What is Ambient Air Injection

AAI is a GE product, this project is a collaborative development with ourselves providing one of our fleet's GT sites for the installation and implementation and involved the injection of ambient temperature air into GT exhaust stream, before HRSG tube modules during start-up. The aim to cool HRSG inlet temperature to reduce live steam temperature and protect steam drums.

Uniper and GE have a strong history of collaborative project development including global 'first of its kind' installations of VLP, HE and AAI.
