are a renewable fuel with minimum
carbon emissions and ultimate burning
efficiency.
•
Automated
. All boiler functions are fully
automated – no human intervention is
needed for the normal operation of the
boiler. Owing to an improved algorithm
with optional adjustment of a wide
variety of parameters, the system may
be finely tuned to any particular heating
system to achieve optimum efficiency
and fuel consumption.
Controller functions:
1) fully automated ignition and pellet
feed;
2) exhaust fan ensures stable operation
of the boiler;
3) boiler-and-burner
self-cleaning
function;
4) controls the operation of central
heating circulation pump;
5) controls the operation of DHW
(domestic hot water) pump;
6) controls by room thermostat;
7) flue gas sensor;
•
Efficient
. To keep from losing heat into
the ambience, the boiler is insulated
on the outside by 100 mm high-
temperature wool. With its state-of-
the-art combustion control system and
cylindrical body design construction the
PelleBurn boiler achieves efficiency rate
of as much as 91%
2.2. Design of pellet burner Pell
The burner is made of high-quality stainless
steel able to withstand temperatures of up
to 1150°С. The burner must be installed on
a heating boiler.
The burner consists of two parts:
combustion
chamber
tube
and
external tube with sheet metal mantle.
Longitudinally, under the housing, there
are blow chamber, fuel ignition heater, fan
and power supply. On the upper part of the
burner there is a feeder chute to which the
pellet auger is attached. The combustion
chamber consists of two tubes:
Ember resistant steel tube inside the
burner with holes for air intake along its
entire length, opening for the hot air from
the fuel ignition heater.
Outer stainless steel tube. Between the
two tubes there is a gap which provides
for free circulation of the air necessary
both for cooling and oxygen supply into
the combustion chamber.
The feeder chute allows 360° rotation
for its best convenient positioning when
connecting the pellet auger to the hopper.

Other elements of the burner are
•
Internal auger.
•
Dry contactless resistance heater
assuring ignition of fuel.
•
Pneumatic cleaning system
of the
combustion chamber.
