The KBE™ burner also has a 5-15% lower power consumption than the KB™ (relative to burner size). The low weight KBE™ burner can be bolted or welded onto the boiler and is designed to sustain shipment well due to its sleek design. The working principle of rotary cup burners is based on atomizing by centrifugal force. The atomizing cup is driven at high speed via a heavy-duty belt drive.
The oil is gently positioned at low pressure into the spinning cup where gradually, and forced by the centrifugal action of the cup, it moves forward until it is thrown off the cup rim as a very fine, uniform film. The high-velocity primary air discharged around the cup strikes the oil film, breaks it up and converts it into a mist of fine particles, which are introduced into the combustion zone and burner.
The secondary air necessary for complete combustion is supplied by a forced-draught fan through the windbox and burner air register. A safety device built into the KBE™ prevents wrong adjustment of tertiary air that may cause damage to the swirler and cup.
