The Burnerlance is designed to operate spill-back
atomisers of the non tip shut-off variety, and having
a 9/16 x 24 unef fixing thread.
The Fluidics KC2 series atomiser is the prefered type
and this will have been sized at the point of order
to suit the burner rating and application.
When the nozzle has completed 3000 hours of
operation, it should be replaced with the same
Make, Type and Size
as fitted. Failure to do so will
alter the characteristics of the burner and may
impair the performance and efficiency of the plant.
The nozzle identification code is stamped onto the
face of the hexagonal nut section of the nozzle
body as shown below.
Should any doubts arise concerning the suitability
or performance of the burner nozzle, please
contact the Nu-way Technical dept. who will be
pleased to assist.

The Performance Graph shown on page 19 plots
burner input against the appliance running
resistance. The appliance starting resistance is
derived from a combination of the combustion
chamber shape, volume, start rate and flue
conditions. It may be necessary to select a burner
with a higher fan static pressure than would
normaly be chosen, if the appliance has a high
starting resistance.
Similarly, when firing a reverse pass boiler up to 2
MW, with a combustion intensity of 2 MW/M
3
and
an operating resistance between 40 and 90 mm
wg. it is recommended that a burner with a higher
fan static pressure is selected, ie. if the graph selects
a burner with a 28 cm fan then use the 34 cm fan
model for correct combustion.
All outputs quoted are based on gross C.V.
