摘要
蒸汽侧汽温调节所采用的喷水减温方法不同对系统经济性影响也不同。本文基于热平衡分析,推导相应的等效焓降算法模型,并提出变工况下不同喷水方式对经济性影响的分析算法及算例,改善了等效焓降法的局部定量分析精度。
Steam temperature regulation on steam side adopted by the different methods spray desuperheater, the economic influ- ence of the system is also different. Based on the heat balance analysis, the model of equivalent enthalpy drop Algorithm was derived, and proposed the algorithm and gave the example by different way of water spraying at change-condition, improved the accuracy of local quantitative analysis with the method of equivalent enthalpy drop.
