Title:
GAS TURBINE
Document Type and Number:
Japanese Patent JP2011137470
Kind Code:
A
Abstract:

To inhibit the deterioration in output efficiency by cooling a combustor while inhibiting a pressure loss of compressed air.

A gas turbine is constructed to obtain a rotary power by supplying fuel to compressed air compressed by a compressor 11 in the combustor 12, burning them and supplying the generated combustion gas to a turbine 13. The gas turbine includes a booster device 41 pressure-raising part of the compressed air compressed by the compressor 11, a combustor cooling device 42 cooling the combustor 12 with the compressed air pressure-raised by the booster device 41, a compressed air circulation line 46 supplying the compressed air cooling the combustor 12 to the casing of the combustor 12, and an exchanger 83 cooling the compressed air pressure-raised by the booster device 41 with supply water returned to an exhaust heat recovery boiler 84.
