Thermally integrated heat exchange system for solid oxide electrolyte systems

摘要

A thermally integrated heat exchange system for solid oxide electrolyte systems includes a thermally insulated furnace enclosure structure having an internal chamber therein and a plurality of solid oxide electrolyte plates disposed within the internal chamber. A heat exchanger particularly suited for use with the thermally integrated system has gas passageways for the flow of gases therethrough and is associated with the walls of the furnace enclosure. Thermal energy radiated from an operational solid oxide electrolyte system within the furnace enclosure may be used to preheat incoming reactant gases destined for use by the electrolyte plates. Exchange of thermal energy between hot exhaust gases and cooler incoming gases may also occur in the heat exchanger gas passageways that are substantially thermally integrated along their length.
