摘要
合理的电价和热价有利于推动热电联产事业的发展,热电联产项目的热价和电价主要与其成本有很大关系。文中对热、电成本分摊比进行分析研究得出:对于可变成本应按热量法求出燃料消耗比来分摊,对于供采暖热负荷的两用机组将其供热发电节煤量的1/3效益补贴在供热方面是合理的;对于固定成本与财务费用,小型热电厂以燃料分摊比来分摊计算是可行的,而两用机组按纯供热投资所占两用机组总投资的百分比,或按平均供热抽汽量计算出减少的发电量与额定发电量的比值来分摊是合理的。
The reasonable electricity price and heat price are beneficial to the development of cogeneration utilities, the heat price and electricity price are mainly connected with their costs. The analysis and study of cost allocation ratio in the paper come to the following conclusions: the allocation of variable cost should base on the fuel consumption ratio resulted from the thermal method; for the heating load of dual-purpose unit, it is reasonable to compensate it the one third of coal saved in cogeneration; for fixed cost and financial cost, it is feasible to calculate the allocation ratio based on the fuel allocation ratio for the small size cogeneration power plant, it is also reasonable to calculate the allocation ratio lased on the ratio of the investment for heating to the total investment or based on the ratio of the decreased power generation to the rated power generation according to the average extracted steam quantity for heat supply.
