我国工业炉窑热效率低,燃料消耗高,是普遍现象。其主要原因之一,就是现在运行的工业炉窑大多数没有安装余热回收利用设备,大量的余热资源未能利用。因此,采取各种先进节能技术措施回收利用炉窑余热,是提高炉窑热效率、降低燃耗,合理充分利用能源的重要环节之一。工业炉窑余热资源丰富我国工业炉窑余热资源是比较丰富的。据估计冶金、建材、化工、轻工等行业中炉窑余热 China’s industrial furnace kilns low thermal efficiency, high fuel consumption, is a common phenomenon. One of the main reasons is that most industrial kilns operating nowadays do not have the equipment for waste heat recovery and utilization, and a large amount of waste heat resources can not be utilized. Therefore, taking all kinds of advanced energy-saving technical measures to recycle waste heat from the kiln is one of the important steps to improve the thermal efficiency of the kiln, reduce the fuel consumption and make reasonable use of energy. Industrial furnace waste heat rich in resources China’s industrial furnace waste heat resources are more abundant. It is estimated that metallurgy, building materials, chemicals, light industry and other industries in the furnace kiln heat
