摘　　要：以我国目前超超临界锅炉技术为基础,探讨了开发和设计大容量超超临界褐煤锅炉的必要性,提出1 000 MW超超临界褐煤锅炉的初步设计方案,主要包括煤质资料、蒸汽参数的选择、炉膛型式和主要特征参数、炉膛水冷壁、燃烧及制粉系统、过热器、再热器和省煤器系统、调温方式、启动系统、承压部件的钢材等.Based on the existed domestic ultra-supercritical boiler technology,the necessity of developing and designing large capacity ultra-supercritical lignite-fired boiler is discussed.The basic design scheme of a 1 000 MW ultra-supercritical lignite-fired boiler is presented,including the selection of coal and steam parameters,furnace type and main characteristic parameters,furnace waterwall,combustion and coal-pulverizing system,superheater,reheater and economizer system,temperature controlling method,start-up system,steel of pressure parts,etc.
