Abstract
An apparatus for supplying high pressure atomizing and purging fluid to the fuel system of a gas turbine engine. The apparatus is comprised of a turbocompressor, multiple flow conduits and associated valves and controls. Alternative versions of the fundamental apparatus may include heat exchangers for heating and cooling the atomizing and purging fluid within the apparatus. The apparatus works with all types of gas turbine engine cycles well known to one skilled in the art. The apparatus includes a first conduit for extracting a small percentage of the fluid compressed by the turbine engine compressor, and the first conduit is further divided into second and third conduits for supplying portions of the small percentage of compressed fluid to the turbocompressor compressor and turbine. The portion of the fluid flowed to the turbocompressor compressor is compressed and then flowed to the turbine engine fuel system at a location that enhances atomization of the fuel or purges the fuel from the fuel system nozzle after shut-off. The fluid discharged from the turbocompressor turbine is flowed back to the turbine engine to offset engine efficiency losses. The turbocompressor may be configured in any number of mechanical configurations, familiar to one skilled in the art of turbomachinery.
