OZZLE

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.

comprehensive stock making up the burner systems

described  in  this  handbook.  Should  it  become

necessary  to  order  replacement  parts,  it  is

important to quote the burner model, specification

and  serial  numbers  to  ensure  correct  expedition

of your order.

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

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.
