密得莱达—罗斯(Midland—Ross)公司的罗斯—华达(Ross—Waldron)分公司制造了一种经济的再生式热交换器,它具有从高温烟气中回收热量并可予热冷空气和炉子烟气的优点。这是一种流化床式的热交换器,它是一个带保温层的圆筒形塔(如附图),塔由上下两部分组成。每个室都有几层钻孔水平圆盘。塔的直径为1.8～3.6米,高约7.6～15米,能满足各种冷风和烟气量的需要。辅助设备包括一个气力系统,将热交换介质(即高铝小球)从塔的底部输送到顶部,它由气力泵和靠近塔体的垂直管道组成生产过程中排出的高温烟气进入上部小
Midland-Ross, a division of Ross-Waldron, manufactures an economical regenerative heat exchanger with the ability to recover heat from high-temperature flue gas and allow it to be hot-cooled The advantages of air and furnace flue gas. This is a fluidized bed type heat exchanger, which is a cylindrical tower with a thermal insulation (as shown in the figure). The tower consists of two parts. Each room has several layers of drilled horizontal discs. Tower diameter of 1.8 to 3.6 meters, about 7.6 to 15 meters high, to meet the needs of a variety of cold and flue gas volume. The auxiliary equipment consists of a pneumatic system that conveys the heat exchange medium (ie, high alumina pellets) from the bottom of the tower to the top and consists of a pneumatic pump and a vertical pipe near the tower to form the high temperature flue gas discharged during production into the upper small
