An airflow system for a gas turbine system (12) according to an embodiment includes: a compressor component (18) of a gas turbine system (12); an airflow generation system for attachment to a rotatable shaft (24) of the gas turbine system (12), the airflow generation system and the compressor component (18) drawing in an excess flow of air (72) through an air intake section (16); 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 airflow generation system and the compressor component (18) 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).
