    • PURPOSE: An EGR(Exhaust Gas Recirculation) type aggregate dryer having a rotating drum is provided to maximize the fuel use efficiency of a rotating drum aggregate dryer by applying the EGR technique and to reduce the fuel consumption by using the waste heat of the exhaust gas. CONSTITUTION: Aggregate(8) put into a rotating drum(1) is dried by contacting to the hot combustion gas(11) supplied from a burner(2). To recover the waste heat of the exhaust gas(12) discharged from an aggregate dryer, the exhaust gas is recirculated by a recirculation flow rate control valve(4) and a recirculation fan(3). The recirculated exhaust gas is mixed with the external air(10). The mixed air is supplied to the burner.
    • 目的:提供具有旋转鼓的EGR(排气再循环)型集料干燥器,以通过应用EGR技术来最大化旋转鼓集料干燥器的燃料利用效率,并且通过使用废气的废热来降低燃料消耗 。 构成:放入旋转鼓(1)中的聚集体(8)通过与从燃烧器(2)供应的热燃烧气体(11)接触而被干燥。 为了回收从聚集干燥器排出的废气(12)的废热,排气通过再循环流量控制阀(4)和再循环风扇(3)再循环。 再循环废气与外部空气(10)混合。 混合空气供给燃烧器。
