Application Of The Burner To Boiler - baltur BT 250 DSG 4T Manual Del Usuario

CONDITIONS FOR GOOD INSTALLATION
E
N
Before proceeding with installation, check that:
1) The chimney (cross section and height) complies with the boiler
G
manufacturer's instructions and local standards.
2) When it is necessary to make a refractory lining for the com-
L
bustion chamber (if the type of boiler requires it), then it must
be made according to the specific instructions of the boiler
I
manufacturer.
3) The electric power supply line for the burner should be ac-
S
cording to our diagram and the electrical connections on the
H
burner should match the voltage of the electric power supply
line.
4) Fuel pipelines should be made according to our diagram.
5) The nozzle(s) fitted on the burner should be suitable for the
boiler capacity; replace them with others if necessary. In no
case should the quantity of fuel delivered exceed the maxi-
mum amount required by the boiler and the maximum amount
permitted for the boiler. Remember that the combustion head
has been designed for nozzles with a 45° spray angle. Only

APPLICATION OF THE BURNER TO BOILER

1 Boiler plate
2 Flange with insulating materials
3 Seam with insulating materials
4 Burner securing flange
5 Stud bolts, washers and nuts for fastening to the boiler
6 Nuts screws and washers to fasten flange to the sleeve
COMBUSTION HEAD ASSEMBLY
To put in place insulation flange 2, which must be positioned betwe-
en the burner and the plate of boiler 1, the end of the combustion
head must first be removed.
a) Adjust position of connector flange 4 by loosening screws 6
so that the combustion head penetrates into the combustion
chamber the amount recommended by the generator's manu-
facturer.
b) Position seal insulation 3 on the tube unit.
c) Fasten the combustion head assembly to the boiler 1 using the
stud bolts, washers and the nuts provided 5.
d) With suitable material, completely seal the space between the
tube unit of the burner and the hole on the refractory plate
inside the boiler door.
in special cases can nozzles with a different spray angle be
fitted; in these cases, however, make sure that the nozzle
with a different spray angle will not cause problems (flame
separation, disk or combustion head fouling, violent ignition,
etc.).
6) When removing the protective plastic cap from the nozzle seat
be careful because if the sealing surface is indented (a slight
scoring would be enough) it will cause fuel dripping.
7) Make sure that the burner head enters the combustion chamber
according to the boiler manufacturer's instructions.
8) Before connecting the flexible pipes, remove the plastic pro-
tective caps from the pump fittings.
