Exhaust gas temperature control device for reducing a temperature of exhaust gases of a gas turbine.

摘要

There is provided an exhaust gas temperature control device (14) for reducing a temperature of exhaust gases. The exhaust gas temperature control device (14) contains a first channel (58) and a Venturi element (60). The first channel (58) is configured to at least a portion of the exhaust gases of a gas turbine (18) to receive. The Venturi element (60) is arranged in the first channel (58) and is surrounded by a flow path (64) traversed in order to receive the exhaust gases in the first channel (58). Through the first channel (58) and the Venturi element (60) extending therethrough, an opening (66, 68) connected to the flow path (64) is in fluid communication, such that the through flow path (64) passing therethrough exhaust ambient air through the opening (66, 68) into the flow path (64) involve, to reduce a temperature of through the first passageway (58) flowing through the exhaust gases.
