AUTOOXIDATION INTERNAL HEATING TYPE STEAM REFORMING SYSTEM

摘要

An autooxidation internal heating type steam reforming system designed so as to effect autoreforming of raw gas in the presence of oxygen to thereby form a hydrogen-rich reformed gas, comprising steam generating means (2) for heatin g water with combustion gas produced at combustion section (2a) to thereby generate steam, first suction mixing means (4) for introducing raw gas into steam stream by suction to thereby obtain a raw material/steam mixture, and reforming means (1) for oxidizing the raw gas contained in the raw material/steam mixture with oxygenic gas fed from outside to thereby carry o ut steam reforming of the raw gas with heat of oxidation reaction. The reformed gas is fed to fuel cell (300). Any anode waste gas is recycled as fuel for t he steam generating means and/or the raw gas.
