CHOICE OF NOZZLES FOR 1st AND 2nd
STAGE
The burner complies with the emission require-
ments of the EN 267 standard.
In order to guarantee that emissions do not vary,
recommended and/or alternative nozzles speci-
fied by Riello in the Instruction and warning
booklet should be used.
Warning: It is advisable to replace noz-
!
zles every year during regular mainte-
nance operations.
Caution: The use of nozzles other than
!
those specified by the manufacturing
company and inadequate regular maintenance
may result into emission limits non-conforming
to the values set forth by the regulations in
force, and in extremely serious cases, into
potential hazards to people and objects.
The manufacturing company shall not be liable
for any such damage arising from nonobser-
vance of the requirements contained in this
manual.
Both nozzles must be chosen from among those
listed in table (A).
The first nozzle determines the delivery of the
burner in the 1st stage.
The second nozzle works together with the 1st
nozzle to determine the delivery of the burner in
the 2nd stage.
The deliveries of the 1st and 2nd stages must
be contained within the value range indicated on
page 2.
Use nozzles with a 60° spray angle at the rec-
ommended pressure of 12 bar.
The two nozzles usually have equal deliveries,
but the 1st stage nozzle may have the following
specifications if required:
• a delivery less than 50% of the total delivery
whenever the back-pressure peak must be
reduced at the moment of firing;
• a delivery higher than 50% of the total deliv-
ery whenever the combustion during the 1st
stage must be improved.
Example with TECNO 34-L
Boiler power = 270 kW - efficiency 90%
Power required by the burner =
270 : 0.9 = 300 kW
300 : 2
= 150 kW per nozzle
therefore, two equal, 60°, 12 bar nozzles are
required:
1° = 3.00 GPH - 2° = 3.00 GPH,
or the following two different nozzles:
1° = 2.50 GPH - 2° = 3.50 GPH,
or:
1° = 3.50 GPH - 2° = 2.50 GPH.
