MULTIBLOC VALVE ADJUSTMENT
MB-VEF
Adjustment range
Max working pressure p
max
Max permissible working pressure at which all functions are assured.
Intake pressure range p
e
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 .
Br
GAS pressure at burner p
Br
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
F
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 chamber has an equivalent effect on
both the air and gas total delivery rates.
