Air acetylene

From GAWDAwiki

Air acetylene is a low-temperature flare produced by burning acetylene with air instead of oxygen. ^[1]

The air acetylene process operates on the Bunsen burner principle, i.e., the acetylene flowing under pressure through a Bunsen jet aspirates the appropriate amount of air for combustion purposes.

Acetylene is obtained from a cylinder through a pressure regulator and hose. As the acetylene flows through the torch it draws air from the atmosphere into it in order to obtain the oxygen necessary for combustion.^[2]
