Description
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.
