Description of the construction of automatic pellet burner of series
“GP”
3.1.
Main properties
The pellet burner of series “GP” consists of the following elements/modules:
The basis part of the pellet burner is the
main unit
, which consists of:
Combustion chamber,
which forms combustion domain and
optimal environment for solid biomass combustion, is designed of
high quality stainless steel;
Grate of the combustion chamber,
which could be easily
detached and reveals access for ash removal;
Air duct
, which uniformly distributes the airflow and ensures safe
cooling of the elements of the burner;
Electric heater
, which heats and ignites the fuel. The heater is
positioned beneath the inclined plate of the grate in the combustion
chamber;
Air supply fan,
equipped with Hall sensor for rotation speed
monitoring;
Photosensor,
which monitors the intensity/presence of the
combustion process, installed aside of the combustion chamber for
easy access and cleaning;
Alarm thermo-probe,
which stops and blocks burner operation in
case of “back fire” process in the fuel delivery pipe;
Control board,
which monitors and controls the operation of the
burner and indicates its status;
Transport auger connector
, which realizes power supply to the
electric motor of the auger;
Interface panel,
which is equipped with light indicators and
thermal capacity control gauge
;
Lever for manual adjustment of the air flow rate,
which is color
synchronized with the position of the potentiometer, which defines
the thermal capacity of the burner;
Transparent window,
though which the operation of the control
board could be checked without removing the cover and any
interventions;
