A PROCESS AND INSTALLATION FOR TREATING ORGANIC MATERIAL IN ORDER TO CHANGE IT INTO MINERAL CONDITION, ESPECIALLY FOR TREATING URBAN GARBAGE

摘要

The present invention proposes the change of organic garbage into inorganic matter, which can be used as a fertilizer, in a more efficient and cost effective manner than with the known processes. This object is achieved by a process and an installation in which the organic material is first burned in a furnace (1), the gases and vapors which result from the combustion being then washed in a washer (7, 21). Both the solid residues of combustion in the furnace (1) and the washing medium which has reacted with the gases and vapors in the washer (7, 21) are conducted into a decantation reservoir (17), which can also serve as a source of washing medium for the washer (7, 21), forming a closed circuit.
