摘要
介绍某钢铁企业近5个月的高炉冲渣水直接换热供暖应用情况。结果显示:新型无触点的单通道换热器可以有效避免冲渣水杂质对换热器的堵塞和腐蚀。冲渣水经过换热后,温度能降低到55℃以下,满足冲渣工艺用水要求,而采暖水温度则能够从50℃提高到67.7℃,满足供暖要求。该系统经济效益和环境效益都十分突出。
A direct heat transfer with blast furnace waste for heating water was introduced, which has been running for nearly 5 months in a iron and steel factory in China. The operation results showed that the new single channel heat exchanger without contact point could avoid corrosion and block problems caused by impurity in blast furnace waste water. The temperature of slag flushing water through the heat exchanger can be reduced to less than 55 ℃ which meets the requirement of flush slag process. The heating water temperature can be increased from 50 ℃ to 67. 7℃ which meets the heating requirements. The economic and environmental benefits of the system are significant.
