POWER GENERATION SYSTEM EXHAUST COOLING

摘要

An airflow control system for a gas turbine system (12) according to an embodiment includes: a compressor component (18) of a gas turbine system (12) for generating an excess flow of air (72); a mixing area (33) for receiving an exhaust gas stream (32) produced by the gas turbine system (12); an air extraction system (70) for extracting at least a portion of the excess flow of air (72) generated by the compressor component (18) of the gas turbine system (12) to provide bypass air; and diverting the bypass air into the mixing area (33) to reduce a temperature of the exhaust gas stream (32); and an exhaust processing system (14) for processing the reduced temperature exhaust gas stream (32).
