摘　　要：带有合成气冷却器的气化炉,因能将高温合成气中的显热提供给余热锅炉,其系统效率高且更具有研究价值.采用GT PRO软件,研究了余热锅炉和合成气冷却器联合运行的工作过程.模拟和对比了余热锅炉在不同位置抽取和回送冷却介质对系统整体技术、经济性能造成的影响.综合分析之后,提出了几种性价比较高的流程布置.Gasifiers with syngas coolers gain more research value because they can provide sensible heat to HRSG to increase system efficiency. Process match between the heat recovery steam generator （HRSG） and the syngas cooler is investigated by GT PRO. Hot water is extracted from different locations in the HRSG, and resulting steam is sent back to different locations after absorbing heat from hot syngas. Effects of these locations on system technical and economic performance are simulated and compared. Several high capability/price ratio configurations are recommended based on overall analysis.
