KB™
Rotary cup burner for heavy fuel oil or diesel oil
KB™ 1600 – KB™ 3400
____________________________________________________________________________________________
General
The operation of the KB™ rotary
cup burner is automatic, simple
and reliable – also when fired
with a combination of fuels as
is often the case. The design is
compact and the burners easy
to maintain.

Description
The KB™ rotary cup burner has been
designed to meet customer requirements
such as 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 atomising by centrifugal
force. The atomising 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. Normally,
atomizing is effected at a viscosity of
approx. 45 cSt. which ensures a particle
size small enough to burn quickly and
completely.
Heavy fuel oil fired rotary cup burner
The KB™ burner is a typical rotary cup
burner with combustion air according
to the forced draught fan location principle.
Larger burners of types
KB™ 1600–3400 have a separate primary
air fan that receives its air supply from
the forced draught fan.
