BURNER ASSEMBLY WITH TIGHT SHUT-OFF OPPOSED LOUVER AIR DAMPER |
摘要 |
<p>An opposed louver air damper apparatus for controlling the flow rate of combustion air to a burner fire box, comprising a plurality of adjacent, rotatable louvers having rubber tips and side gaskets providing sealing between the louvers and a frame, and geared responsive shafts supporting the louvers for controllably rotating the louvers to determinative positions to modulate the volume of air passing through the louver apparatus, wherein the gears in meshing engagement precisely maintains the relative position of the louvers, and the gaskets operate to minimize undesirable leakage through the air damper. The gears form teeth in arcuate portions of the full circumference to limit the rotational movement to only that within the toothed portion of the gear.</p> |
