7.3 CLEANING THE BOILER
In order to use fuel in the safe manner, and to get declared boiler’s power and heat
efficiency, keeping adequate cleanliness of combustion chamber and convection
channels is indispensable.
As far as furnace chamber of the boiler is considered, special attention should be
paid when removing ash and slag from between grate orifices and chamber’s walls.
Such a cleaning should be exercised prior each boiler’s fire up process, but not
less than after 150÷260 of boiler’s continuous work. Cleaning of convection
channels, with volatile ashes residues, should be performed every 3÷7 days,
depending on quality of burned fuel. The cleaning operation is done through
washout holes indicated on the drawing (p.12, p. 15, 17). Once cleaning is
finished, those wholes should be sealed tightly.
Cleaning the chimney duct is not less important. In case of low temperatures in
boiler in the longer time, it is necessary to “heat” the boiler periodically (at least
once a week) (burning-out in temperature 70÷80°C). This is imp ortant for extending
the durability of boiler.
7.4 END THE HEATINHG SEASON
Once heating season is finished, or in other cases of scheduled stops, wait
the fuel to be completely burned out. Once boiler is out and cooled down, remove
from the furnace all remains of burned fuel and apply cleaning and conservation of
the entire boiler. Pay special attention to lubricate inner partitions and movable
elements with oil.
For the period of brake time, water should not be drained out of boiler and
installation. If boiler’s stopping took place in emergency conditions, glowing fuel
shell be removed into metal box and taken out of boiler room, or alternatively the
gloving fuel may be covered with sand.
NOTE: it is not allowed to put out the fire with water when in the boiler’s room!
In order to maintain safe operation of boiler following rules need to be exercised:
keep the boiler in good technical condition and its installation, in
particular take care of the installation tightness, as well as keep sealed
door and washout openings,
keep boiler room tidy, do not stack any objects not related to boiler’s
operation,
in the winter time do not apply brakes in heating process, preserving water
in installation against freezing. Especially, if the safety pipe is
frozen (overflow pipe) it may be very dangerous because of potential
damage of boiler,
it is forbidden to fire up a boiler by use of petrol, kerosene,
solvents, explosion may occur causing he operator to be burned
