200MW级整体煤气化联合循环系统中燃气轮机的通流匹配特性
The Flow Matching Characteristics of the Gas Turbine in 200 MW Integrated Gasification Combined Cycle System
摘要
Abstract
It is one of keystones to research on integrated gasification combined cycle（IGCC） system that solving gas turbine flow problem and determining the optimal operation condition of the gas turbine burning fuels with medium and low heat value fuel.A 200 MW IGCC unit was researched,and three regulation schemes of gas turbine were prsented from the view of system.The effects of these regulation schemes on the characteristics of the gas turbine and the performance of IGCC system were given.The results show that reducing the compressor inlet airflow or increasing turbine flow area within limits can improve the characteristic of the gas turbine burning low-value syngas and the performance of the IGCC system.Rationally arranging air separation unit（ASU） integrated coefficient（Xas） and nitrogen reinjecting coefficient（Xgn） can increase efficiency of the IGCC system.The parameters of these three regulation schemes all have optimal values which can make the gas turbine and IGCC system have the largest power and efficiency.The results of the research can help to confirm optimal operation condition of gas turbine burning low-heat-value syngas and can also provide convenience for the design and operation of IGCC power plant.关键词
