Abstract
The present invention provides an improved nozzle mixing line burner for automatically increasing available oxygen for combustion as the fuel gas flow rate increases. This improved nozzle mixing line burner includes a pair of fuel gas manifolds, each of which has a row of gas discharge ports discharging laterally and toward the opposite manifold to provide streams of fuel gas. An orifice plate extends between the fuel gas manifolds and includes a plurality of rows of air orifices extending along the line of the burner, with the air orifices closest to the gas manifolds being relatively smaller in size and the more internally disposed rows of air orifices increasing in orifice size toward the middle of the orifice plate, to increase the available air supply proportionately as the velocity of the fuel gas flow increases.
