- To check the accumulation of coal dust or other waste in the tank chamber and in the feeder tube, and to remove it.
- To examine the state of the air nozzles and to check if the air exhaust holes are free.
It is essential that the above-mentioned operations are also performed at the end of the heating
season.
5.2.4 STOPPING THE FEEDER – GENERAL REMARKS
If the boiler together with the feeder is stopped, the following actions should be necessarily performed:
- Once in three months the user should set the feeding screw in motion for 15 minutes. It prevents the feeding screw
from being blocked inside the feeding tube.
- The user should clean the feeding tube of the remains of the fuel, empty the fuel bunker, clean the retort, unscrew the
bottom lid, remove ash.
5.2.5
MAINTENANCE OF THE FEEDER
The feeder is constructed in such a way that it does not require expensive maintenance. From time to time the feeder
should be cleaned of dust or of the remains of fuel or ash. The engine shell should also be regularly cleaned. The reductors
are filled with synthetic oil, intended to be used throughout the whole boiler operation time, so in fact they do not
require any particular maintenance except for cleaning of the outer parts. No solvents should be used for cleaning, as
they may damage sealing rings and gaskets.
Engine conservation:
in accordance with the operation and maintenance manual for engine.
Fan conservation:
in accordance with the operation and maintenance manual for central heating boiler – at least once
in three months with vacuum cleaner!
5.2.6 BOILER
STOPPAGE
1. The automatic stoppage of the boiler is caused by break in the fuel supply or by the lack of power supply lasting longer
than 4 hours. In such instances the control system is automatically switched off. Before the summer break time the
boiler should be cleaned and all its doors should be left open. Draining the water from the boiler for the summer break
time is unacceptable.
2. Emergency stoppage of the central heating boiler means the switch-off of the control system and the removal of the
heat from the retort furnace.
During the break in the heating season water should not be drained from the boiler and from the
whole heating system.
5.3 CLEANING OF THE BOILER
To maintain the highest efficiency of the boiler, the combustion chamber and the convection channels should be kept
clean. The fuels used to operate the boiler (coal) produce various tar substances in the process of combustion. Cleaning
is essential for the proper work of the boiler and for the proper combustion process.
It is essential that before cleaning the boiler the power supply of the boiler must be switched off.
Ash and soot should be carefully removed from the furnace chamber.
Cleaning of the exchanger should be done through the upper washout hole; soot and ash deposits should be removed
