摘　　要：针对电炉炼钢过程中产生的大量非稳态高温烟气,通过采用经济的水-碳钢热管式蒸汽发生装置及系统进行余热回收,研究合理的多单元模块式结构与冲击波强力清灰方式,解决了其灰堵、磨损、腐蚀、热应力等问题,有效地将烟气温度从1 000℃降至180℃以下进入后续除尘设备并达标排放,达到了余热利用、节约能源的目的。Large quantity of non-steady-state high temperature waste fume may generate in the process of EAF steelmaking. In view of this fact residual heat recovery is carried out by means of a water-carbon steel hot pipe type steam generating device and system. The problems such as ash blockage, wear, corrosion and thermal stress have been effec- tively solved by research and development of the appropriate multi-element module structure as well as the ash removal method using powerful shock wave and thus the temperature of the waste fume is effectively lowered to less than 180 ℃ from the original 1 000 ℃ and then it will be delivered to the down stream dust removal device and finally let off. In this way both the purposes of reclamation of residual heat and energy saving can be realized.
