COMBUSTOR HAVING DILUTION COOLED LINER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17932806 titled 'COMBUSTOR HAVING DILUTION COOLED LINER
Simplified Explanation
The patent application describes a combustor for a gas turbine that includes a liner with an upstream and downstream portion.
- The upstream portion has an outer shell, a heat shield panel, and a baffle cavity in between.
- The outer shell has a cooling opening to provide compressed air to the baffle cavity.
- The heat shield panel has a cooling opening at its downstream end.
- A fence is placed downstream of the heat shield panel cooling opening and extends into the combustion chamber.
- The heat shield panel cooling opening allows compressed air to flow through it from the baffle cavity to cool the heat shield panel and partially dilute combustion gases in the combustion chamber.
Original Abstract Submitted
A combustor for a gas turbine has a combustor liner including an upstream liner portion, and a downstream liner portion. The upstream liner portion includes an outer shell and a heat shield panel, with a baffle cavity therebetween. The outer shell includes an outer shell cooling opening for providing a flow of compressed air to the baffle cavity, and the heat shield panel includes a heat shield panel cooling opening at a downstream end of the heat shield panel. A fence is arranged at a downstream side of the heat shield panel cooling opening and extends beyond a hot side surface of the heat shield panel into a combustion chamber. The heat shield panel cooling opening provides a flow of the compressed air therethrough from the baffle cavity for cooling of the heat shield panel and for providing at least partial dilution of combustion gases within the combustion chamber.
