双压再热余热锅炉蒸汽参数优化与分析

Optimization and analysis of steam parameters of heat recovery steam generator in combined circle

本文对联合循环系统双压再热余热锅炉的蒸汽参数进行了优化研究，计算并总结了最优化的蒸汽压力、蒸汽流量以及回收量随余热锅炉进口燃气参数的变化规律．其结果对联合循环余热锅炉的优化设计县有理论意义和实用价值．

The results of optimizing parameters of dual-pressure-reheat heat recovery steam generator are presented.This paper generalized the regularity of variations of the optimum steam pressures, the optimum steam mass flow and the exergy recovered with the gas turbine exhaust temperature and mass flow varying.The results would be instructive to optimizing design of HRSG.
