摘　　要：对于单热源供热系统,为了保证设计热负荷的需要,通常供热设备要设置相当大的装机容量,这使得集中供热初投资大、可靠性差、热源效率低下。基于此,在充分掌握热源(燃煤锅炉、燃气锅炉)特性、地域特性及建筑用能特性的基础上,本文以供热系统全寿命周期内经济费用年值和社会成本费用年值最小为目标,对某单热源供热系统燃气调峰热源的设置进行了优化,得出了与调峰热源特性相匹配的最佳容量和调峰运行时间。分析可知,设置燃气调峰热源具有较好的经济效益、环保效益和社会效益。For a single heat source heating system,in order to ensure the design heating load,the heating appliances are usually equipped with a large capacity,which lead to the large initial investment,less reliability and poor heat efficiency.In this paper,basing on the characteristics of heat source（coal-fired boiler,gas boiler）,features of geography and characteristics of building energy consumption,the minimum values of economic and social annual costs in full life-cycle of heating system were taken as the research targets,the establishment of gas peak-shaving heat source in single heat source heating system was optimized,and the best equipment capacity and peak-shaving running time were determined.With this system,the better economic,environmental and social benefits could be achieved.
