Abstract
A gas turbine engine combustor includes a gas-turbine-engine-combustor outer annular case and a gas-turbine-engine-combustor premixer tube. The outer annular case has a longitudinal axis. The premixer tube has an entrance, an exit, and a centerline. The premixer tube is adapted to receive fuel-injector-discharged fuel. The entrance is adapted to receive at least some compressor-discharge air. The exit is located inside the outer annular case. At the exit the centerline points in a direction which is more perpendicular to, than parallel to, the longitudinal axis. In one example, the combustor is a straight-flow combustor. In a different example, the combustor is a reverse-flow combustor.
Description
- The present invention relates generally to combustors, and more particularly to a gas turbine engine combustor.
- Conventional gas turbine engine combustors have outer and inner annular cases, outer and inner liners (with air dilution holes) located radially between the outer and inner annular cases, a combustor dome connecting the outer and inner liners, and circumferentially arrayed premixer tubes each having an entrance and an exit. Each premixer tube is adapted to receive fuel-injector-discharged fuel, the entrance is adapted to receive at least some compressor-discharge air, and the exit is aligned to axially deliver such fuel-air mixture for ignition in the combustor. The combustion gases power a downstream turbine which rotates the compressor. Straight flow and reverse flow combustors are known. Gas turbine engines have been used to power aircraft, ships, etc.
- Still, scientists and engineers continue to seek improved gas turbine engine combustors.
- A first expression of a first embodiment of the invention is a gas turbine engine combustor including a gas-turbine-engine-combustor outer annular case and a gas-turbine-engine-combustor premixer tube. The outer annular case has a longitudinal axis. The premixer tube has an entrance, an exit, and a centerline. The premixer tube is adapted to receive fuel-injector-discharged fuel. The entrance is adapted to receive at least some compressor-discharge air. The exit is located inside the outer annular case. At the exit the centerline points in a direction which is more perpendicular to, than parallel to, the longitudinal axis.
- A second expression of a first embodiment of the invention is a gas turbine engine combustor including a straight-flow-combustor outer annular case and a gas-turbine-engine-combustor premixer tube. The outer annular case has a longitudinal axis. The premixer tube has an entrance, an exit, and a centerline. The premixer tube is adapted to receive fuel-injector-discharged fuel. The entrance is adapted to receive at least some compressor-discharge air. The exit is located inside the outer annular case. At the exit the centerline points in a direction which is more perpendicular to, than parallel to, the longitudinal axis. The direction is angled between generally sixty degrees and generally eighty degrees away from the longitudinal axis.
- A first expression of a second embodiment of the invention is a gas turbine engine combustor including a reverse-flow-combustor outer annular case and a gas-turbine-engine-combustor premixer tube. The outer annular case has a longitudinal axis. The premixer tube has an entrance, an exit, and a centerline. The premixer tube is adapted to receive fuel-injector-discharged fuel. The entrance is adapted to receive at least some compressor-discharge air. The exit is located inside the outer annular case. At the exit the centerline points in a direction which is more perpendicular to, than parallel to, the longitudinal axis. The direction is angled between generally sixty degrees and generally eighty degrees away from the longitudinal axis.
- In one example of any expression of any embodiment of the invention, use of a premixer tube whose centerline, at the exit of the premixer tube, points in a direction more perpendicular to, than parallel to, the longitudinal axis of the gas-turbine-engine-combustor outer annular case creates a swirled flow from the exit of the premixer tube. In this example, such swirled flow results in a shorter and simpler combustor design with fewer swirlers, lower soot, lower carbon monoxide, lower NOx, a greater turndown (e.g., 20:1), an excellent pattern factor (e.g., less than 0.20), and a lower cost compared to the axial flow from the exit of a premixer tube of a conventional gas-turbine-engine combustor.
