摘要： A cooler for cooling particulate material which has been subjected to heat treatment in an industrial kiln, such as a rotary kiln for manufacturing cement clinker, which cooler comprises an inlet, an outlet, end walls, side walls, a bottom and a ceiling, at least one stationary supporting surface for receiving and supporting the material to be cooled, means for injecting cooling gas into the material, as well as a reciprocating scraper system which comprises a number of rows of scraper elements arranged transversely across the direction of movement of the material, said scraper elements being moved back and forth in the direction of movement of the material for conveying the material forward across the supporting surface. The cooler is peculiar in that each of the transverse scraper elements is firmly fixed to at least one drive plate oriented in the direction of movement of the material, said plate extending at least across the entire length of the supporting surface, and being led either through the supporting surface of the cooler, its ceiling, one of its side walls and/or at least one of its end walls, where the drive plate is connected to a drive arrangement for movement back and forth.
摘要翻译： 用于冷却在工业窑中进行热处理的颗粒材料的冷却器，例如用于制造水泥熟料的回转窑，该冷却器包括入口，出口，端壁，侧壁，底部和顶板， 用于接收和支撑待冷却材料的至少一个固定支撑表面，用于将冷却气体注入到该材料中的装置，以及一个往复式刮刀系统，该系统包括沿横向跨越材料运动方向布置的多排刮板元件 所述刮刀元件沿用于将材料向前穿过支撑表面输送的材料的运动方向来回移动。 冷却器是特别的，因为每个横向刮刀元件牢固地固定到至少一个在材料运动方向上定向的驱动板，所述板至少延伸穿过支撑表面的整个长度，并且被引导通过 冷却器的支撑表面，其天花板，其侧壁中的一个和/或其端壁中的至少一个，其中驱动板连接到用于前后运动的驱动装置。

摘要： Sulfur oxides are removed from a preheater waste gas stream by reacting the sulfur oxides with lime recovered from the off gas stream in a calcining furnace. The method is particularly adaptable for use in a cement manufacturing plant wherein the sulfur dioxides in the waste gases result from the combustion of fossil fuels used for process heat.
