信息论应用于测量技术中是有效的,但没有热效率测试方面的应用实例。首先对信息论作了介绍,并对信息熵和熵系数作了详细阐述。在邹县发电厂 1号炉热效率测试中,以信息论作为理论依据,对排烟温度和排烟氧量这两个影响锅炉热效率最重要参数的试验数据进行处理和误差分析,并对测试方法和准确性作出评价,给评定锅炉性能状况提供一些参考性意见。 Information theory is useful in measurement techniques, but there are no examples of thermal efficiency tests. Information theory is first introduced, and information entropy and entropy coefficients are elaborated. In the thermal efficiency test of No. 1 furnace in Zouxian Power Plant, based on the theory of information, the test data of the two most important parameters that affect the thermal efficiency of the boiler, such as the exhaust gas temperature and the exhaust oxygen, were processed and analyzed. The test methods and The accuracy of evaluation, to assess the performance of the boiler to provide some reference.
