CHOICE OF: NOZZLES - PUMP PRESSURE -
COMBUSTION HEAD ADJUSTMENT
•State, first of all, the maximum output required with all three nozzles in operation.
•On the base of the maximum required output, choose-from table A or B - three related nozzles.
Nozzles: 60° - Pump pressure: 12 bar
For three-stage operation (up to 116 kg/h) 1st and 2nd nozzle are not equal to the 3rd one. Follow this procedure
in order to obtain higher values of CO2(during 1st and 2nd stage of operation), complying with German Standard
DIN.
•The references on the table C have to be followed in case of need of:
- modification of the pump pressure in order to vary the output;
- diverse composition of the 3 nozzles group;
- knowledge of the output in 1st and 2nd stage.
SUGGESTED NOZZLES
(1) The pump pressure is referred to all three nozzles operating, the pressure increases automatically with two noz-
zles in operation and more with only one.
