Working diagram
The working diagram shows
burner output as a function of
combustion chamber pressure.
It corresponds to the maximum
values specified by EN 267
measured at the test fire tube.
The efficiency rating of the
boiler should be taken into
account when selecting a
burner.
Calculation of burner output:
QF =
Q
N
η
K
QF = Burner output (kW)
QN = Rated boiler output (kW)
η
K
= Boiler efficiency (%)
