Abstract: A description is given of a method as well as an apparatus for heat treatment of raw materials such as cement raw meal, limestone or other mineral-containing raw materials, by which method raw material is preheated and possibly calcined in a preheater system (1) and possibly burned in a kiln (8), and where solid and/or liquid fuel is brought into contact with preheated raw material in the presence of steam in a gasification reactor (3) thereby causing the fuel to be fractionated partly into a hydrogen-containing combustible gas which is discharged from the gasification reactor via a gas outlet and partly into carbonaceous solid fuel residues which are discharged from the gasification reactor via a solids outlet. The method and apparatus are characterized in that at least some of the hydrogen-containing combustible gas is utilized for heat treatment of raw material.

Abstract: A description is provided of a method and an apparatus for manufacturing of cement whereby cement raw meal is preheated in a preheater, calcined in a calciner by contact with hot gases which are introduced into the calciner via a gas inlet and being diverted from the calciner via a gas outlet, and where calcined cement raw meal is diverted from the calciner, burned into cement clinker in a kiln and subsequently cooled in a clinker cooler. The method and the apparatus are peculiar in that at least a portion of the calcined cement raw meal diverted from the calciner is heated further in a separate system to a temperature which exceeds the calcination temperature, and being subsequently recirculated to the calciner, and in that at least a portion of the gases which are diverted via the gas outlet of the calciner is removed from the plant with a view to storage in the underground or other additional treatment.
Abstract translation: 提供了一种用于制造水泥的方法和装置,其中水泥生料在预热器中预热,在煅烧炉中通过与通过气体入口引入煅烧炉的热气体接触煅烧并从煅烧炉经由 气体出口,并且煅烧的水泥生料从煅烧炉中转移,在窑中燃烧成水泥熟料,随后在熟料冷却器中冷却。 该方法和设备是特别的,因为从煅烧炉转移的煅烧水泥生料的至少一部分在单独的系统中被进一步加热到超过煅烧温度的温度,随后再循环到煅烧炉中,并且因此 通过煅烧炉的气体出口转移的气体的至少一部分从设备中移出,以便储存在地下或其它附加处理中。
