3. Description of the construction of automatic pellet burner “ERATO
GP20+”
3.1. Main properties
The burner 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;
• On-position switch (safety sensor), which stops and blocks the
burner operation if it is detached from the appliance- heat energy
consumer;
• 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;
• Transparent window, though which the operation of the control
board could be checked without removing the cover and any
interventions;
