METHOD OF TREATING SOLID MATERIAL AT HIGH TEMPERATURES

摘要

The present invention relates to a method of treating solid materials, such as wastes and biological sludges at a high temperature and of recovering heat from said treatment process, and of cooling the generated process gases, in which method wastes are treated at a high temperature by grate incineration, and the generated heat is used for the production of high temperature superheated steam in a separate cooler for circulating material.
