Steam methane reformer and hydrogen station having it using high performing metal fiber burner

1. 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 ).

2. The steam methane reformer according to claim 1 , wherein the premixed metal fiber burner ( 120 a ) further includes a mixing part ( 123 ) in which the fuel and the air or the hydrogen are mixed before being introduced into the premixing chamber ( 122 ).

3. The steam methane reformer according to claim 1 , wherein the flashback preventing means ( 128 ) is provided in plural in a length direction of the premixing chamber ( 122 ), and a surface area of specially designed slits and holes ( 129 ) is gradually reduced, as the back flame preventing means ( 128 ) is disposed to be adjacent to the metal fiber mat ( 124 ).

4. The steam methane reformer according to claim 1 , wherein the hydrogen supplying part ( 126 ) supplies hydrogen containing a large amount of inert gas.

5. The steam methane reformer according to claim 1 , wherein the premixed metal fiber burner ( 120 a ) has a plurality of temperature measuring means ( 160 ).

6. A hydrogen station, comprising:

a steam methane reformer ( 100 ) according to any one of claims 1 to 5 ;

separating/refining means ( 200 ) for increasing hydrogen purity contained in gas collected by the hydrogen discharging part ( 140 ) of the steam methane reformer ( 100 );

hydrogen injecting means ( 300 ) for charging hydrogen having a high purity to a target object; and

a storing part ( 400 ) for storing the produced hydrogen.
