Combined burner and fan - has ignition device supported on radial arms which impart swirling motion to air-fuel mixture

摘要

The combined fan and burner has a combustion air duct (2) with a zone (3) of reduced dia. in which axially adjustable fuel nozzles (5) are mounted in a nozzle head (1). The nozzle head (1) is mounted on the downstream side of a baffle plate (7) which has openings fitted with guide vanes (6) which impart a swirling motion to the combustion air. The burner combustion chamber (9) is enclosed in the flame tube (10) which is mounted coaxially with the air duct (2). The ignition device (11) is mounted in the flame tube (10) and has three radial arms (13). These arms are set at an angle to the flame tube azis so that an additional swirling motion is imparted to the mixture of air and fuel flowing into the flame tube (10). Ul - Omin urnr nd fn.
