新汶矿区煤炭发热量与灰分的相关关系及其应用

Research and application of the correlativity between calorific value and ash of coal in Xinwen Mining Area

对新汶矿区煤炭发热量和灰分的相关性进行了分析,由此推导出的回归方程可应用于实际工作中换算该矿区煤炭的干基高位发热量和收到基低位发热量。

The correlativity between calorific value and ash of coal is analyzed. By the correlation analysis, the regressive equations are obtained. In actual work, the equations can be used to calculate the gross calorific value （dry basis） and the net calorific value （as received basis） of coal in Xinwen Mining Area.
