电站锅炉熵产分析模型及应用

Utility Boiler Entropy Generation Analysis Model and Application

本文应用单耗分析理论,根据锅炉各设备所发生的热力学过程,分析这些过程的不可逆性,结合熵平衡分析方法,推导出详尽的电站锅炉熵产分析模型,实例计算中,利用该模型针对某超超临界机组进行了分析,提出了节能改造的指导性建议,绘制了该机组锅炉的熵平衡T-△S图。

In this paper,The specific consumption theory is used in analyzing irreversibility of thermodynamic processes which occurred in each device in boiler.Detailed entropy generation analysis models of power plant boilers are proposed by using entropy balance analysis method.Examples of calculation for a ultra-supercritical units,and energy-saving advice and boiler entropy balance T — △S map are proposed.
