Innovation in Turbine Inlet Conditioning

摘要

Many GE Aeroderivative gas turbines are frequently needed to perform on the hottest days to provide peak power. Unfortunately, as the inlet air temperature to a turbine goes up, the power it can generate goes down. This has driven the need for inlet-chilling systems. In response to customers seeking more power with less variations due to ambient effects, GE Energy has teamed with Energy Concepts, Nooter/Eriksen and The Industrial Co to design, build and supply an inlet air chilling unit that utilizes an ammonia-based absorption refrigeration cycle which recovers the exhaust heat from a gas turbine as the heat source. The system can produce chilled air during unit startup so that more power can be produced faster than existing mechanical systems. The sound principles that constitute the basis of the system have enabled the first unit launch and has generated a robust market interest.
