    • A method for producing pulverized coal including the steps of providing a drying gas heated to a predefined temperature in a hot gas generator; feeding the heated drying gas into a pulverizer; introducing raw coal into the pulverizer, the pulverizer grinding the raw coal into pulverized coal; collecting a mixture of drying gas and pulverized coal from the pulverizer and feeding the mixture to a filter, the filter separating the dried pulverized coal from the drying gas; collecting the dried pulverized coal for further use and feeding the drying gas from the filter to an exhaust line; and collecting the drying gas exiting the filter and feeding part of the collected drying gas to a recirculation line for feeding recirculation drying gas to the hot gas generator. According to an important aspect of the present invention, the step of providing the drying gas includes feeding a variable flow rate of hot stove waste gas to the hot gas generator through a hot stove waste gas line so as to maximize the amount of hot stove waste gas used as drying gas. A pressure of the drying gas at a pulverizer gas inlet is controlled by regulating a flow rate of the hot stove waste gas through the hot stove waste gas line.
    • 一种生产粉煤的方法,包括以下步骤:在热气发生器中提供加热到预定温度的干燥气体; 将加热的干燥气体进料到粉碎机中; 将原煤引入粉碎机中,粉碎机将原煤研磨成粉煤​​; 从粉碎机收集干燥气体和粉煤的混合物,并将混合物送入过滤器,过滤器将干燥的粉煤与干燥气体分离; 收集干燥的粉煤进一步使用,并将干燥气体从过滤器供给到排气管线; 并收集离开过滤器的干燥气体并将收集的干燥气体的一部分供给到用于将再循环干燥气体供给到热气体发生器的再循环管线。 根据本发明的重要方面,提供干燥气体的步骤包括通过热炉废气管线向热气发生器供给可变流量的热炉废气,以便最大限度地发挥热炉废物的量 气体用作干燥气体。 通过调节热炉废气通过热炉废气管线的流量来控制粉碎机气体入口处的干燥气体的压力。
