Abstract
A baffle assembly and burner including the baffle assembly. The baffle assembly includes a collar having a central axis. A plurality of vanes are secured to the collar. Each vane includes a leg extending from the collar at a first angle with respect to the central axis. The first angle of the leg is configured to impart rotation to a flow of fluid through the baffle assembly. An impingement plate extends from the leg at a second angle with respect to the central axis. The second angle is greater than the first angle.
Claims20
A baffle assembly, comprising:
- a collar having a central axis;
- and,
- a plurality of vanes secured to the collar, each vane comprising:
- a leg extending from the collar at a first angle with respect to the central axis, the first angle of the leg configured to impart rotation to a flow of fluid through the baffle assembly, wherein the flow of fluid is directed from the collar to the plurality of vanes between differing flow cavities;
- and
- an impingement plate extending from the leg at a second angle with respect to the central axis, wherein the second angle is greater than the first angle, and wherein the impingement plate is configured to reduce a velocity of the flow of fluid and an entrance length proximate to a transition between the differing flow cavities.

A burner assembly, comprising:
- a first inlet;
- dissimilar flow cavities on opposite sides of the first inlet;
- and
- a baffle assembly installed in, at, or proximate to the first inlet, the baffle assembly comprising:
- a collar having a central axis;
- and
- a plurality of vanes secured to the collar, each vane of the plurality of vanes comprising:
- a leg extending from the collar at a first angle with respect to the central axis, the first angle of the leg configured to impart rotation to a flow of fluid through the baffle assembly;
- and
- an impingement plate extending from the leg at a second angle with respect to the central axis, wherein the second angle is greater than the first angle.
