摘要:
In the method according to the invention for increasing the calorific value of a material flow containing carbon, preferably a material flow of renewable raw materials, the material flow is brought in direct contact with at least one low-oxygen, inert hot gas flow in a reactor, wherein the hot gas flow is formed at least 50%, preferably at least 80%, by exhaust gas of a process for thermally processing cement raw meal and/or lime and/or an ore, wherein at least part of a preheater exhaust gas for preheating the cement raw meal and/or lime and/or ore is used as the hot gas flow.
摘要:
The system according to the invention for the thermal treatment of a material flow, preferably a material flow containing carbon, comprises a multiple-story furnace having at least one upper and one lower process chamber, which are isolated from each other in regard to gas flow and which each comprise at least two stories arranged one above the other, wherein the at least one upper process chamber is designed for the heat treatment of the material flow at elevated temperatures and the lower process chamber is designed as a cooling zone, wherein the cooling zone has means for feeding liquid coolants, e.g., an injection of water, for cooling and creating an inert atmosphere.
