Abstract
A process for heat-treating refuse comprising the steps of decomposing in a combustion furnace a quantity of refuse into slag, emitted gas and fly dust. The fly dust is separated into a fine dust fraction and a coarse dust fraction. The coarse dust fraction is fed back to the combustion chamber, and the fine dust fraction is treated for removal of desired constituents.
