摘要: In a process of thermally treating fine-grained solids, the latter are preheated in a plurality of heat exchange stages by means of exhaust gases flowing in two parallel exhaust gas lines and are subsequently heated only by exhaust gases from a furnace and are then fed to the reaction vessel and subsequently to the furnace. The two exhaust gas streams are supplied with a mixture of exhaust gases from the furnace and exhaust gases from the reaction vessel. To permit different condition in the heat exchange stages associated with the two exhaust gas lines to be taken into account, two partial streams of exhaust gases are withdrawn from the reaction vessel and supplied to respective ones of the exhaust gas lines. Two partial streams of exhaust gases from the furnace are admixed to respective ones of said partial exhaust gas streams from the reaction vessel.

摘要: 在细颗粒物料热处理的一套工艺中,被处理的物料先经过一次多级热交换,在两条平行的废气管道中进行预热,然后经过加热炉的废气气流单独进行加热,送入反应器中,再送入加热炉,在加热过程中,两条废气管道又经来自加热炉的废气和来自反应器的废气的混合气体进行加热。为了便于考虑两条废气管道中的条件的差异,将来自反应器的废气分成两股,分别送入两条废气管道,在来自反应器的两股气流中又分别加进来自加热炉的废气。
