Abstract
A burner assemblage includes an elongated, round burner assembly having a central axis and including internal baffle structure. The baffle structure is arranged to cause concentric primary and secondary air flows to move in a direction generally parallel to said axis. The secondary air flow is generally annular in shape and the same is disposed in generally surrounding relationship relative to said primary air flow. The assemblage also includes a swirler structure for swirling the air primary and secondary air flowing through the central portions of the burner. The swirler structure includes a first swirler component located in a position for swirling the primary air flow. The first swirler component has an outer circumferential edge that extends around the axis of the burner in radially spaced relationship thereto. The swirler also includes a second generally annular swirler component located in a position for swirling the secondary air flow independently of the swirling of the primary air flow. The second swirler component has an internal annular edge that extends around the axis in spaced relationship thereto. The internal annular edge of the second swirler component is greater in diameter than the outer circumferential edge of the first swirler component so that the two swirler components may be arranged concentrically in essentially the same plane. Ideally the swirler components are arranged to swirl the respective primary and secondary air flows in the same general direction and with essentially the same intensity.
