凝汽器传热端差的计算与分析

Calculating and Analyzing the Temperature Difference of Condenser

对凝汽器传热端差的各个主要影响因素及它们之间的关系进行分析,解释了有关表达式及相关概念难以理解的问题,利用不同容量级机组的有关参数进行计算,并联系工程实际,进一步验证分析方法及结果的正确性。该结果不仅适用于凝汽器端差的分析,对于其它换热器的传热端差计算同样具有实用意义。

The temperature difference of condenser is a very important parameter in power plant and is not understood clearly in research of theory and practice. Based on the analysis of the factors of condenser's temperature difference and the relation among themselves, some beyond understanding questions of the expression and conception are made clear. According to the calculation (based on the design parameters of different capacity level) and the engineering facts, the analysis and the result are proved again. The result is the same with others heat exchanger.
