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.
Claims17
A liner for a gas turbine combustor, the gas turbine combustor having a flow sleeve disposed around the liner and a transition piece, the liner comprising:
- a cooling sleeve disposed on the liner operable to divide air supplied through cooling holes defined in the flow sleeve and compressed air flowing to a space portion defined between the liner and the flow sleeve, the compressed air having collided against the transition piece.
A flow sleeve for a gas turbine combustor, the gas turbine combustor having a liner disposed in the flow sleeve and a transition piece, the flow sleeve comprising:
- a cooling sleeve disposed on the flow sleeve operable to divide air supplied through cooling holes defined in the flow sleeve and compressed air flowing to a space portion defined between the liner and the flow sleeve, the compressed air having collided against the transition piece.
A gas turbine combustor comprising:
- a liner operable to receive fuel injected from a fuel nozzle of a gas turbine that mixes with compressed air and is burned;
- a flow sleeve disposed around the liner, the flow sleeve having cooling holes defined therein operable to cool the liner when air is supplied through the cooling holes;
- a transition piece operable to transmit and increase transmission speed of gas produced in the liner;
- a perforated sleeve disposed around the transition piece, the transition piece having holes defined therein operable to supply compressed air that collides against the transition piece and flows to a space portion defined between the liner and the flow sleeve;
- and
- a cooling sleeve disposed between the flow sleeve and the liner operable to divide air supplied through the cooling holes of the flow sleeve and compressed air flowing to the space portion, the compressed air having collided against the transition piece.
