Abstract
A reformer of the present disclosure includes a reformer body having a cylindrical shape that carries out a reforming reaction by a raw fuel gas and water supplied thereto, the reformer body including therein a vaporization portion which generates steam and a reforming portion which reacts the steam generated in the vaporization portion with the raw fuel gas to generate a reformed gas, at least one of a convex portion and a rough portion having a higher degree of surface roughness than that of other portions, being disposed on at least one of an inner circumferential surface and an outer circumferential surface of the reformer body.
Claims19
A reformer, comprising:
- a reformer body having a cylindrical shape that is configured to carry out a reforming reaction by a raw fuel gas and water configured to be supplied thereto,
- the reformer body comprising:
- an inner circumferential surface,
- an outer circumferential surface,
- a vaporization portion configured to generate steam,
- a reforming portion configured to react the steam generated in the vaporization portion with the raw fuel gas to generate a reformed gas, and
- a convex portion disposed on the inner circumferential surface or the outer circumferential surface and/or a rough portion disposed on the inner circumferential surface or the outer circumferential surface;
- wherein the rough portion has a higher degree of surface roughness than that of other portions of the reformer body, and
- when viewed from a direction of a central axis line of the reformer body, any convex portion and/or rough portion of the reformer body are disposed only on an upper side of the central axis line of the reformer body.
