WORKING RANGE
COMBUSTION CHAMBER PRESSURE MAXIMUM OUTPUT
(in compliance with DIN 4788)
MINIMUM GAS PRESSURE - OUTPUT
Pressure
: detected at the pressure test-point 8) (fig. 1) with nil mbar into the combustion chamber.
Should the combustion chamber be pressurized, the pressure necessary will be that of the
graph plus the pressurization value.
Example
: to obtain 800 kW it is necessary a gas pressure of 11 mbar and the combustion head set as
indicated at page 7.
If the combustion chamber is pressurized at 2 mbar, the pressure detected at the test-point
8) is: 11 + 2 = 13 mbar.
If this value is too high, for very low gas pipework pressures, the gas gear 6) (page 7) could
be more open.
Do not decrease the pressure at the coupling under the values shown in the diagram.
Output
