•
Feed fan,
smooth regulation
(0% to 100 %)
.
•
Telescopic pull-out system of burner
Pell for easy maintenance
2.3. Safety devices of pellet boiler-and-
burner
A complex of safety devices provide for
the safety of the appliance. Air-feed fan,
step –regulated, controls the combustion
according to energy needs and is
maintained in optimal working order.
Independent STB thermostat shut-off the
burner and shut off the fuel feeding in
the combustion chamber in case of rising
boiler temperature.
•
Elbow-shape feeder chute.
The
geometrical shape of burner feeder
chute prevents backfire entry from
burner into pellet hopper. The flexible
tube is melted at a temperature above
80°C. Thus prevent access to the hopper
of the fire.
•
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 (BB Alarm).
•
Fuse
. In case of electrical fault in the
system of the burner (short circuit,
current overload, etc.), the overload is
borne by the electrical fuse fitted on the
main control panel of the burner (10 А).
•
Power
interruption.
Innovative
controller
.
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.
2.4. Design of pellet auger
The auger transports pellets from fuel
hopper to burner. Auger elements are:
auger pipe, auger hose, motor, conveyor
belt for moving the pellets.

2.5. Design of fuel hopper FH 500-V2
Pellet hopper, designated to serve
biomass pellet-fired boilers. Pellet hopper
design allowing installation by choice
on either side of boiler. Made of cold-
rolled steel sheets with PVC coating.
Comfortable pellet charging hatch . Pellets
inside hopper are fed into auger in order
of reception. Precision leveling of hopper
possible via screw-in legs. Inspection side
openings for easy emptying and cleaning
of fuel hopper.
The hopper capacity is determined using
as calculation base the daily or weekly
fuel consumption rate of burner. The
pellet hopper usable volume of 500 litters
allows charging of 280-300 kg of pellets
with diameter 6-8 mm, and top-up/refill
once a week (for burner of rated power
up to 40 kW).
