摘要:
A steam generator system incorporates multiple processes, either in series or independently and with each process having a process fluid associated therewith, to transfer heat between a common working fluid and the process fluids in order to generate steam from the working fluid. The heat transfer may be controlled by controlling the flow of the working fluid to further regulate and control the generation of steam and/or the individual processes themselves. The generator system includes a vessel and may optionally have baffles located within the vessel to separate the flow of working fluid into a recirculation system to facilitate in the overall operation of the system. The working fluid must be capable of forming steam and preferably consists essentially of water. Straight tubes, plate-type heat exchange surfaces having a common boiling fluid stream, U-tubes, helical tubes, and/or curved tubes may be used as heat exchange means for transferring heat between the working fluid and the process fluids.

An auto-thermal reformer assembly is provided having a plurality of self-contained reformer modules positioned within a pressure vessel. The reformer modules each contain catalyst for inducing reforming reactions to produce hydrogen rich gas. At least one heat exhanger is provided for transferring heat from the hydrogen rich gas to the reactants entering or inside of the pressure vessel.

A thermally integrated burner/emitter/recuperator (BER) for a thermophotovoltaic (TPV) electric generator achieves improved energy efficiency using either liquid or gaseous fuels. A mixed ceramic and metallic alloy heat exchanger, together with a high temperature emitter, achieves increased energy density in a compact and lightweight assembly.
