Abstract
A turbomachine includes a compressor portion that generates a cooling airflow. The compressor portion includes a plurality of compressor stages. The turbomachine further includes a turbine portion operatively connected to the compressor portion. The turbine portion includes a plurality of turbine stages. A conduit fluidly connects at least one of the plurality of compressor stages with at least one of the plurality of turbine stages and delivers a portion of the cooling airflow from the compressor portion to the turbine portion. An injector port is connected to the conduit and a secondary fluid generation system. The secondary fluid generation system delivers an amount of dry secondary fluid into the cooling airflow passing from the compressor portion to the turbine portion. The amount of dry secondary fluid replaces a portion of the cooling airflow passing to the turbine portion.
