  • Liner, flow sleeve and gas turbine combustor each having cooling sleeve
    Patent number: 10094573
    Abstract: A gas turbine combustor includes a liner and a transmission piece. Fuel injected in the liner from a fuel nozzle of a gas turbine mixes with compressed air. High temperature gas produced in the liner is transmitted through the transmission piece. The liner is disposed in a flow sleeve in which cooling holes are formed. The transition piece is disposed in a perforated sleeve. Compressed air supplied through holes formed in the perforated sleeve collides with the transition piece. The liner includes a cooling sleeve disposed thereon that divides the air supplied through the cooling holes of the flow sleeve and the compressed air flowing to a space portion between the liner and the flow sleeve.
