COMBUSTION HEAD ADJUSTMENT
At this point of the installation, nozzle and pipe
coupling are fixed to the boiler as in fig. (C) p. 5.
The setting of the combustion head depends
exclusively on the output of the burner in the
2nd stage - in other words, the combined output
of the two nozzles selected on page 6 is a par-
ticularly simple operation.
Turn screw 1)(A) until the notch on the sheet
2(A) is level with the plate 3)(A).
Example
The TECNO 34-L Model with two 3.00 GPH
nozzles and 12 bar pump pressure.
Find the delivery of the two 3.00 GPH nozzles in
table (A), page 6:
12.7 + 12.7 = 25.4 kg/h
(corresponding to 300 kW).
Diagram (B) shows that for an output of 25.4 kg/h
the burner TECNO 34-L needs a combustion
head notch regulation 3 approx.
Note
If the pressure in the chamber is equal to 0 mbar,
the air must be adjusted with reference to the
D3910
hatched line on the diagram (B).
Once the regulation of the head has been con-
cluded, refit the burner 4)(C)p.5 on the guides
3)(C)p.5 at approximately 100 mm from the pipe
coupling 5)(C).5, insert the electrode cables and
then slide the burner as far as the pipe coupling.
Replace the screws 2)p.5 on the guides 3)p.5.
Fix the burner to the pipe coupling with the
screw 1)p.5.
Attention
On closing the burner on the two guides it is
advisable to gently pull the high voltage wires
outwards until they are under slight tension.
