Abstract

The embodiment of the invention provides a slagging analysis method and device for a power station boiler. Boiler parameters and coal analysis data are obtained, the heat efficiency of the boiler are calculated according to the boiler parameters, the boiler slagging characteristic is obtained through calculation according to the coal analysis data and the heat efficiency, and the slagging degree is judged according to the boiler slagging characteristic. The technical problem that no complete analysis method for power station boiler slagging and characteristics exists at present, and consequently, how to analyze the power station boiler slagging becomes the issue is solved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for analyzing slagging of a power plant boiler. Background technique [0002] 2 sets of 330MW coal-fired turbogenerator sets, the boiler type is: subcritical parameters, natural circulation, four-corner tangential combustion mode, one-time intermediate reheating, single furnace balanced ventilation, solid-state slag discharge, open-air layout, all-steel frame ∏ Type drum furnace, three-compartment rotary air preheater. The pressure, temperature and flow of main steam and reheat steam should match the parameters of the steam turbine. The temperature of the main steam should be 541°C, and the maximum continuous evaporation capacity (BMCR) should be 1100t / h, finally matching the VWO working condition of the steam turbine. . [0003] At present, there is no relatively complete analysis method for power plant boiler slagging and characteristics, so how to...
