Study on the industrial analysis and calorific value of coal blending

Yan Min Zhang, Guo Zhe Guo, La La Zhang, Hu Jun Wang

Abstract

The industrial analysis of coal can reflect the characteristics of coal and correctly evaluate the coal quality. The water, ash, volatile and fixed carbon in coal is determined by industrial analyzer. We can preliminarily judge the properties, type of coal and the way of coal processing. Calorific value is an important index for power coal blending, so measuring and analyzing calorific value is very important for coal blending. In this paper, Jing Yuan coal, Hua Ting coal and Ning Xia coal are used to analyze the effects of various indexes on calorific value.
