Abstract
The invention relates to a steam generator (,) for superheated steam for incineration plants with corrosive flue gases, essentially comprising a radiation section (,) and a convection section (,), having at least one superheater (,) and having plates (,) arranged on the inside of at least one wall (,) of the radiation section (,), a space (,) being provided between the plates (,) and the wall (,) of the radiation section (,), and at least part of the superheater (,) being arranged as a wall superheater (,) in the space (,) in the radiation section (,). The steam generator is distinguished by the fact that the space (,) contains a noncorrosive gaseous atmosphere which is at a higher pressure than the pressure of the gases in the combustion chamber (,). In this way, it is possible to reach a high superheater temperature without corrosion to the final superheater, so that the superheater can be made from inexpensive material.
