Bulletin 1/2011 - Siempelkamp

the turn-down ratio of the burner systems
is dependent on the system capacity and
the fuel type. For gaseous fuels the ration
is 1:10, liquid fuels 1:7 and solid fuels 1:5.
the burner basically consists of the burner
housing with a graduated combustion air
system, the cooled and refractoried burner
muffle including dust nozzle, gas and/or
oil lance. With such a design even cool
combustion chambers with or without gas
or oil support flame can be fired with dust
right from the beginning.
Büttner’s combination burner type BCB
can be operated with 300 °C pre-heated
air. the graduated combustion air reduces
nOx-emissions. together with swirl and
core air, the flame geometry can be adjusted.
the robust design, the exchangeable
wear protection at the dust intake and
sufficient, easy to access maintenance and
control hatches greatly ease the operation
and maintenance of the burner.
Control know-how meets first-class
service
Operation of the system, including the adjustment
of the optimal fuel/combustion
air ratio is done fully automatic and
dependent on the firing demand. the

auxiliary equipment with all components
for fuel supply, controls and dosing, is
designed according to the latest safety
requirements. this relates particularly to
flame monitoring performed by component
tested UV and/or IR flame sensors.
the ignition utilizes a gas-electric operated
gas ignition burner.
