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 to get the pressure in the combustion chamber and the other one into the butterfly valve’s pressure outlet of the burner. 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 combu-
stion 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.
