POWER STATION AND RELATED STARTING METHOD

摘要

PROBLEM TO BE SOLVED: To find a technique, in which a recuperator is preheated without causing risks of critical locally heated portion of a recuperator for a power station, having at least one turbo-group and one recuperator. SOLUTION: A power station (1) includes: at least one turbo-group (2) comprising at least one turbine (3) and at least one main burner (5) arranged on the upstream of the turbine (3); at least one recuperator (11) located in a first flow passage (15) leading gas to the turbo-group (2) on the one hand and a second flow passage (12) leading gas away from the turbo-group (2) on the other hand; and at least one auxiliary burner (19) located at the outside of the second flow passage (12) and the outlet side of which is connected to the second flow passage (12) at the recuperator (11) or at the upstream of the recuperator.
