ABSTRACT:
In a method of cooling the thermally highly stressed units of a gas turbine, a steam quantity (31, 32) which first of all cools a turbine (3, 5) is used, and then the same steam quantity is directed into a combustion chamber (2, 4). After this combustion chamber has been cooled, this steam quantity is introduced into the burn-out zone of the relevant combustion chamber. In this way, the combustion, designed for low NOx emissions, of the relevant combustion chamber is not affected by this introduction of the steam quantity; furthermore, with this introduced steam quantity, the burn-out zone can be moderated for minimizing the remaining pollutant emissions.
