Gas burner system and method thereof

A method of operation for a fired vessel, the method comprising:

• providing a tank containing a volume of liquid and a tube submerged in the volume of liquid within the tank;
• and including a metal box defining an interior volume, wherein the metal box is within the tube and adjacent one end of the tube;
• and including a main burner assembly that extends through the metal box and a first venturi surface within the main burner assembly;
• and including a pilot burner assembly that extends through the metal box adjacent the main burner assembly and a second venturi surface within the pilot burner assembly;
• selecting a first fitting for connection with the main burner assembly, wherein the first fitting has a first diameter, and after selecting the first fitting, then coupling the first fitting to the main burner assembly;
• selecting a second fitting for connection with the pilot burner assembly, wherein the second fitting has a second diameter, and after selecting the second fitting, then coupling the second fitting to the pilot burner assembly;
• coupling a fuel source to the main burner via the first fitting and coupling the fuel source to the pilot burner via the second fitting;
• supplying fuel from the fuel source to the main burner assembly through the first fitting and supplying fuel from the fuel source to the pilot burner assembly through the second burner, wherein fuel pressure in the main burner assembly supplied from the fuel source depends on the selection of the first fitting having the first diameter and fuel pressure in the pilot burner assembly supplied from the fuel source depends on the selection of the second fitting having the second diameter;
• and
• moving air through a first flame arrestor connected to the tube, wherein the first flame arrestor defines an air-intake opening;
• moving a moveable plate between a closed first position and an open second position via a plunger, wherein the moveable plate is operatively coupled to the air-intake opening wherein the first flame arrestor provides ambient air to the main burner assembly and the pilot burner assembly via the air-intake opening when the moveable plate is in the open second position;
• and
• moving air through a second flame arrestor coupled to the metal box, wherein the second flame arrestor creates create an air-fuel mixture inside the first and second venturi surfaces.
