水分和灰分对煤炭发热量的影响研究

alorific value of coal is an important indicator of the quality assessment of coal by coal moisture and ash are more significant. Firstly, the gray theory, by calculating the correlation of gray that integrated water and coal ash affecting the drivers of heat and moisture and ash gray under the comprehensive relationship between the relative correlation of ash are the main drivers of note. Then the establishment of multiple regression analysis based on the calorific value of coal moisture and ash content of coal in the multiple regression model, check that the model can be adopted for the prediction of coal heat.
