This manual contains a record of the essential
information and will have been completed by the
commissioning engineer with individual details of
the burner. These details should be verified
periodically and adjusted if variations are noted.
Commissioning details must also be recorded in
the
appliance logbook

The Performance Graph shown on page 15 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
normally 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, i.e. 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.
