Title:
METHOD AND APPARATUS FOR INCINERATION OF COMBUSTIBLE WASTE
Document Type and Number:
WIPO Patent Application WO/2005/108892
Kind Code:
A1
Abstract:
Described is a method as well as an apparatus for incineration of combustible waste during the manufacture of cement clinker by which method the waste is introduced via a waste inlet (11) and supported on a supporting surface (21) incorporated in a separate compartment (9), where the waste being actively transported, while simultaneously subjected to incineration, through the compartment to its outlet (23), where the hot exhaust gases produced in connection with the incineration of the waste being vented to the preheater system for heating the cement raw meal, and where the slag generated during the waste incineration process being extracted from the compartment (9). The method and the apparatus are peculiar in that exhaust gases containing NOx are introduced to the compartment (9).
