回热系统是火电厂热力系统的重要组成部分 ,也是进行热力计算的重点。文章在建立了热力系统加热器的通用性数学模型的基础上 ,用循环函数法对整个回热系统进行热力计算。将循环函数法进行了改进、并应用到实时热力计算中 ,应用实例表明此种方法概念明确、结果准确、容易在实时计算中实现等特点。
Regeneration system is an important part of thermal power plant thermal power system, but also the focus of the thermal calculation. Based on the establishment of a universal mathematic model of the heating system heater, the article calculates the thermal performance of the entire heating system by the method of the circulating function. The method of cyclic function is improved and applied to the real-time thermodynamic calculation. The application examples show that this method has the advantages of clear concept, accurate result and easy realization in real-time calculation.
