Abstract

In a base part (1) of a plant in the basic materials industry, hot exhaust gases occur during a first phase (P I) of a plant cycle. In a second phase (P2) of the plant cycle, the hot exhaust gases do not occur or only to a considerably reduced extent. The hot exhaust gases are removed f m the base part (1) by way of a pipeline System (2) and discharged to the outside air. At least in the first phase (PI), molten salt is removed from a first tank vessel (7) and used for the direct or indirect cooling of a first portion (5) of the pipeline System (2). The heated-up molten salt (6) is fed to a second tank vessel (8). In a second portion (9) of the pipeline System (2), which is arranged downstream of the first portion (5), the pipeline System (2) is cooled with water. In an evaporator (13), water is evaporated, in a superheater (14) the steam is superheated and then the steam is fed to a load device (15). After that, the steam is Condensed into water and is preheated again. At least the feeding of the steam to the load device (15) takes place continuously. For the superheating of the steam, at least in the second phase (P2), the molten salt (6) is removed from the se cond tank vessel (8), fed to the superheater (14) and then fed to the first or a third tank vessel.
