In a downhole steam generator, hydrogen, oxygen, and water are separately injected into an oil well. The hydrogen and oxygen are made to react, either with the aid of a catalyst or due to an electric spark. Heat from the reaction converts the water in the area into steam, which is then used to enhance the production of the oil well. The hydrogen may be produced at the surface of the well by the steam reforming of a hydrocarbon. The hydrogen injected into the well may be provided as part of a reformate mixture produced by the steam reforming process. The water is preferably atomized by the stream of oxygen immediately before ignition, so as to provide a maximum surface area for heat absorption.

What is claimed is: 1. An atomizer for use in mixing hydrogen, oxygen, and water downhole in an oil well, comprising: a) an upper section comprising an entry duct in fluid communication with a chamber formed in the upper section, the chamber having an upper interior surface, the upper interior surface being generally flat, the chamber also including an outlet hole, b) a lower section comprising a lateral entry duct and an axial duct, and an annular space surrounding the axial duct, wherein the lateral entry duct is in fluid communication with the annular space, the lower section including a male threaded member, the male threaded member having a forward end surface, the forward end surface being generally flat, wherein the upper and lower sections are screwed together such that the forward end surface of the male threaded member and the upper interior surface of the upper section are spaced apart to form a small gap. 2. The atomizer of claim 1, wherein the gap has a size in a range of about 0.001-0.003 inches. 3. An atomizer for use in mixing hydrogen, oxygen, and water downhole in an oil well, comprising: an entry duct in fluid communication with a chamber, the chamber having a gap defined by a pair of generally flat, spaced apart surfaces, the chamber also having an outlet hole, the entry duct comprising means for introducing water into the chamber, and means for directing oxygen towards the chamber so as to atomize water entering through said entry duct, and means for separately directing hydrogen towards said outlet hole. 4. The atomizer of claim 3, wherein the gap has a size in a range of about 0.001-0.003 inches.
