Abstract
A conventional steam power plant or a combined power plant is provided with intermediate superheating. At least part of the superheated steam in the superheater (3) and the intermediately superheated steam in the intermediate superheater (9) are subject to an indirect heat exchange. The device is characterized in that the superheater (3) and the intermediate superheater (9) are provided with at least one mutual superheater/intermediate superheater heat exchanger unit (19). The unit (19) includes, for example, a double-walled pipe (21) whose inner pipe is provided for the superheater steam flow, and whose outer pipe is provided for the intermediate superheater steam.
