联合循环机组蒸汽参数选择和运行方式分析

基于热力学和自动控制的理论基础,结合国内部分燃气—蒸汽联合循环机组的生产运行实际情况,提出了对于联合循环方式下运行的机组,其蒸汽侧的温度和压力参数选择的较为合理的分析原则。同时在依据国内某机组实际运行数据的基础上,分析了汽轮机滑压运行的控制方法和热效率特性。

The Steam Parameter Selection and Operation Mode Analysis of the Combine Cycle Generating Set

Based on theoretical foundation of thermodynamics and automatic contral,according to the real condition of production and operation in the domestic part of gas-steam combine cycle generating set,the more reasonable principle for selecting the pressure parameter and its steam side temperature was put forwards.Meanwhile,based on the operating data of a domestic unit,the control method and thermal efficiency,under sliding pressure operation condition,were analysed.
