The influence ofcalorificvalueofcoal and carbon-content of cinder on the heat loss from solid incomplete combustion of the boiler were analysed in the paper.
Regression relation for computing the gross calorificvalueofcoal is discussed through analysis of affected factors, the results between computing and test ware compared.
