Other AbstractSeveral key factors that influence boile r heat loss and efficiency are introduced,through simplifying the model of boiler system,the effects of exhaust gas temperature,excess air coefficient and inlet cold air on thermal efficiency and exhaust heat loss of boiler are analyzed by numerical simulation. A comprehensive evaluation model is built by using analytic hierarchy process,the weight of each factor is analyzed in a comprehensive objection way. The results show that the exhaust gas temperature or the temperature of the cold air increases from 10 ℃ to 15 ℃,the heat loss of the boiler flue gas reduces from 0.8% to 1%,and the thermal efficiency of the boiler increases from 0.8% to 1%; the key factors that affect the thermal efficiency of the boiler are exhaust gas temperature and fuel volatile,the proportion of the two weights are 33.6% and 16.8% respectively. In the end,seven optimization schemes are put forward for a boiler plant in Beijing. The results show that the layered combustion technology,adding air preheater and heat preservation measures,can improve the thermal efficiency of the boiler effectively. These studies will provide a theoretical basis for the energy saving renovation program of boiler system.
