When a boiler operates under a wet type slag removal mode, high temperature red hot slag in contact with suddenly cooled water seal water will give rise to a subcooled boiling. The water vapor generated by the subcooled boiling will increase the heat loss of exhaust gases, thus influencing the boiler thermal balance calculation and measurement/test results. 锅炉在湿式除渣方式下运行时 ,高温炽热的炉渣与激冷的水封水接触产生过冷沸腾 ;过冷沸腾所产生的水蒸气使排烟热损失加大 ,影响了锅炉热平衡的计算与测试结果。 Test procedures of gas' water seal water of Jinan Iron &Steel Co.were presented and practical engineering treating measures were described.A chemical method suitably to treat gas' water seal water containing high den sity cyanide drained largely was dis cussed.[ 阐述了济钢煤气水封水的实验处理过程及实际工程处理措施。探索一种适合于大流量下,高氰化物浓度的化学处理煤气水封水的方法。
