Abstract
An atomizer provides a high-quality fuel-air mixture to a gas turbine engine, by combining air input from an engine compressor and fuel input from a single low-pressure fuel supply pump. The atomizer includes an atomizer body, a main vortex chamber, a secondary vortex chamber for improving quality of the fuel-air mixture, and a fuel sleeve providing fuel to the secondary vortex chamber. The main vortex chamber includes a main outlet nozzle in fluid communication with a combustion chamber inlet of the gas turbine engine. The secondary vortex chamber includes a secondary outlet nozzle in fluid communication with the main vortex chamber. The fuel sleeve has a blind channel with a longitudinal axis and a fuel tip. The same atomizer may be used for startup mode and for all operational modes of the gas turbine engine.

An atomizer providing atomization of a fuel-air mixture flowing into a gas turbine engine, the atomizer receiving air input from an engine compressor and fuel input from a low-pressure fuel supply pump, the atomizer comprising
- an atomizer body,
- a main vortex chamber comprising a main outlet nozzle in fluid communication with
- a combustion chamber inlet of the gas turbine engine;
- a secondary vortex chamber for improving an atomization quality of the fuel-air-mixture, the secondary vortex chamber comprising a secondary outlet nozzle in fluid communication with the main vortex chamber;
- and
- a fuel sleeve providing fuel to the secondary vortex chamber, the fuel sleeve comprising a blind channel with a longitudinal axis and a fuel tip;
- wherein, the atomizer further comprises an air cavity and grooves on a surface of the main vortex chamber which supply air to the air cavity.
