Apparatus and method for a burner nozzle assembly

A burner nozzle assembly, said burner nozzle assembly having a longitudinal axis and comprising:

• (a) a nozzle body, said nozzle body having a body inlet end, a body outlet end spaced apart from the body inlet end, a body air inlet adapted to convey a quantity of air, and a body fuel inlet adapted to convey a quantity of fuel;
• (b) a nozzle mixer, said nozzle mixer having a mixer inlet end, a mixer outlet end spaced apart from the mixer inlet end, a tapered mixer air inlet adapted to convey the quantity of air, a mixer fuel inlet adapted to convey the quantity of fuel, and a mixing zone, and said mixer inlet end being disposed adjacent to the body outlet end;
• (c) a nozzle cap, said nozzle cap being disposed adjacent to the body outlet end and the nozzle mixer;
• (d) a pintle, said pintle being partially and removably disposed in the nozzle mixer;
• wherein the body air inlet is in fluid communication with the tapered mixer air inlet;
• and
• wherein the body fuel inlet is in fluid communication with the mixer fuel inlet;
• and
• wherein the body air inlet and the body fuel inlet keep the quantity of air and the quantity of fuel separate from each other;
• and wherein the tapered mixer air inlet forms a substantially conical shape and is disposed at an angle relative to the longitudinal axis;
• and wherein the tapered mixer air inlet is in fluid communication with the mixer fuel inlet which is disposed substantially parallel to the longitudinal axis.
