摘要： A fuel delivery apparatus is provided for a gas turbine engine. This fuel delivery apparatus includes a fuel injector. The fuel injector includes a plurality of fuel passages, a guide passage, a plurality of air passages, a mixing cavity and a fuel injector outlet. The fuel passages extend along an axis to the guide passage. The fuel passages converge radially inwards towards the axis as the fuel passages spiral about the axis towards the guide passage. The guide passage turns radially outwards away from the axis as the guide passage extends from the fuel passages to the mixing cavity. The air passages converge radially inwards towards the axis as the air passages extend axially to the mixing cavity. The mixing cavity fluidly couples the guide passage and the air passages to the fuel injector outlet.

摘要： Burner tubes for gas grills are disclosed. An example burner tube includes an open front end, a closed rear end located opposite the open front end, opposing upper and lower surfaces extending between the open front end and the closed rear end, opposing right and left side surfaces extending between the upper surface and the lower surface and between the open front end and the closed rear end, and a hollow interior defined by the upper surface, the lower surface, the right side surface, and the left side surface. The hollow interior has a rectangular cross-sectional profile that tapers in a direction moving from the open front end toward the closed rear end. The burner tube further includes a plurality of gas ports extending upwardly from the upper surface, with each one of the gas ports having an exit opening raised above the upper surface.

摘要： A combustion system includes a distal flame holder, a pilot fuel distributor, a main fuel distributor, an oxidant source, an array of sensors, and a controller. The oxidant source outputs an oxidant. The pilot fuel distributor supports a pilot flame configured to preheat the distal flame holder by outputting a pilot fuel at least when the combustion system is in a preheating state. The main fuel source outputs a main fuel in the standard operating state. The distal flame holder is configured to support a combustion reaction of the main fuel and the oxidant in the standard operating state. The sensors are configured to sense parameters of the pilot flame and the distal flame holder and to output sensor signals to the controller. The controller executes software instructions that include adjusting the flow of the main fuel, the pilot fuel, and the oxidant responsive to the sensor signals.

摘要： An engine can utilize a combustor to combust fuel to drive the engine. A fuel nozzle assembly can supply fuel to the combustor for combustion or ignition of the fuel. The fuel nozzle assembly can include a swirler and a fuel nozzle to supply a mixture of fuel and air for combustion, which can supply a primary fuel supply and a secondary fuel supply. Increasing efficiency and reducing emission require the use of alternative fuels, which combust at higher temperatures or burn at faster burn speeds than traditional fuels, requiring improved fuel introduction without the occurrence of flame holding or flashback.
