    • PURPOSE:To provide a stable combustion characteristic and enable a uniform heating to be carried out by a method wherein a nozzle of a combustion unit is divided into a nozzle for air, a nozzle for hydrocarbon and a nozzle for cell discharged gas and then the nozzle for hydrocarbon is filled with a modifying catalyst. CONSTITUTION:During operation, fuel and air preheated at 400 deg.C to 500 deg.C. Cell discharged gas passes through a cell discharged gas flow passage, and air passes through an air flow passage 6, respectively and then injected out of nozzles. Methane active as auxiliary fuel is mixed with steam and passes through a hydrocarbon flow passage 4, and is brought into contact with a modifying catalyst 7 so as to start a reaction. The gas is improved to generate hydrogen having a better combustion characteristic, so that its combustion characteristic is remarkably improved. Then, in case of starting operation, the fuel is not preheated and no steam is generated, so that a combustion is carried out only with methane. Since the nozzle 1 for hydrocarbon and the nozzle 3 for air are arranged with the nozzle 2 for discharged gas being held therebetween, so that the fuel is preheated, and the combustion is gradually carried out at the same time as that of operation.

    • PURPOSE:To enable combustion gas providing a stable combustion and even in case of different type of fuel and having less difference in temperature distribution to be generated by a method wherein natural gas flows in a central port, anode discharged gas flows in a port around it and air flows in the outer- most circumference for a structure having triple ports. CONSTITUTION:Air 22 flows into an air manihold 12 and is injected from an air inlet 15 into furnace and at the same time natural gas 23 flows into a natural gas manihold 14, the gas is injected from a natural gas port 17 into the furnace so as to perform a combustion therein. Heated item is heated and its temperature is increased. Quality of water vapor is improved and generated hydrogen is supplied to an anode of a cell anode discharged gas 24 including unreacted hydrogen is discharged from the anode and a flow rate of natural gas 23 is throttled in place of supply of the anode discharge gas to the burner 1, and then a combustion at the burner 1 is transferred from a combustion of natural gas 23 to a combustion of the anode discharged gas 24. The anode discharged gas 24 is injected from an anode discharged gas port 16 into the furnace. Simultaneously, a flow rate if air 22 is also controlled and an adjustment is carried out so as to prevent a flame length from being too elongated.

    • PURPOSE:To provide a hydrogen production device capable of producing high-purity hydrogen by carrying out each reaction in a modifier, a carbon monoxide transformer and a hydrogen purifier collectively. CONSTITUTION:A device for producing hydrogen by steam modifying reaction from a hydrocarbon and/or an alcohol, the production device is equipped with an upright cylindrical burner 1, a cylindrical radiating plate 2 which covers the burner and has the open top, plural upright closed reaction tubes 3 which are arranged annularly at the outer periphery of the radiating plate at a specific interval from the radiating plate and have the lower end led to the an off-gas outlet 3a and a closed case 4 which covers the burner and the reaction tubes and has an exhaust vent 1a of an exhaust gas of combustion at the bottom. The reaction tubes have an upright feed pipe 10 of a raw material which has the top opening to the inside of the reaction tubes and the lower end led to a feed opening 10a of a raw material, an upright hydrogen taking out pipe 11 which covers the outer peripheral side of the feed pipe of the raw material, has the open top and the lower end led to a hydrogen outlet 11a and an upright closed hydrogen permeating pipe 12 which covers the outer periphery of the hydrogen taking out pipe, has the closed top and the lower end led to the a feed opening 12a of a sweeping gas. A reforming catalyst 5 is packed between the hydrogen permeating pipe and the reaction tubes.

    • PROBLEM TO BE SOLVED: To provide a hydrogen-producing device whose hydrogen partition walls have improved durability and which can produce highly pure hydrogen, by using a molded plate-like reforming catalyst. SOLUTION: The molded plate-like reforming catalyst 126 is preferably formed by carrying a Ni-based catalyst or the like on a metal such as stainless steel. A hydrogen-penetrating rectangular member 34 is provided with an inside wall 28 near to the plate-like reforming catalyst 126 and with an outside wall 32 near to the adjacent unit. The inside wall 28 and the outside wall 32 are formed from hydrogen- penetrating metal membranes, respectively. The unit is provided with a spacer 127 which is fixed to the plate-like reforming catalyst 126 and a hydrogen-penetrating rectangular member 34 by a welding method or the like, and is extended in the longitudinal direction of the hydrogen-penetrating rectangular member 34. Thereby, the spacer 127 is disposed between the hydrogen-penetrating rectangular member 34 and the plate-like reforming catalyst 126 of each unit, and when the unit is assembled in the second space, the spacer 127 of the outside wall 32 is also disposed between the outside wall 32 and the adjacent plate-like reforming catalyst 126. Thus, the damage of the metal membrane due to the contact with the plate-like reforming catalyst 126 is not caused.
