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 heat load, the heating equipment to be set to a considerable amount of installed capacity, which makes the initial investment of centralized heating, poor reliability, low heat efficiency. Based on this, on the basis of fully grasping the characteristics of heat sources (coal-fired boilers, gas boilers), regional characteristics and building energy characteristics, this paper aims at minimizing the annual value of annual cost and social cost of heating system in the whole life cycle , The optimization of the setting of gas peak heat source of a single heat source heating system has been made and the optimum capacity and peak operation time matching the characteristics of peak heat source have been obtained. Analysis shows that the setting of gas peak heat source has good economic benefits, environmental benefits and social benefits.
