建立了换热器传热熵产的理论模型,然后利用采集的某火电厂实时运行数据计算得出锅炉运行中换热器的传热熵产变化曲线,并分析了负荷变化和负荷稳定过程中影响其熵产变化的因素,最终提出了可以利用传热熵产监测受热面清洁状况进而开发基于熵产最小理论的吹灰优化新策略的理念。 The theoretical model of heat transfer entropy generation of heat exchanger is established. Then, the heat transfer entropy production curve of the heat exchanger in boiler operation is calculated by using the real-time operation data collected from a thermal power plant. The process of load change and load stabilization are analyzed Finally, the author put forward the idea of ​​using heat transfer entropy to monitor the cleaning condition of heated surface and then develop a new soot blowing optimization strategy based on entropy production minimization.
