Twin air Burners

GF-ELTI twin air burners are part of the macro-family of cold-air burners.

These burners have a double air supply: internal combustion air for flame generation and “secondary” air conveyed outside the flame nozzle. The two air flows are managed separately.

Secondary air enables to improve re-heat uniformity at low temperatures (≤ 600 °C).

This type of burners is equipped with an in-built ignition electrode or with a pilot burner, according to size.

Accurate flame temperature regulation and controlled furnace cooling without using dedicated nozzles or circuits are the main advantages of this solution.

Operating temperatures of burners: ≤ 1,150 °C.

“Secondary air” operating temperatures: ≤ 600 °C.

Applications: Heat Treatment Furnaces.
