Example Embodiment

[0029] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0030] As shown in FIG. 1 , the intensive reformer is used in a fuel cell system of a solid oxide fuel cell, which generates electric power through a reduction reaction of a reformed gas. Therefore, the intensive reformer has the function of supplying the reformed gas to the cell stack in the solid oxide fuel cell system.

[0031] The reformer includes: a start-up combustion chamber 100, which provides heat energy for endothermic steam reforming to the reformer 200 through ignition and combustion of natural gas and air; the reformer 200 uses the generated heat energy to pass a reforming reaction The catalyst of unit 14 reformates the natural gas with steam to produce a hydrogen-containing reformate gas.

[0032] Therefore, in order to save energy consumption, the start-up combustion chamber 100 is connected to the reformer 200 through a shor...

Abstract

The invention provides a catalytic reforming unit used for a solid oxide fuel cell. The catalytic reforming unit is characterized in that a starting combustion chamber is connected with a reformer through a pipeline or the starting combustion chamber is assembled and connected with the reformer together firmly and tightly; a reforming reactor consists of a reforming reacting unit, an upper sealing set and a lower sealing set of an air flue; the reformer is formed by stacking one or a plurality of reforming reactors with same structure; the adjacent reforming reactors are separated by using an air flue separating plate and then are fixedly tightened by using an upper covering plate and a lower covering plate through nuts, thus allowing cold and hot fluids to flow at an upper side and a lower side of the reacting unit and not to be mixed up. The fluid flows from down to up or from up to down among the reforming reactors. The catalytic reforming unit has the advantages of high energy utilization, small and compact structure and easy detachment and use.

Description

technical field [0001] The invention relates to a catalytic reforming device, especially an intensive catalytic reforming device for a solid oxide fuel cell system. Background technique [0002] At present, it is urgent to build an energy-saving and environment-friendly society. Hydrogen energy will be the energy source of human beings in the future, and fuel cells are the best way to utilize hydrogen energy. The industrial steam reforming hydrogen production technology is quite mature. The large-scale reforming system consists of many tubular reactors filled with spherical catalysts. The operating temperature is above 850°C and the pressure exceeds 25bar. The reactor is 12m long. It needs to be made of expensive alloy steel to withstand the high temperature and reducing gas environment. This large-scale hydrogen production technology cannot meet the compact and miniaturized requirements of the fuel cell system. It is not feasible to simply reduce the design parameters of t...
