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 193 kg/h) 1
st
and 2
nd
nozzle are not equal to the 3
rd
one. Follow this procedure in
order to obtain higher values of CO
2
(during 1
st
and 2
nd
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 1
st
and 2
nd
stage.
SUGGESTED NOZZLES.
(1) The pump pressure is referred to all three nozzles operating, the pressure increases automatically with two nozzles
in operation and more with only one.
