Abstract
In one embodiment, a burner for use in synthesis gas production includes multiple burner units each configured to deliver fuel and oxygen to a combustion chamber, each burner unit including an inner outlet pipe configured to deliver fuel and an outer outlet pipe configured to deliver oxygen, the outer outlet pipe concentrically surrounding the inner outlet pipe.
Claims15
A burner comprising a plurality of burner units,
- wherein each burner unit comprises an inner pipe and an outer pipe concentrically surrounding the inner pipe,
- wherein each burner unit further comprises a flow restrictor configured to restrict flow of a first fluid within the inner pipe and to restrict flow of a second fluid within the outer pipe,
- wherein the flow restrictor comprises a central disk and a cylindrical member extending from one side of the central disk, wherein an end of the inner pipe is received within the cylindrical member,
- wherein the central disk of the flow restrictor includes a central portion and a peripheral portion, wherein the central portion is configured to restrict flow of the first fluid within the inner pipe that is received within the cylindrical member of the flow restrictor, and wherein the peripheral portion is configured to restrict flow of the second fluid within the outer pipe surrounding the inner pipe, and
- wherein the central portion of the central disk has a plurality of inner openings extending through the central disk and the peripheral portion of the central disk has a plurality of outer openings extending through the central disk.
2 more elements
A burner, comprising:
- a first plenum chamber and a second plenum chamber;
- a plurality of inner supply pipes each in fluid communication with and extending from the first plenum chamber;
- a plurality of outer pipes each in fluid communication with and extending from the second plenum chamber;
- a plurality of flow restrictors, wherein each respective flow restrictor is mounted to an end of one of the inner supply pipes, wherein each flow restrictor comprises a central disk that includes a central portion and a peripheral portion, wherein the central portion of the central disk has a plurality of inner openings extending through the central disk and the peripheral portion of the central disk has a plurality of outer openings extending through the central disk;
- and
- a plurality of inner outlet pipes, wherein an end of each respective inner outlet pipe is connected to one of the flow restrictors,
- wherein each respective outer pipe concentrically surrounds one inner supply pipe and one inner outlet pipe,
- wherein the central portion of each flow restrictor is configured to restrict flow of a first fluid from the first plenum chamber, through the inner supply pipe to which the respective flow restrictor is mounted, and into the inner outlet pipe that is connected to the respective flow restrictor, and wherein the peripheral portion is configured to restrict flow of a second fluid from the second plenum chamber through the outer pipe surrounding the inner supply pipe to which the respective flow restrictor is mounted and the inner outlet pipe that is connected to the respective flow restrictor.
