一、序言就焙烧炉的设计演进而言,沸腾焙烧炉系由县浮焙烧炉(?)进而得,主要的分别在於:县浮焙烧炉的气流是(?)上而下;而沸腾焙烧炉的气流,则是自下而上。但是从原理来讲,沸腾焙烧法的理论与县浮焙烧完全不同,现将它的原理简单叙述如下:在一固体层上,使下面空气向上浮起精砂的力量与固体颗粒下落的力量相等,藉空气流量的控制与矿砂加入量的控制使矿(?)在一定时间内,停留在沸腾层内与空气发生焙烧的作用,最后达到去硫的目的。这种方法虽然是最近的发现,但是由於效率很
Preface In terms of the design and development of the roaster, the roasting roaster is derived from the county roasting roaster (?), The main difference being that the airflow of the roasting furnace in the county is (?) Up and down; and the roasting roaster Of the air, it is bottom-up. However, in principle, the theory of boiling roasting is totally different from that of county floating roasting. Now its principle is briefly described as follows. On a solid layer, the force of floating up the air below the fine sand is equal to that of falling solid particles , By controlling the air flow and the amount of ore added to control the mine (?) In a certain period of time, stay in the boiling layer and the role of air roasting, and finally achieve the purpose of desulfurization. Although this method is the most recent discovery, but because of efficiency
