Title:
GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2008/038497
Kind Code:
A1
Abstract:
A gas turbine in which fuel is supplied by a combustor (12) to compressed air, compressed by
a compressor (11), and combusted and rotational power is obtained by supplying the
produced combustion gas to a turbine (13). The gas turbine has a pressure raising
device (41) for raising the pressure of a portion of the air compressed by the compressor
(11), a combustor cooling device (42) for cooling the combustor (12) by the compressed
air raised in pressure by the pressure raising device (41), and a compressed air
circulation line (46) for supplying the compressed air, having cooled the combustor
(12), to a wheel chamber of the combustor (12).The combustor can be cooled with
the pressure loss of compressed air suppressed, and this minimizes a reduction
in output efficiency.
