•Thermostac protecon (80°С). The
thermostac protecon is ed 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.
•Temperature safety valve with sensor
on screw mechanism. Temperature
safety valve is connected to a water
tank.
•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 ed on the main
control panel of the burner (10А).
•Power interrupon. In case of power
interrupon, all parameter sengs are
stored in the memory of the controller.
Upon the subsequent restart of the
burner, the controller resumes the
execuon of the program from the
point when the power interrupon
occurred.
•STB - emergency thermostat (with
probe inserted into the socket of the
boiler). When boiler temperature is
increasing above 100°C, the STB –
thermostat stop the operaon of feed
screw.
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 producon of
logs, furniture and other products. Wood
is the richest raw material which does
not have any impact on the producon
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 producon
process may ulize so wood material
(such as sowood, pine), hardwood (oak)
as well as recycled waste wood. Wood
pellets are produced in hammer mills or
wood pellet plants.
Advantagesofwoodpellets:
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.
Beercontroloffuelquanty. The small
size of the pellets allows for precise fuel
feeding. On the other hand, the supply
of air for reaching opmal combuson
eciency is easier to adjust since the
fuel quanty in the combuson chamber
remains constant and predictable.
