Patent ID: 8388707

Claim:
A steam methane reformer using a high performing metal fiber burner, comprising: a reforming part ( 110 ) which is provided with a plurality of reaction tubes ( 110 a ) in which a catalyst for steam-reforming hydrocarbon materials and producing hydrogen is disposed; a combustion part ( 120 ) which is provided with a premixed metal fiber burner ( 120 a ) for generating heat required for the steam reforming reaction of the reaction tubes ( 110 a ); a raw material supplying part ( 130 ) for supplying hydrocarbon materials to the plurality of reaction tubes ( 110 a ); and a hydrogen discharging part ( 140 ) for discharging hydrogen produced through the steam reforming reaction by the catalyst of said plurality of reaction tubes ( 110 a ); and wherein the premixed metal fiber burner ( 120 a ) comprises: a main body ( 121 ) formed with a cylindrical premixing chamber ( 122 ) in which air, fuel, and hydrogen are mixed; a metal fiber mat ( 124 ) which is formed at one side of the main body ( 121 ) to form a flame; a fuel/air supplying part ( 125 ) which is formed at the other side of the main body ( 121 ) to supply the air or fuel; a hydrogen supplying part ( 126 ) which is formed at another side of the main body ( 121 ) to supply the hydrogen; and an ignition part ( 127 ) for igniting the metal fiber mat 124 , and wherein the premixing chamber ( 122 ) includes flashback preventing means ( 128 ) which is formed with a plurality of specially designed slits and holes ( 129 ) and arranged orthogonally to a flowing direction of the fuel, the air or the hydrogen so as to increase a flowing speed of the fuel, the air or the hydrogen and also transfer heat of the flame to a peripheral portion thereof, thereby preventing the flame in the metal fiber mat ( 124 ) from being flow back to the premixing chamber ( 122 ), and wherein the premixed metal fiber burner ( 120 a ) is disposed at one side of the steam methane reformer ( 100 ), and the combustion part ( 120 ) is formed in a direction of flame generated by the premixed metal fiber burner ( 120 a ), and the reforming part ( 110 ) is formed to enclose the combustion part ( 120 ).
