8. Boiler’s maintenance
TKAN boiler requires daily and periodical cleaning.
1.
Daily (at least weekly) cleaning also applies to the boiler’s space of grey cast iron where
we, by constantly ejecting ash, enable more efficient operation of the electric heater for
firing and more efficient combustion, that is larger amount of air through air channels
in the grey cast iron. Also, ash starts piling up during the day on the floor, in the area
around the furnace itself. According to average combustion parameters, 100kg of
pellets produce 1kg of ash, but this information significantly varies depending on the
type and quality of ash.
2.
Each 7 to 10 days, shutting down the boiler is recommended, cooling off a few hours,
and manual or, the best, vacuuming depths of the combustion chamber. This removes
even larger pieces of uncombusted pellets which can cause unpleasant sound while the
boiler is working and decrease the lifespan of the screw spiral which pushes pellets into
the combustion space.
3.
Once a month, it is necessary to open the upper door for cleaning as well, remove
turbulators and remove layers of tar and soot from pipes of the exchanger. Everything
removed at that point is picked on the upper surface of the furnace roof or in the
smokebox. Too much ash in pipes of the exchanger decreases utilization of the boiler
and leads to excessive temperatures in the furnace which can cause deformations to it,
that is to the lower door.
4.
Cleaning the multi cyclone should be done once a month. On the case’s sides, there are
two cleaning holes. Remove the lid and thoroughly clean inside the case. Be careful
when returning the lid not to move the sealing tape. Also, clean the centrifugal fan that
has a cleaning hole on the pipe.
5.
Regardless of the automatic dedusting, some parts should be cleaned manually and
those are:
-
a part located under pipe exchangers (can be seen when the upper door is open)
-
some pipe in the exchanger located in corners.
-
Clean periodically, at least once a month.
-
It is mandatory to, once a day, release the water from the compressor’s tank by using
the valve located at the bottom of the tank.
-
It is mandatory to empty the bowl in the FRL unit where condensation (water) is
accumulating.
-
If unit B is installed, it is mandatory to, daily, release the water from the tank by using
the valve located at the bottom of the tank.
6.
Cleaning heater pipes is recommended to be done monthly, cleaning the filter of the
heater in a licensed maintenance department.
7.
The inspection of the turbine’s validity is done yearly and balancing when needed
(when a regular yearly maintenance is done), and balancing the turbine is mandatory
every second year.
8.
The safety valve needs to be calibrated yearly according to the law in a licensed
laboratory specialized in calibrating equipment.
