摘　　要：建立考虑漏风因素的烧结矿冷却热平衡模型,再通过简易热工测试获得烟气温度数据,通过获得烟气温度拟合沿环冷机圆周的温度分布曲线,从而计算出漏风率。建立的漏风率计算模型,对某钢厂的2台396 m^2环冷机进行漏风率计算,并将计算结果与已有文献数据做对比,验证了所建立的漏风率计算模型的合理性,表明所建立的漏风率计算模型适用于环冷机烟气余热资源估算和余热发电工程设计。By establishing a heat balance model for sinter cooling with consideration of the air leakage factor,getting the flue gas temperature data by ways of the simple thermodynamic measurements and obtaining the fitted curves on the flue gas temperature distribution around the circular-cooler,the paper calculated out the air leakage rate. By use of the established calculation model for air leakage rate,the paper made the calculation on the air leakage rate for 2 sets of 396 m^2 sintering circular-cooler of a steel mill,compared the calculating results with the available published data and verified the reasonability of the established calculation model for air leakage rate. The result indicates the established calculation model for air leakage rate can apply to the estimation of circular-cooler waste heat resource as well as the design of waste heat power generation projects.
