METHOD AND APPARATUS FOR THE POLLUTANT-FREE DISPOSAL OF NOXIOUS AND WASTE MATERIALS WITH A LOW CALORIFIC VALUE, ESP. REFUSE, BY BURNING

摘要

A method and apparatus for the removal of hazardous and waste materials of low heat content, for example, refuse, by means of combustion wherein the combustion process is carried out in a furnace by the presence of added hot combustion air at a temperature sufficient so that the combustion and/or flue gas temperatures are at least 1250 DEG C. In a preferred embodiment of the invention, the combustion process is combined with a process for the production of cement clinker and carried out parallel to the same, wherein air at about 800 DEG C. is branched off for combustion of the hazardous substances from the cooler air of the cement clinker installation and introduced into the furnace. The hot flue gas of the combustion in the furnace is directed into the cement clinker installation. The invention further contemplates that calcium-containing carbonate carriers can be added to the refuse.
