摘要
我国未来十年的煤基发电预期在电力供应中所占比重将有较大增长,随着发电用煤量的增加,气体、液体和固体废物的排放亦随之增加。为此,需着手新技术的开发。煤气化联合循环发电同时采用燃气轮机和蒸汽轮机发电,使环境控制和总系统效率有相当大的提高。本文概述了煤气化联合循环发电的概念和特点,同时对其系统效率进行了分析和作出评价。
The coal based electricity generation is expected to contribute an even greater share of the electricity supply in next decade in China Along with the increase in coal consumption in power plants, the associated increase in emission of gaseous, liquid and solid wastes has given rise to some concern, these concerns must be addressed by development of improved technology. Integratedgasification combined cyclesystem, using both gasand steam turbine offers significant improvement in overall system efficiency and environmental benefits. This paper generalizes thh concept and features of coal based integrated gasification combined cycle power generation. The analvsis of overall system efficiency and evaluation of it are also discussed.
