Abstract
A fuel atomizer for a liquid hydrocarbon fuel reformer/processor creates a high velocity atomized stream of a liquid fuel and steam, wherein the liquid fuel is quickly vaporized so as to limit carbon deposition from the fuel on the fuel vaporizer surfaces. The injector includes a small diameter fuel injection tube through which the liquid fuel and steam mixture is ejected at relatively high velocities. The liquid fuel forms an annular film which surrounds a steam core in the tube, which liquid droplet film and steam core composite are ejected from the tube into a stream of super heated steam, or steam and air. The stream of super heated steam substantially instantaneously vaporizes the fuel droplets from the film after the latter leaves the injection tube.
