Cement clinker sintering heat consumption calculation method based on flue gas component analysis

The invention provides a cement clinker sintering heat consumption calculation method based on flue gas component analysis. The method comprises the following steps: (1) collecting flue gas components x(N ), x(O ), x(CO) and x(CO ); (2) calculating the amount m of pure carbon participating in combustion; (3) calculating the heat consumption Q of cement clinker production; (4) calculating the cement clinker yield P; and (5) calculating the cement clinker firing heat consumption p. The method has the advantages of simple process operation, real-time monitoring and no dependence on the statistical data of the fire coal inventory, can effectively reduce the interference of human factors in the cement clinker firing heat consumption calculation process, and improves the accuracy of the monitoring result of the cement clinker production energy consumption. The method can be used for calculating the unit yield and unit consumption of the cement clinker, can also be used for real-time online monitoring of the heat co
