基于两段式水煤浆气化的IGCC系统变工况特性
Off-design Characteristics of IGCC System Based on Two-stage Coal-slurry Gasification Technology
摘要
Abstract
The integrated gasification combined cycle system(IGCC) is often operated at off-design condition.In order to learn the off-design characteristics of IGCC,the software ThermoFlex was used to establish the model of a 200 MW integrated gasification combined cycle(IGCC) system based on the two-stage coal-slurry gasification technology.The effects of gas turbine load,air separation unit integrated coefficient(Xas),atmosphere temperature and atmosphere pressure on the performance of IGCC system were investigated.The results show that gross and net electric efficiency increases at first and then decreases with atmosphere temperature increasing or gas turbine load decreasing.The gross electric efficiency decreases when the air separation unit integrated coefficient increases.Atmosphere pressure has little effect on system efficiency.The application of two-stage coal-slurry gasification technology has good availability to improve IGCC system performance under the above running conditions.The results will provide reference for design and operation of the IGCC power plant.关键词
