Refroidissement de l'air à l'entrée d'une turbine à combustion : avantages et options techniques dans les applications énergétiques urbaines.

Combustion turbine inlet air cooling: benefits and technology options in district energy applications.

Auteurs : ANDREPONT J. S.

Résumé

The paper presents the concepts and benefits of cooling the inlet air entering CTs (combustion turbines) during times of high ambient air temperature. Actual examples are presented of CTIAC (combustion turbine inlet air cooling) in district energy applications, illustrating the various technologies. During hot weather, CTIAC can typically achieve a CT power output improvement of 20 to 30%, as well as an efficiency improvement of 5%. CTIAC unit capital costs are often roughly half those of equivalent simple cycle CTs. Further enhanced cost benefits are described that are achievable when CTIAC is coupled with district cooling systems. CTIAC is projected to be of increasing value in future deregulated electric power environments.
