Regenerative gas turbine cycle
TLDR
In this article, a regenerative gas turbine cycle in which heat recovery is carried out by a mixture of air/steam which is obtained by contact between water and a part of or the whole of compressed air, is described.Abstract:
In a regenerative gas turbine cycle in which heat recovery is carried out by a mixture of air/steam which is obtained by contact between water and a part of or the whole of compressed air, said compressed air being compressed by a compressor for compressing gas using air or air based gas as a combustion supporting/working medium gas; the improvement comprising: the mixture of air/steam and liquid phase cooled water being obtained through the contact between the compressed air and heated water which is used as heat recovering medium; said cooled water being used as heat recovering medium not only for heat recovery of turbine exhaust gas but also, for (a) intercooling of the compressor, and/or (b) precooling of compressed air for the contact operation; supplying water corresponding to the amount of water which contacts the compressed air and is lost by evaporation to the liquid phase water for contact or heat recovery as it is or after using as a heat recovering medium.read more
