  • Steam methane reformer and hydrogen station having it using high performing metal fiber burner
    Patent number: 8388707
    Abstract: The steam methane reformer using a premixed metal fiber burner which has a short flame length as well as a high temperature to thereby provide a high efficiency and also reduce a size, and a hydrogen station having the same. The steam methane reformer using a high performing metal fiber burner comprises a reforming part (110a) 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 (120a) for generating heat required for the steam reforming reaction of the reaction tubes (110a); a raw material supplying part (130) for supplying hydrocarbon materials to the reaction tube (110a); and a hydrogen discharging part (140) for discharging hydrogen produced through the steam reforming reaction by the catalyst of the reaction tube (110a).
