AGF Burner, Inc.

Oxygen – Gas Burner Equipment

Oxygen – Gas burner equipment is used where the temperature, heat intensity, or flame concentration is obtainable with air-gas burner equipment is insufficient to produce satisfactory results.  Electronic tube manufacturing, glass working, silver soldering, copper brazing, localized hardening and annealing are but a few of the many applications for which AGF Burner, Inc.’s Oxygen – Gas burner equipment is used.

Principle of operation:

            AGF’s oxy-gas burner equipment is designed for use with oxygen at a pressure of approximately 5 pounds per square inch and natural gas or bottled gas(propane) at pressures ranging from 3”-8”(inches) water column.  On larger applications such as complicated glass working machines it is customary to use a gas booster to obtain gas pressure up to approximately 1 pound per square inch.  This will help eliminate the possibility of marginal difficulties.  Higher oxygen pressures can be used to obtain greater heat intensities if they are required.

                A properly sixed AGF Burner, Inc.’s Oxygen-Gas or combination three way Oxygen-Gas-Air Venturi mixer must be used to obtain maximum burner efficiency under all operating conditions.  The use of an improper mixer can cause any one or all of the following conditions. 

1)      Inability to secure a proper mixture

2)      Flashbacks

3)      Oxygen in gas line

4)      Mixture variations due to fluctuations in supply line pressures.  This especially true when operating with natural gas.

For fine adjustment of burner settings, we recommend the use of needle valves.  

Oxygen-Gas Operating and installation precautions:

                The following precautions must be observed to obtain trouble – free operation of oxygen – gas burner equipment.

1)      Use the correctly sized AGF Burner, Inc.’s Venturi mixer for each burner set-up

2)      Install a fire check of suitable capacity between the Venturi mixer and the burners.  The fire check does not prevent a flashback, but retards combustion back into the mixture line in the event of a flashback.  These fire checks must be used in oxygen-gas burner installations.

3)      Do not install any valves, cocks, or restrictions other than a fire check between the Venturi mixer and the burners. 

4)      The Venturi Mixer should be placed as close as possible to the burners or burner manifold to avoid storing up too large a quantity of an explosive mixture. 

5)      All piping should be of sufficient size.  A common error that is made in burner installations is the use of under sized piping.  Whenever possible the mixture supply line to the burners should be of equal size or larger than the pipe size of the outlet of the Venturi mixer.

6)      Wherever possible, all fittings and piping directly connected to the oxygen-gas burners should be of copper or brass material to conduct heat away from the burners, thereby preventing over-heating.

7)      Make certain that there is no oil or grease in the fittings, piping, etc. of the oxygen-gas burner set-up.

8)      To minimize the possibility of flashing-back the following rule should be observed:

1. Turn on gas, light;
2. Turn on oxygen.
3. Turning off – turn off oxygen first, then gas last.

9)      The gas and oxygen should be shut off immediately in the event of a flashback.
