利用国外近年来发展起来的热经济学分析方法,作者分析了热电联产供暖系统的优化运行问题。该方法全面考虑了供热系统运行中的能量损耗,包括管网散热,水泵耗功及不可逆传热损失。比热力学第一定律分析法提供了更合理的运行方式。 Using the thermal economic analysis methods developed abroad in recent years, the author analyzed the optimal operation of the combined heat and power system. This method fully considers the energy loss during the operation of the heating system, including the heat dissipation of the pipe network, the power consumption of the pump, and the irreversible heat loss. The first law of thermodynamics analysis method provides a more reasonable way of operating.
