摘要: 为客观评价热电厂作为市场经济主体的热经济性,以供热机组燃料输入与产品输出为研究对象,在综合考虑热电联产机组供热量与发电电量经济价值的基础上,提出了热电厂经济效益系数的概念,并建立了该概念的计算模型。该模型从宏观经济性的角度出发,提出以单位燃料消耗量产生的经济价值来考核热电厂能量利用效率的方法,弥补了传统方法以能量数量和品质分析热电联产机组成本分摊方法的不足,具有一定的市场经济学意义。通过对某国产300 MW抽凝式机组进行实例计算表明,该计算方法简单实用,可以为制定合理的热电市场价格和热电负荷调度提供有效的解决方案。

Abstract: In order to evaluate the efficiency of cogeneration power plants as the main body of the market economy, taking the fuel input and product output of cogeneration units as the study objectives, the concept of economic benefits coefficient is proposed by considering the economic value of the heating and generating capacities of cogeneration units. The calculation model of the concept is also established. From the perspective of macro economy, the method based on the economic value generated by unit fuel consumption is proposed to assess the energy efficiency of cogeneration power plants. It overcomes the disadvantage of the traditional method that uses the quantity and quality of energy to analyze the cogeneration unit cost allocation, and has some market economics significance. In addition, a sample calculation is given based on a 300-MW extraction condensing turbine. The results indicate that the calculation method is simple and practical, and can provide effective solution to reasonable heat and power pricing and scheduling.

Key words: heat and power cogeneration, product, coefficient of economic benefits, energy efficiency
