摘要： Disclosed is an air-assisted simplex spray nozzle assembly for a fuel burner that includes, inter alia, a nozzle body that has opposed upstream and downstream ends, wherein the downstream end of the nozzle body defines a fuel outlet, an adapter member that is engaged with the upstream end of the nozzle body and defines concentrically positioned air and fuel inlets for the nozzle assembly and an air cap that is positioned over the downstream end of the nozzle body. The nozzle assembly further includes a fuel circuit and a first air circuit. The fuel circuit directs fuel from a fuel pump toward the fuel outlet of the nozzle body. The fuel circuit extends from the fuel inlet of the adapter member through the nozzle body to the fuel outlet. The first air circuit directs assist air towards the fuel exiting from the fuel outlet. The first air circuit extends from the air inlet of the adapter member, through a gap defined between the air cap and the nozzle body and merges with the fuel emitted from the fuel outlet of the nozzle body. In certain embodiments, the assist air is provided to the first air circuit by an auxiliary pump.

摘要： A simplex air blast fuel injection system and method for the atomization of fuel for ignition to drive a gas turbine includes a simplex nozzle which receives a fuel from a fuel pump powered by the turbine over a range of pressures between maximum and minimum pressures during the operation of the turbine, and also received fuel from the fuel pump at a substantially lower pressure than the minimum fuel pressure when the turbine is cranked during startup. The fuel is discharged from the nozzle orifice as a swirling stream of atomized fuel during turbine operation, and as a film which is insufficiently atomized to initiate ignition during the turbine startup. An air compressor is also powered by the turbine to supply air at a low pressure and high volume to the fuel issuing from the nozzle orifice during both turbine operation and startup. An air director shroud imparts a swirling motion to the low pressure, high volume air and directs the swirling air to adjacent the fuel film as it issues from the nozzle orifice during startup to produce a pressure differential between opposite sides of the film to explode and atomize the fuel film sufficiently to permit initiation of ignition during turbine startup. A stream of low pressure, high volume air is also directed to the swirling stream of atomized fuel during turbine operation and that air stream is also preferably swirling air.
