| 摘 要： | 鉴于目前高炉渣显热不能得到有效的回收利用,以空气和水为换热介质,进行了干式粒化高炉渣显热的回收实验,研究了熔渣质量流量和空气体积流量对空气预热温度、水预热温度和余热回收率的影响.实验结果表明：随着熔渣质量的增加,空气预热温度和水预热温度均增加,同时余热回收率减小;当空气流量的增加时,虽然空气和水的预热温度都降低,但余热回收率升高.

| Abstract: | Because heat energy in molten slag is unable to efficiently recover, primary heat recovery from dry granulation molten blast furnace slag experiment was done using water and air as heat medium. The relations between slag mass flow and air flow between tem- perature of air, temperature of water and heat recovery rate were studied. The experimental results indicated that temperature of air and water increased with increasing slag mass flow, but heat recovery rate reduced. When the air flow increased, heat recovery rate increased, while temperature of air and water decreased. |
