Abstract

An apparatus is provided which comprises two burner zones using a single igniter separated by a heat transfer zone for use in low-cost hydrogen generation units. When used in conjunction with a control system which limits the effluent temperature to less than about 700.degree. C., the apparatus can be constructed of materials such as carbon steel and stainless steel rather than more exotic materials. This simplified structure and the use of less exotic materials provides an efficient, low-cost combined partial oxidation reactor for small-scale hydrogen production systems, especially for hydrogen production systems associated with fuel cell operation for the production of electricity.
