Analyzing the effect of vacuum system's tightness on thermal economy of steam turbine by using dynamic simulation

摘要

In the paper, through establishing dynamic simulation mathematical model, the effect of vacuum system's tightness on thermal economy of steam turbine has been analyzed based on the experiment. At the same time, through analyzing the seeking of a substitute for the experiment on vacuum tightness, to evaluate the way that vacuum tightness of steam turbine effects thermal economy. The conclusion of this paper has reference value for evaluating the effect of vacuum system's tightness on thermal economy of steam turbine.
