Analysis and Prediction on Carbon Potential Emission Factors of Combusted Coal

The statistic and analysis on the coal potential emission factors of the different coal carbons showed that the potential emission factors of the carbon wo uld have an obvious V type variation tendency with the coal metamorphic degree increased.Based on the study on the relevant relationship between the potential emiss ion factors of the carbon and different reference normal coal quality index, the relevant closed coal quality indexes were collected.With the multi element linear regressi on analysis on 1 676 measured coal quality data, the regression equation of the carbon potential emission factors was obtained.The conventional coal quality data coul d be applied to predict the carbon potential emission factors.According to the coal metamorphic degree, the coal in China could be divided into five major grades.A regr ession analysis on the carbon potential emission factor of each grade was conducted and thus the accuracy of the regression equation was improved.
