Abstract
A system for retro-fitting a simple gas turbine to convert it to a regenerative gas turbine, the system comprising connector and inner housings associated with the combustors and connected to an air heater.
Claims8
Regenerative system for a gas turbine, wherein the turbine has a single shaft on which are mounted a compressor section and a work section, comprising:
- (a) an air heater mounted adjacent the exit of the work section, the hot exit gas and pressurized air passing through passages formed in the air heater,
- (b) a plurality of combustor housings surrounding the compressor section, each containing a combustor mounted within it and extending coaxially thereof, each combustor having a transition section extending to the entrance to the work section,
- (c) an annular connector housing extending between the combustor housing and the exit of the compressor section to carry the compressed air radially,
- (d) an outer duct leading from the connector housing to one end of the air heater,
- (e) an inner duct attached to the other end of the air heater, and
- (f) an annular inner housing lying within the connector housing, the inner duct being connected to the said inner housing to deliver heated compressed air to the combustor housing, wherein each combustor extends through the inner housing on its way to the entrance to the work section, a seal extends around the combustor where it emerges into the connector housing, and a seal extends between each combustor housing and the inner housing, the connector housing and the outer duct being formed of low temperature steel.
