Gas turbine with heat recovery generator of superheated steam for injecting into the combustion chamber and of saturated steam of cooling then injecting into the combustion chamber

摘要

The heat recovery process involves producing superheated steam (21) in an exhaust heat steam generator (14). This steam is introduced into the high-pressure combustion chamber of the gas turbine group. Saturated steam is taken from a drum (28) of the exhaust heat steam generator via closed flow paths (22a/23a, 22b/23b, 22c/23c, 22d, 23d) and sent through the components (2, 3, 4, 5) of the gas turbine group which require cooling.
