Are recuperators always great?
01/31/2011
Recuperators have been used by a number of manufacturers to increase their gas turbine's efficiency. The recuperator is a heat exchanger that utilizes the gas turbine's hot exhaust air to pre-heat the combustion air. If done properly, theoretical efficiency improvements up to 20% are possible over a wide operating range.
