RESIDUAL GAS HEAT EXCHANGE COMBUSTION-SUPPORTING SYSTEM BASED ON METHANOL-WATER MIXTURE REFORMING HYDROGEN PRODUCTION SYSTEM, AND METHOD THEREOF

摘要

The invention discloses residual gas heat exchange combustion-supporting system based on a methanol-water mixture reforming hydrogen production system and a method thereof, wherein the residual gas heat exchange combustion-supporting system comprises a reformer, a heat exchange tube and an air intake device: the reformer is provided with a reforming chamber, a separating device, a combustion chamber and an exhaust vent, the residual gas produced by the reformer is discharged from the exhaust vent to the first delivery passage of the heat exchange, tube; the heat exchange tube has coaxial double-layer first and second delivery passages. The invention enables to fully reclaim the heat from the residual gas discharged by the reformer, so that the outside air is warmed before entering the reformer, which in turn makes the warmed outside air attain a very good combustion-supporting effect.
