1. A burner comprising:
- a first conduit comprising a first end, a second end, a longitudinal bore having a longitudinal axis, and an external surface;
a second conduit substantially concentric with the first conduit, the second conduit comprising a first end, a second end, and an internal surface;
the first and second conduits configured to form a primary annulus between the external surface of the first conduit and the internal surface of the second conduit;
an adjustable structure comprising a body having an upper surface, a lower surface, a circumferential surface abutting a portion of the internal surface of the second conduit, and a generally cylindrical central hub concentric with the longitudinal axis and extending axially away from the lower surface of the body, the structure adjustable axially in relation to and removably attached to the first end of the first conduit via the generally cylindrical central hub, the generally cylindrical central hub defining a substantially central passage having an exit at the upper surface, the substantially central passage comprising an angled section and a vertical connector section connecting the angled section with a threaded section of the generally cylindrical central hub, the angled section forming an angle γ
to the longitudinal axis ranging from about 10 degrees to about 45 degrees, the body comprising one or more non-central through passages extending from the lower to the upper surface, the one or more non-central passages configured such that flow of a first fluid through the one or more non-central passages causes the first fluid to intersect a flow of a second fluid in a mixing region above the upper surface of the body.

Abstract
Apparatus includes a first and second conduits configured to form an annulus between them. An adjustable structure includes a body having an upper surface, a lower surface, and a circumferential surface abutting a portion of the internal surface of the second conduit. The structure is adjustable axially in relation to and removably attached to the first conduit via a hub. The hub defines a central passage for fuel or oxidant. The body has one or more non-central through passages configured such that flow of an oxidant or fuel therethrough causes the fuel or oxidant to intersect flow of fuel or oxidant exiting from the central passage in a region above the upper surface of the body.

8. An adjustable burner apparatus comprising:
-
a first conduit comprising a first end, a second end, a longitudinal bore having a longitudinal axis, and an external surface, the first end comprising threads on the external surface, a second conduit substantially concentric with the first conduit, the second conduit comprising a first end, a second end, and an internal surface, the first and second conduits configured to form a primary annulus between the external surface of the first conduit and the internal surface of the second conduit; a body having an upper surface, a lower surface, a circumferential surface abutting a portion of the internal surface of the second conduit, the body including a circumferential lip extension extending away from the upper surface of the body and generally parallel to the longitudinal axis, and a generally cylindrical central hub concentric with the longitudinal axis and extending axially away from the lower surface of the body, the body adjustable axially in relation to and threadedly attached to the threads of the first end of the first conduit via a threaded section of the generally cylindrical central hub, the generally cylindrical central hub defining a substantially central passage having an exit at the upper surface, the substantially central passage comprising an angled section and a vertical connector section connecting the angled section with the threaded section of the hub, the angled section forming an angle γ
to the longitudinal axis ranging from about 10 degrees to about 45 degrees, the body comprising one or more non-central through passages extending from the lower to the upper surface, the one or more non-central passages configured such that flow of a first fluid through the one or more non-central passages causes the first fluid to intersect a flow of a second fluid in a mixing region above the upper surface of the body;a third substantially concentric conduit comprising a first end, a second end, and an internal surface, the internal surface of the third conduit forming, with an exterior surface of the second conduit, a secondary annulus external to the primary annulus; the first end of the third conduit extending beyond the first end of the second conduit, the first end of the second conduit extending beyond the first end of the first conduit, and the secondary annulus is capped by an end cap connecting the first end of the second conduit and the first end of the third conduit; and the second end of the second conduit sealed around the first conduit, and the second end of the third conduit sealed around the second conduit, forming a cavity for fluid to circulate. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
