Humid Air Injection Power Augmentation Technology Has Arrived

This paper presents the latest information on Humid Air Injection (HAI) power augmentation technology for Combustion Turbine and Combined Cycle power plants. It describes: a) The summary of the latest activities on the implementation of HAI and Dry Air Injection (DAI) technologies including results of the validations tests conducted on the PG7241 (FA) combustion turbine, and findings of various CT-HAI implementation projects; b) The technical background including the latest CT-HAI and CT-DAI concepts resulting on the performance improvements and reduced emissions; and c) The novel concept for humidification of the injected air that further reduces overall capital costs by 15%.Copyright © 2003 by ASME
