Abstract
In a steam generator having a convective part arranged downstream of the furnace chamber and essentially consisting of final superheater (1), pre-superheater, evaporator and economizer connected in series on the flue-gas side, a further contact heat exchanger (5) having a plurality of tube banks (10) is arranged upstream of the final superheater (1). This contact heat exchanger (5) is connected to the steam drum (6) in such a way that it can be operated as both an evaporator and a superheater. The working medium to be heated flows in parallel from the bottom to the top through the tube banks (10), as a rule arranged vertically or inclined, of the contact heat exchanger in the evaporator circuit and flows in series through said tube banks (10) of the heat exchanger in the superheater circuit.
