Within the known Müller-Kühne process and a corresponding installation, a utilization of a great variety of residual materials can be achieved with optimum process control, both in regard to the production of a raw powder and the fuel, whereby this is made possible in particular in that the raw powder components and the fuel components also are, with respect to the residual materials being used, stored separately, conditioned, and then mixed according to the formulation under strict monitoring. The glue gas is used for preheating the raw powder by adding the cold raw powder to it. This simultaneously removes sticky components from the flue gas. The raw powder preheated in this manner, and also the raw powder or dust recovered in subsequent dedusters are returned to the rotary drum kiln, whereby the solid and other fuels are used and burned with a mutually supportive flame at the opposite end of the rotary drum kiln. |
