摘要
Abstract
Coal is still the main fuel used in integrated gasification combined cycle(IGCC)power plant.To adapt to the requirements of"three-renovation"from the country and meet actual demand of customer,the study was conducted on renovations for steam turbine in an integrated gas combined cycle power plant from aspects of energy-saving,heating and operation flexibility.Comparison was carried out among different renovation schemes to analyze their technical paths and economic efficiency,and it was determined that the scheme of double-rotor and heating by recirculating water was the optimal one.This scheme consisted of flow path renovation during non-heating season and heating renovation of high backpressure circulating water during heating season.The performance indexes would be significantly improved by adopting this scheme:in turbine heat acceptance condition,the heat consumption in pure condensing condition would be reduced by about 5.15%,and the power output would be increased by about 8.4%;the heating supply would be about 186.67 MW.This scheme is of considerable economic and social benefit,and can provide reference for"three-renovation"of similar units.关键词
