  • Baffle assembly for modifying transitional flow effects between different cavities
    Patent number: 11530711
    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.
    Type: Grant
