A method for the treatment of fly ash in a waste incineration plant with liquid slag discharge opening and system for executing the method

摘要

After the fly ash is removed from the flue gases by a separator, it is introduced into a combustion chamber which may be either the primary combustion chamber of the furnace or a separate chamber in a secondary combustion chamber. There, it is burned until only the liquid slag remains and then removed, along with the other liquid slag formed in the furnace by the primary combustion process. Various methods and apparatus are described for carrying out the introduction of the fly ash into the combustion chamber. They include: packing the fly ash into separate metal containers to be introduced into a rotating primary combustion chamber of the furnace; mixing the ash with fuel and introducing it into the furnace through a lance; forming the ash into pellets and introducing the pellets into the furnace; blowing the ash through an air lance into the output end of the furnace and into the molten slag therein; and, blowing the ash through an air lance into a separate combustion chamber in the secondary combustion chamber of the incinerator.
