摘　　要：基于循环函数法,从热化发电率和热电联产节煤量的算法出发,阐明热化发电率与热电厂经济性的关系。分析表明,热电联产节煤量与外部热化发电率以及内、外部热化发电率之比有关,但主要由外部热化发电率决定,外部热化发电率越大,热电厂的经济性越好;当外部热化发电率一定时,内、外部热化发电率之比越大,热电厂的经济性越好。通过具体的算例验证了以上结论。Based on the cycling function method,and starting from the algorithm of power generation rate from thermalization and of the saved coal amount from heat- and- electricity co- generation, the relationship between power generation rate from thermalization and saved coal amour from heat - and - electricity co - generation has been expounded. Analysis shows that the saved coal amount from heat -and -electricity co -generation is relating to the external power generation rate from thermalization,as well as the ratio between internal and external power generation rate from thermalization, however, it is mainly determined by the external power generation rate from thermalization,the bigger the external power generation rate from thermalization is, the better economic efficiency of the thermal power plant becomes;in the event of certain external power generation rate from thermalization, the greater ratio of internal to external power generation rate from thermalization is, the better economic efficiency of a thermal power plant becomes. The above - mentioned conclusions have already been verified through concrete examples of calculation. cycling function method; power generation rate from
