Superheated steam generator for combustion plants with corrosive gases

摘要

The steam generator comprises a radiation part (2) with combustion chamber (3) and a convection part (5). A chamber (12) is provided between the plates (10) and the adjoining inside wall (9) of the radiation part and contains a non-corrosive gaseous atmosphere (13) which has a higher pressure than the pressure of the gases in the combustion chamber. The plates are made of a non-metal inorganic material and have on their side facing the pipes of the superheater ribs which enclose the pipes at least in part.
