燃气调峰集中供热系统技术经济分析OA
Techno-Economic Analysis of Central Heating System Based on Gas Peak-Shaving
结合工程实例,利用供暖热负荷延续时间图的方法研究燃气调峰集中供热系统的经济性,计算不同室外温度时启动调峰燃气锅炉的费用.随着启动调峰燃气锅炉的室外温度升高,燃气调峰集中供热系统总费用先下降后上升,存在极小值.最佳启动调峰燃气锅炉的室外温度为-3 ℃.
Combined with engineering cases,the economy of central heating systems based on gas peak-shaving was studied using the heating load duration curve method,and the operating costs of peak-shaving gas boilers at different outdoor temperatures were cal-culated.As the outdoor temperature for starting peak-shaving gas boilers increases,the total cost of the cen-tral heating system based on gas peak-shaving first decreases and then rises,showing a minimum value.The optimal outdoor temperature for starting peak-shav-ing gas boilers is-3℃.
