摘　　要：针对目前中高温气体余热利用方式存在的问题,提出一种余热深度利用新技术:吸收式气-水换热技术.分析了该技术的原理、特点、适用条件等,通过示范工程的案例研究,详细分析了应用该项技术后能源系统的能效水平.研究结果表明,该项技术使得中高温气体的排烟温度不受到用户处热要求的限制,可降低到30℃以下,使能源利用效率可以提高10%,且可减少废气中NOx,SO2等污染物排放.The problem of heat recovery of waste gas with medium or high temperature was analyzed,and an innovative absorption gas-water heat exchange technology to recover the waste heat deeply was proposed.The principle,characteristic,and application conditions were analyzed,and the energy efficiency of a system using the technology was analyzed by a demonstration project.It is shown that the temperature of the off gas is not confined to the second side of the heat exchanger,and it could be reduced to below 30℃.The energy efficiency could be improved by 10%,and the NOx and SO2 could be reduced.

关 键 词：吸收式气-水换热技术 余热回收 热源利用效率
