摘　　要：介绍了一种加压煤气化工艺中,能够在带压状态下干式冷却气化反应产生的高温灰渣的换热设备设计及应用。阐述了设备结构设计中的难点与要点,并对结构选型、主要受压元件的强度计算方法进行了比较详细的分析,对合理设计换热器,保证换热器安全高效的参与生产具有指导意义和实用价值。In this paper, a kind of heat exchanging equipment for high temperature ash produced by dry cooling gasification re- action in pressurized coal gasification process is introduced, as well as its design method and application. The difficulty and key points of structural design are described ; the structure type selection and the strength calculation method of the main pres- sure parts are analyzed in detail. Thus it has guiding significance and practical value for reasonable design of heat exchanger so as to ensure the safe and efficient participation of production in future.
