Hydrogen-rich gas generator

Abstract

A process and apparatus is described for producing a hydrogen rich gas by introducing a liquid hydrocarbon fuel in the form of a spray into a partial oxidation region and mixing with a mixture of steam and air that is preheated by indirect heat exchange with the formed hydrogen rich gas, igniting the hydrocarbon fuel spray mixed with the preheated mixture of steam and air within the partial oxidation region to form a hydrogen rich gas. The apparatus for performing the process is in the form of a bell-shaped chamber which consists of an open cylinder wherein a partial oxidation reaction takes place. An air pasageway and a pipe for injecting water into the passageway are provided for forming a steam-air mixture. The air is preheated indirectly by the heat generated as a result of igniting a hydrocarbon fuel spray and thus the water is converted into steam when injected into the preheated air. The air-steam mixture is then conducted through a region of the hydrogen generator where a plurality of pipes are spaced and arranged to provide a heat exchange baffle. These pipes conduct the hydrogen rich gas after it has been generated in the open cylinder.
