Abstract

Abstract: The reasons of coking occurred in a power plant due to firing highsulfur coal produced in Guizhou province were analyzed. The improvement measures were introduced, which were adopted by the power plant to alleviate the coking. These measures involve the coal blending, the air distribution, the oxygen control, the equipment reformation and other aspects. The coking was controlled effectively due to these measures without basic improvement of the coal grade.

Key words: high-sulfur coal, coking, analysis, measure
