摘要
对区域单热源供热系统调峰热源设置进行方案设计,以提高供热系统可靠性、热源运行效率及降低主热源初投资.在充分掌握燃煤锅炉与电锅炉特性、地域特性及建筑用能特性的基础上,采用费用年值法对某单热源供热系统调峰热源的设置进行优化分析,得出与调峰热源特性相匹配的最佳容量和启动温度.当低谷电价为0.25元/kWh时,对于石家庄地区的系统最佳基础容量系数约为0.7,全寿命周期内经济费用年值节省约270万元;对于哈尔滨地区的系统最佳基础热源容量系数约为0.75,全寿命周期内经济费用年值节省约171万元.
In order to improve the system reliability and the heat source efficiency and reduce initial investment,the design project is proposed to set up peak-shaving heat source of regional single heat source heating system.Based on the coal-fired boilers and electric boiler characteristics,geographical features and architectural energy characteristics,the peak-shaving heat source of some single heat source heating system is optimized by annual cost method.The best capacity and startup temperature matching the peak-shaving heat source characteristics have been confirmed.When the valley electrovalence is 0.25 yuan / kWh,the best basis capacity factor of heating system is 0.7 and full life-cycle economic cost is saved about 2.7 million in Shijiazhuang area,the best basis capacity factor of heating system is 0.75 and full life-cycle economic cost is saved about 1.71 million in Harbin area.
