汽轮机通流效率考核试验的修正问题

Correction Problem about the Acceptance Test of the Turbine Flow Passage Retrofit

通过对汽轮机通流效率考核试验修正原理的分析,探讨了通流效率考核试验的修正项目、修正计算的思路和方法等相关问题。建立了修正计算的一般模型,并以某台机组为例进行了模型的验算,验证了该文提出的修正计算方法和计算模型的正确性。

By analyzing the basic principle of the correction about the acceptance test of the turbine flow passage retrofit, some important items about correction are put forward such as the ways and methods of correction calculation, correction items of test results about the acceptance test to flow efficiency. The general mathematical models of correction calculation are set up for the first time. All of above methods and mathematical models are verified in practical application.
