Measuring the gas pressure in the combustion head
In order to measure the pressure in the combustion head, insert the pressure gauge probes: one into the combustion chamber’s pres-
sure outlet (Fig. 19-2) to get the pressure in the combustion chamber and the other one into the butterfly valve’s pressure outlet of the
burner (Fig. 19-3). On the basis of the measured differential pressure, it is possible to get the maximum flow rate: in the pressure - rate
curves (showed on the next paragraph), it is easy to find out the burner’s output in Stm
3
/h (quoted on the x axis) from the pressure
measured in the combustion head (quoted on the y axis). The data obtained must be considered when adjusting the gas flow rate.
NOTE: THE PRESSURE-RATE CURVES ARE GIVEN AS INFORMATION ONLY; FOR A PROPER SETTING OF THE GAS RATE,
PLEASE REFER TO THE GAS METER READING.
