ABSTRACT:
Combustion fuel stream supply systems for use with pressure swing adsorption (PSA) assemblies, and hydrogen-generation assemblies and/or fuel cell systems containing the same. The PSA assemblies are operated according to a PSA cycle to receive a mixed gas stream and, while producing a product hydrogen stream therefrom, intermittently discharge a byproduct stream. The byproduct stream, when available, may be delivered as a fuel stream to a heating assembly, which may heat the hydrogen-producing region that produces the mixed gas stream. A combustion fuel stream supply system selectively supplies an auxiliary fuel stream when a byproduct stream is not discharged or otherwise does not have a predetermined combustion fuel value sufficient, when combusted, to maintain the hydrogen-producing region within a desired temperature range. The one or more streams supplied to the heating assembly have a combined combustion fuel value at least as great as the predetermined threshold value.
