the boiler, mounting reducing atmosphere sampling pipe on a water-cooled wall region; carrying out a diagnostic test on the boiler; carrying out an optimization and adjustment test of a boiler pulverizing system; carrying out a single-factor adjustment test of boiler-related parameters; determining degrees of influence of different parameters on water wall reducing atmosphere, thermal efficiency of the boiler and NOx concentration at a denitration inlet; carrying out an optimization test of ammonia spraying of a denitration system; carrying out a maximum safe denitration efficiency test; and finding a balance point among the water wall reducing atmosphere, the thermal efficiency of the boiler and the NOx concentration at the denitration inlet.
