Abstract
A noiseless premix burner comprising a cylindrical housing which is attached to the outer covering of the furnace wall, and closed at its opposite end by a closure plate which supports a concentric burner tube which extends from the closure plate through an opening in the furnace wall to the interior of the furnace. A gas fuel line is inserted along the axis of the burner tube. Pressurized fuel gas flows through an orifice in the fuel line in an expanding flow. The proximal end of the burner tube has a venturi type throat construction. The annular space between the burner tube and the cylindrical housing comprises two plenums, one adjacent the outer wall of the furnace supplying secondary air, which passes into the furnace through a narrow annular gap between the burner tube and the furnace lining. The second plenum provides primary air to the burner tube at the position of the fuel nozzle, where it mixes turbulently with the inflowing high velocity gas stream, to provide a fuel-air mixture which passes down the burner tube. The axial outlet of the burner tube inside the furnace is closed and there are a plurality of longitudinal slots spaced circumferentially around the burner tube through which the gas-air mixture moves radially into the furnace impinging on tile which surrounds the burner tube.
