ABSTRACT:
A fuel injection assembly for a combustion chamber of a gas turbine engine is disclosed in which a plurality of premixing chambers are in communication with the combustion chamber and adjacent pairs of the premixing chambers are connected to a single prevapoization chamber by prevaporization conduits. Fuel is injected into the prevaporization chamber via a fuel injector and is mixed with oxidizer passing into the prevaporization chamber such that the fuel/oxidizer mixture has a richness exceeding the stoichiometric ratio. The fuel/oxidizer mixture passes into the prevaporization conduits through a diaphragm opening and, upon entering the premixing chamber, is mixed with additional oxidizer such that the fuel/oxidizer mixture in each premixing chamber has a richness less than the stoichiometric ratio. The premixing chambers are bounded by generally tubular walls, a portion of each adjacent tubular wall forming a protective hood between the fuel injector and the combustion chamber so as to prevent self-ignition of the fuel/oxidizer mixture in the prevaporization chamber. Oxidizer entering the premixing chambers passes through one or more oxidizer swirlers to assure a complete mixing of the fuel and oxidizer prior to its passing into the combustion chamber.
