Firing rates

During operation, burner output varies between:
– minimum output : area A
– maximum output : area B
The work point may be found by plotting a vertical line from the
desired delivery and a horizontal line from the pressure in the
combustion chamber.
The intersection of these two lines is the work point which must
lie within area A, for MIN output, and within area B, for MAX out-
put.
In order to utilize also area C (RL 130/M) it is necessary to per-
form the calibration of the combustion head as explained on
page 22.
The firing rate value (Fig. 3) has been obtained
considering an ambient temperature of 20 °C, an
atmospheric pressure of 1013 mbar (approx. 0 m
above sea level), and with the combustion head
