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.
Convection channels, where ashes are tend to gather should be cleaned
systematically, every 3÷7 days. For this purpose the boiler is provided with tools.
Convection channels cleaning is performed using washout wholes placed in the
upper part of boiler. Once cleaning operation is accomplished, whose holes should
be closed. Forming dust should be removed using door of side wall washout opening.
Failure to follow these recommendations may result in high heat losses, and render
difficult gases circulation in consequence make smoke coming out of boiler. In case
of using a fuel prone to sticking during combustion process, it may lead to
agglomeration and slug forming in the area of retort rim and combustion chamber
wall. In such a case, the obstacle should be pushed down into an ash drawer.
Systematic maintenance extends boilers life and its auxiliary equipment. Cleaning the
chimney duct is not less important.
NOTE: At least a month the quantity of slung in retort should be controlled. If
required, put out a boiler and clean retort-furnace.
7.4. END OF HEATING SEASON
Once heating season is finished, or when switching off the boiler is scheduled, the
controller should be then switched off and the glowing batch should be removed from
retort and push into ash box chamber.
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 of combustion chamber and all movable
elements with oil.
For the period of brake time, water should not be drained out of boiler and
installation. In the controller manual mode, switch on a feeder allowing it to slide the
glow into ash container.
If the boiler is not employed, once a week a feeder mechanism should be put to
work. This preserve the screw elements not to be blocked inside a pipe.
NOTE: it is not allowed to put out the fire with water when in the boiler’s room!
7.5. TERMS OF SAFE EXPLOITATION
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,
