Abstract
A reformer having high durability and including a heating unit and a reforming unit. The heating unit has a hollow cylindrical shape or polygonal shape and a first combustor and a second combustor that receives and oxidizes heating unit fuel and anode off gas (AOG) at both ends thereof. The reforming unit includes a first reforming portion formed to surround the exterior of the heating unit, a second reforming portion formed to surround the exterior of the first reforming portion and a flow path portion connecting the first reforming portion and the second reforming portion to provide fluid communication therebetween. The flow path portion includes a pre-deformed portion extending along a direction substantially perpendicular to the central axis of the heating unit.
Claims13
A reformer comprising:
- a heating unit;
- a first combustor configured to receive and oxidize a heating unit fuel at a first end of the heating unit;
- a second combustor configured to receive and oxidize an anode off gas (AOG) at a second end of the heating unit;
- and
- a reforming unit comprising a first reforming portion surrounding the heating unit, a second reforming portion surrounding the first reforming portion, and a flow path portion connecting the first reforming portion and the second reforming portion to provide fluid communication therebetween,
- wherein the flow path portion comprises a pre-deformed portion comprising a curved portion comprising a top-curved plate of the flow path portion and a bottom-curved plate of the flow path portion, the pre-deformed portion extending along a direction substantially perpendicular to the central axis of the heating unit and being configured to increase the structural integrity of the reforming unit at the flow path portion.
A reformer comprising:
- a heating unit extending along a first axis;
- a first combustor configured to receive and oxidize a heating unit fuel at a first end of the heating unit;
- a second combustor configured to receive and oxidize an anode off gas (AOG) at a second end of the heating unit;
- and
- a reforming unit comprising a first reforming portion surrounding the heating unit, a second reforming portion surrounding the first reforming portion, and a flow path portion connecting the first reforming portion and the second reforming portion to provide fluid communication therebetween, wherein the flow path portion comprises a pre-deformed portion comprising a curved portion having a convex surface, the pre-deformed portion extending along a second axis crossing the first axis of the heating unit, the pre-deformed portion being configured to increase the structural integrity of the reforming unit at the flow path portion.
A reformer comprising:
- a heating unit;
- a first combustor configured to receive and oxidize a heating unit fuel at a first end of the heating unit;
- a second combustor configured to receive and oxidize an anode off gas (AOG) at a second end of the heating unit;
- and
- a reforming unit comprising a first reforming portion surrounding the heating unit, a second reforming portion surrounding the first reforming portion, and a flow path portion connecting the first reforming portion and the second reforming portion to provide fluid communication therebetween,
- wherein the flow path portion comprises a pre-deformed curved portion comprising a top-curved plate of the flow path portion and a bottom-curved plate of the flow path portion extending along a direction substantially perpendicular to the central axis of the heating unit,
- wherein the pre-deformed curved portion has contour lines defining three concentric circles around the central axis of the heating unit comprising an innermost circle, an outermost circle, and a middle circle between the innermost circle and the outermost circle,
- wherein the innermost circle is separated from the middle circle by a distance d1, and is separated from the outermost circle by a distance d2,
- wherein d2 is greater than or equal to twice the value of the distance d1.
