Adjustment
of
the
combustion head
The oil burner
is
delivered with a combustion head and an air diffuser disc that suit the
specified boileTtype and oil quantity in the best way.Figure I illustrates the combustion
head for KBO-R13/l4M burners,Figure 2 for a KBO-RI5M burner, and finally Fig-
ure 3 for
KBO-R20/60M
burners.
To obtain the best possible combustion performance the combustion head should be
adjusted to fit the actual boiler furnace. The combustion quality can be checked by
means
of
flue gas analysis.The air velocity in the combustion head can be adjusted by
loosening the fixing screwin the adjustment ring and moving the ring (4) in the direction
of
the flame tube (6) to change the distance between the adjustment ring and the edge
of
the diffuser disc (5). On low capacity the adjustment ring
is
advanced and on high
capacity
r~tracted.
If
the adjustment ring is set too far forward, the combustion air
velocity in the combustion head
is
too high, the ignition
is
more difficult or there is
not enough air to support the combustion (high CO content).
If
the adjustment ring is
too far back, the combustion air velocity is too low and the combustion characteristics
become worse
(02 content is too high).
