A method of combustion and a reformer. The method includes combusting a fuel in a combustion region of an up-fired or down-fired reformer and forming non-uniform injection properties with a wall-bound burner. The combusting is performed in a combustion region by burners, wherein at least one of the burners is the wall-bound burner forming the non-uniform injection properties. The non-uniform injection properties generate a heat profile providing a first heat density proximal to a wall and a second heat density distal from the wall, the second heat density being greater than the first heat density. The non-uniform injection properties are formed by injection properties selected from an angle of one or more injectors, a flow rate of one or more injectors, an amount and/or location of oxidant injectors, an amount and/or location of fuel injectors, and combinations thereof.

The method of claim 1, wherein the plurality of injectors of the wall-bound burner comprises a first set of injectors and a second set of injectors, wherein the non-uniform injection properties are formed by the flow through one or more injectors of the first set of injectors and the second set of injectors of the wall-bound burner, the flow through the one or more injectors comprising a first fluid flow from the first set of injectors of the wall-bound burner and a second fluid flow from the second set of injectors of the wall-bound burner, the first set of injectors being proximal to the one or more walls and the second set of injectors being distal from the one or more walls. 3. The method of claim 2, wherein the first fluid flow differs from the second fluid flow by composition. 4. The method of claim 3, wherein the first fluid flow comprises a fuel. 5. The method of claim 4, wherein the first fluid flow has a first fuel-to-oxidant ratio and the second fluid flow has a second fuel-to-oxidant ratio, the first fuel-to-oxidant ratio being less than the second fuel-to-oxidant ratio. 6. The method of claim 3, wherein the first fluid flow comprises an oxidant. 7. The method of claim 6, wherein the first fluid flow includes a lower fuel-to-oxidant ratio than the second fluid flow. 8. The method of claim 2, wherein the first fluid flow has a first flow rate and the second fluid flow has a second flow rate, the first flow rate being different from the second flow rate. 9. The method of claim 8, wherein the first flow rate is zero. 10. The method of claim 1, wherein the plurality of injectors of the wall-bound burner comprises a first set of injectors and a second set of injectors, wherein the non-uniform injection properties are formed by the angle of one or more injectors, of the first set of injectors and the second set of injectors of the wall-bound burner, the angle of the one or more injectors comprising a first injector angle for the first set of injectors and a second injector angle for the second set of injectors, the first injector angle being different from the second injector angle. 11. The method of claim 1, wherein the plurality of burners are arranged in a plurality of rows. 12. The method of claim 1, wherein the plurality of injectors of the wall-bound burner comprises oxidant injectors and the plurality of injectors of the non-wall-bound burner comprises oxidant injectors, and wherein the amount of oxidant injectors in the wall-bound burner differs from a second amount of oxidant injectors in the non-wall-bound burner. 13. The method of claim 1, wherein the plurality of injectors of the wall-bound burner comprises fuel injectors and the plurality of injectors of the non-wall-bound burner comprises fuel injectors, and wherein the amount of fuel injectors in the wall-bound burner differs from a second amount of fuel injectors in the non-wall-bound burner.
