通过对热电联产系统中能量利用过程的分析 ,引入可利用无效能和折合炬用概念 ,合理评价了炬用和无效能在实际热能利用过程中的不同作用 ,建立了以折合炬用概念为基础的面向热能利用过程的折合炬用热电分摊模型及简化模型。对大量典型机组运行工况的计算表明 ,热电费用分摊模型具有物理意义清晰 ,计算结果合理 ,可为实际应用提供参考依据 Through the analysis of the energy utilization process in cogeneration system, the concept of available inefficiency and torch was introduced, the different roles of torch and ineffective energy in actual heat energy utilization were reasonably evaluated, and the concept of torch used Fundamentals of heat-power sharing models and simplified models for torch-based thermal energy utilization processes. The calculation of operating conditions of a large number of typical units shows that the model of thermoelectricity cost apportionment has a clear physical meaning and a reasonable calculation result, which can provide a reference for practical application
