Abstract
A steam generator for producing superheated steam in a waste incineration plant, includes a boiler housing having a combustion chamber with walls having an evaporator. The evaporator has tubes carrying water and being acted upon by heat energy released during incineration of waste, for producing superheated steam. A wall superheater for increasing temperature of the superheated steam includes a plurality of tubes in a wall of the boiler housing for carrying superheated steam being protected against flue gas from an incineration process by plate-like elements formed of a corrosion-proof material. The boiler housing includes an evaporator housing section having the water-carrying tubes and a wall-superheater housing section spatially separated from the evaporator housing section and having the superheated steam-carrying tubes. The wall-superheater housing section is movable relative to and disposed downstream of the evaporator housing section in flue gas flow direction.
