• Built-in controller.
The main control unit, located in the
burner, manages the entire heating
process. Controler functions:
Controler functions:
1) fully automated ignition and pellet
feed;
2) self-cleaning function (adjustable 1-6
times over 24 hours at equal intervals),
programmable start time;
3) controls the operation of the
circulation pump of the central
heating;
4) controls the operation of the pump of
the domestic hot water;
5) option for control by room thermostat;
6) timer;
•
Photo-sensor
- monitors the power of
the burner flame
•
Internal auger
•
Dry contactless resistance heater
assuring ignition of fuel
•
Innovative cleaning system
of the
combustion chamber
•
Air feed fan
, step-regulated (0% to
100%).
2.2. Burner safety devices
•
Elbow-shape feeder chute.
The
geometrical shape of burner feeder
chute prevents backfire entry from
burner into pellet hopper.
•
Thermostatic protection
(80°С). The
thermostatic protection is fitted on the
feeder chute. When the surface of the
feeder chute reaches 80°С, the control
stops the feeding of pellets into the
burner and signals for fault.
•
Fuse
. In case of electrical fault in the
system of the burner (short circuit, high
current, etc.), the overload is borne by
the electrical fuse fitted on the main
control panel of the burner (10 А).
•
Power interruption
. In case of power
interruption, all parameter settings are
stored in the memory of the controller.
Upon the subsequent restart of the
burner, the controller resumes the
execution of the program from the
point when the power interruption
occurred.
3. FUEL
All pellets are biomass manufactured
from common low-growing plants and
trees. The most common household type
pellets are made of sawdust and milled
wood chippings which are waste material
from wood used in the production of
logs, furniture and other products. Wood
is the richest raw material which does
not have any impact on the production
costs of food products or ethyl alcohol
(ethanol). The raw material is processed
under high-pressure and temperature
and is pressed to produce small-size
cylindrical pellets. The production
process may utilize soft wood material
(such as softwood, pine), hardwood (oak)
as well as recycled waste wood. Wood
pellets are produced in hammer mills or
wood pellet plants.
Advantages of wood pellets:
Convenient storage.
Pellet bags can be
stored on a small area in a dry garage,
basement, service room or shed.
Easy loading.
In most cases the boiler
hopper needs loading only once a week –
this depends on the hopper capacity.
