A combustor includes a first wall, a second wall, an injector grommet, a combustor longitudinal axis, and a connection assembly indirectly connecting the first wall to the second wall. A portion of the injector grommet is disposed within a groove of the connection assembly.

Combustor

A combustor liner assembly includes a liner assembly, including a hot dome, a hot wall, and an impingement shield. The liner assembly further includes a convector assembly. The combustor liner assembly further includes an impingement dome assembly, including a ring-shaped portion defining a plurality of apertures configured to receive a plurality of fuel injectors, and a face. The ring-shaped portion and the face define an annular passage, and the face defines a plurality of apertures and a plurality of orifices. The convector assembly and the impingement dome assembly are operably coupled to one another, and the plurality of orifices of the face are configured such that the hot dome is exposed to air flowing in the annular passage of the impingement dome assembly. The combustor liner assembly is configured to provide flow communication between the annular passage of the impingement dome assembly and the plurality of fuel injectors.

Combustor assembly for gas turbine engine

Many government entities regulated emission from gas turbine engines including CO. CO production is generally reduced when CO reacts with excess oxygen at elevated temperatures to form CO2. Many manufactures use film cooling of a combustor liner adjacent to a combustion zone to increase durability of the combustion liner. Film cooling quenches reactions of CO with excess oxygen to form CO2. Cooling the combustor liner on a cold side (backside) away from the combustion zone reduces quenching. Furthermore, placing a plurality of concavities on the cold side enhances the cooling of the combustor liner. Concavities result in very little pressure reduction such that air used to cool the combustor liner may also be used in the combustion zone. An expandable combustor housing maintains a predetermined distance between the combustor housing and combustor liner.

Combustor for a low-emissions gas turbine engine

Systems for controlling the combustion air to be used with a gas turbine engine for control the products of combustion and reducing emissions emitted therefrom have been used in the past. The present system includes a compressed air plenum being divided into a combustion air supply portion and a dilution or cooling air supply portion. A variable geometry system is positioned between the compressor section and the compressed air plenum. The variable geometry system is movably between an open position and a closed position. Movement of the variable geometry system varies the distribution of the compressed air between the combustion air supply portion and the dilution or cooling air supply portion. The system reduces emissions emitted from the gas turbine engine.

A method of operating a diesel engine assembly having a combustion chamber is disclosed. The method includes the step of determining a desired level of NO.sub.x for exhaust gases exiting the combustion chamber and generating a fuel control signal in response thereto. The method further includes the steps of injecting an amount of combustor fuel into a combustor based on the fuel control signal and combusting the amount of combustor fuel in the combustor so as to produce combustion products. The method yet further includes the steps of advancing the combustion products into the combustion chamber during an intake stoke of the diesel engine and injecting diesel fuel with a fuel injector into the combustion chamber while the combustion products are located in the combustion chamber during a compression stroke. The method still further includes the step of combusting a mixture of the diesel fuel and the combustion products so as to produce exhaust gases during a power stroke. An engine assembly is also disclosed.

An engine is provided having a fuel supply system which includes apparatus of straightforward construction that is powered solely by a flow of fuel through a delivery line to the engine for increasing the flow of fuel through the delivery line to the engine during start-up of the engine. A small control volume of pressurized fuel is stored during a preceding operational period of the engine for use in augmenting the fuel flow to the engine during a subsequent start-up of the engine. A converter apparatus is also disclosed for converting a portion of the fuel flow from the control volume and/or from a main fuel pump into an increased flow rate or pressure of fuel to the engine during the subsequent start-up. The control volume of fuel is stored in such a manner that volume compensation for changes in ambient temperature is provided, and in such a manner that the fuel line is positively shut off during periods of inoperation such that the fuel cannot leak out or evaporate and thus not be available for rapid start-up of the engine during a subsequent start.
