Study on Influencing Factors of Coal Quality in Coal Blending

Abstract

In this paper, the indexes of various single coal are determined, and the influencing factors of coal blending are studied by changing different proportions. The experimental results showed that water content had no change rule and had little effect on coal blending index. The ash content in coal increases, the calorific value decreases. The volatilization has additivity which is directly proportional to the calorific value of coal. Sulfur content has great influence on processing equipment and environment. Sulfur content has additivity.
