The ALM Series burners receive the air for combustion via the air suction chamber. After passing
through this air suction chamber, the combustion air enters into the burner and reaches the
combustion head mixing point via a fan operating in the volute shaped casing. The mixing point
consists of the air diffuser and the combustion head. Here, the fuel injected by the nozzle mixes with
air to form an ideal burning mixture. This way, smooth combustion and maximum fuel savings are
obtained.
