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.
