Rotary cup burner for ship's boiler
KB-W™ - 0.55 - 6.2 MW Aalborg Industries

The KB-W™ rotary cup burner has been designed to meet customer requirements and offers reliable operation, easy maintenance and minimum installation requirements. The design is based on Aalborg Industries' long-term experience in marine boilers and combustion technology, ensuring optimum burner performance for demanding customers.

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 required for complete
combustion is supplied by a forced draught fan through the windbox and burner air register. Normally, atomizing is effected at a viscosity of approx. 45 cSt, which ensures a particle size small enough to burn quickly and completely.

Diesel oil, heavy fuel oil or waste oil fired rotary cup burner KB-W™ is a typical waste oil-fired rotary cup burner with an air-cooled pre-combustion chamber with brickwork.
