Experimental analysis on blended burning of multiple kinds of coal in 630MW supercritical boiler

Abstract

Abstract: In the 630MW supercritical boiler of a power plant, the multiple kinds of coal produced in Indonesia, Guizhou Province of China, Columbia, Australia and South Africa were blended and burned. The features of the blended burning of multiple coal grades were analyzed. The ratio of each kind coal in the coal as fired and the blending mode were expounded, and the matters needing attention in blending of multiple kinds of coal were pointed out. The experience of the plant in blended burning of multiple kinds of coal can be used as reference for similar power plants.

Key words: 630MW supercritical boiler, blended burning, slagging, load, economical efficiency
