14. BOILER MAINTENANCE AND REPAIRS
The contractor ensures regular checks and boiler maintenance. During boiler operation, it is
necessary to check water pressure, door tightness, chimney flap tightness, exchanger cap
tightness, chimney tightness and fan performance.
NOTE:
Before boiler shutting down during summer season, clean combustion chamber properly
not to leave any condensed moisture there and open bottom door and chimney flap.
14.1 Door tightness:
Boiler door are stabilized in three points, on two revolving pins and
on closing. If door does not fit tightly, besides revolving closing it is
also possible to fix it from hinge side. You can slightly turn hinge
bolt with releasing and turning nuts and thus you turn door in a
desired direction. In case of sealing rope exchange “1” is a
connecting point.
14.2 Chimney flap tightness:
When cleaning exchanger pipes (Pic. 3/24), check if flap closes tightly. Check chimney flap
(Pic. 3/16) for the same as well. Leakage may result in decreased boiler output.
14.3 Heatproof nozzle
Heatproof nozzle is block made of heatproof concrete used to mix gases
with secondary air and so efficient burning is in progress. Nozzle is located
on water cooling rack. Nozzle is surrounded with heatproof concrete in the
same height as nozzle.Nozzle lifetime depends from mechanical damage
during fuel adding or poke the fire. Therefore, the nozzle is considered as
spare part. Cracks on nozzle are not reason to nozzle exchange, this is
necessary only when nozzle drops. If the nozzle is damaged, its necesary to remove bits and
pieces of old nozzle and then insert new nozzle int the hole. Check if new nozzle fits in the hole.
