Abstract (en)

[origin: WO2021099597A1] In a waste heat recovery installation (9.1) for utilising thermal energy recovered from exhaust gas streams for power generation by means of steam in a steam power station the object is to create a solution by which the net efficiency of a waste heat recovery installation can be improved when thermal energy recovered from exhaust gas streams is utilised for power generation by means of steam in a steam power station. Acccording to the invention, this is achieved in that the waste heat recovery installation (9.1) comprises at least two steam-generating heat exchangers (1, 5; 3, 6) through each of which two exhaust gas streams (10a, 10b) flow which are separated from one another, said heat exchangers being integrated on the steam side into a common water-steam circuit (15) of the steam power station. One of the two exhaust gas streams (10b) flows through at least one heat exchanger which is designed as a high-pressure heat exchanger (5) or as a medium-pressure heat exchanger or as a low-pressure heat exchanger (6), and the other one of the two exhaust gas streams (10a) flows through at least one heat exchanger which is designed as a high-pressure heat exchanger (1) and on the steam side is connected by a line to the high-pressure heat exchanger (5) through which one exhaust gas stream (10b) flows, or the heat exchanger is designed as a medium-pressure heat exchanger and on the steam side is connected by a line to the medium-pressure heat exchanger through which one exhaust gas stream (10b) flows, or the heat exchanger is designed as a low-pressure heat exchanger (3) and on the steam side is connected by a line to the low-pressure heat exchanger (6) through which one exhaust gas stream (10b) flows.
