Abstract

The invention discloses a method and a device for rapidly characterizing contamination characteristics of coal ash. The method mainly comprises the steps that pulverized coal is conveyed into the experimental device to be combusted, ash particles and smoke are generated and flow through the porous filter plate, and the ash particles are intercepted by the filter plate; after the filter plate is taken out, the loose ash particles are removed, and the remaining ash particles are adhesive ash; then the value of a physical quantity index R = (G3-G1)/(G2-G1) is calculated according to the initial mass G1 of the filter plate, the mass G2 after the ash particles are intercepted and the mass G3 after the loose ash particles are removed, and the contamination characteristic is judged. The device comprises a gas distribution device, a powder feeder, a reaction tube, an electric heating furnace, a filter plate, a sucking pump and the like, and the filter plate is formed by sintering metal powder and located at the downstream section of the reaction tube. According to the method, high-efficiency and reliable characterization of the contamination characteristics of the coal ash is realized, the contamination characteristics of the in-furnace fuel of the power station boiler can be warned in time, and the operation safety of the boiler is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of combustion of pulverized coal boilers, and in particular relates to detection means for slagging and contamination of coal species, in particular to a method and device for rapidly characterizing coal ash contamination characteristics. Background technique [0002] Many coal resources have strong slagging and contamination characteristics, which are not conducive to the safe and stable operation of coal-fired power plant boilers. Boiler slagging mainly refers to the formation of a slag layer when molten or molten ash contacts the heating surface, which generally occurs on the water wall of the furnace and the bottom of the panel superheater; while boiler fouling mainly refers to the deposition and bonding of solid ash particles on the heating surface to form stains. Dirt layer can occur on the heating surface of furnace water wall, panel superheater, high temperature superheater, high temperature reheater...
