MULTIBLOC VALVE ADJUSTMENT
Max working pressure p
Max permissible working pressure at which all functions are assured.
Intake pressure range p
Range between minimum and maximum intake pressures that gives optimum performance.
AIR pressure p
L
Pressure generated by the fan. Air pressure influences total gas delivery rate. This pressure is a reference value
for pressure at the burner p
GAS pressure at burner p
Gas pressure measured upstream from the mixing device. Pressure measured after last component of the train.
Average pressure p
a
Pressure at outlet from pressure regulator measured before valve V2.
Combustion chamber pressure p
Pressure in the combustion chamber.
Combustion chamber pressure (positive or negative pressure) may vary as it is influenced by:
- power
- dirtiness
- variation of cross-sections
- atmospheric conditions (etc.)
Combustion chamber pressure counteracts the combustion air flow. It must therefore be considered as a disturbance
factor. By adjusting the ratio to V = 1:1 this disturbance factor becomes negligible as the pressure in the combustion cham-
ber has an equivalent effect on both the air and gas total delivery rates.
