With the more and more profound understanding of the atmospheric environment,the emission requirements of heating boilers become more and more stringent. In this context,the main research object of this paper is coal-fired and gas-fired heating boilers. Based on the analysis of the second law,the characteristics of heating boilers are analyzed from the angle of loss of useful energy or transfer of available energy to the environment,and a series of conclusions are drawn.For various types of boilers,including coal-fired hot water,coal-fired steam,gas-fired hot water and gas-fired steam boilers,the overall black-box model of the boiler system is built,and the balance calculation is carried out by using external data,the efficiency of the process is obtained,and the conclusion is drawn through comparative analysis.
