4 CONSTRUCTION DESCRIPTION OF AUTOMATED WOOD PELLET BURNER FROM
SERIES “GP 45 IV”
4.1.
GENERAL CONDITIONS
The pellet burner from series “GP 45 IV” consists of the following components/modules:
The main part of the system is a main module that consists of:
Combustion chamber, which forms the conditions for optimal burning process
and is made of high quality stainless steel;
Combustion chamber fire-grate, which is easy removable and provides
availability for cleaning of the ash deposits;
Air distribution tract, which provides uniform supply of firing air and also air for
cooling of the burner’s parts;
Electrical heating element, which serves for primary ignition of the fuel,
positioned in the combustion chamber under the tilted part of the fire-grate;
Firing air supply fan, equipped with sensor for reading the rotation frequency
and availability for regulation;
Photo-sensor for monitoring of the burning process, mounted on the burner’s
side for its easy cleaning;
Emergency temperature sensor for protection from the so called “back fire” in
the main module’s fuel inlet pipe;
Control module for monitoring and managing the burner operation;
Display module with keyboard, used for visualization of the burner operation
mode and for performing all necessary adjustments;
Connector for the fuel transport auger, used for the auger power supply;
Reversible thermo-sticker, used for monitoring of the temperature in specific
zone of the burner and for evaluating the necessity for cleaning of the
appliance to which it is mounted, or for evaluating the necessity of inspection
of the chimney draught;
Irreversible thermo-sticker, for indication of registered overheating of the
burner, precondition for warranty claim denial.
Electrically driven outer transport auger, which transports the fuel from a hopper to
the burner, depending on the burner operation mode. The auger consists of motor-
gear with electric motor, equipped with integrated overheating protection, pipe for
transferring the fuel to the drop hole (where it drops down by gravity) and to the
flexible pipe;
Flexible pipe, made of special transparent thermo-resistant material (in case of fire it
does not separate harmful or toxic substances), which connects the auger and the
main module.
The main burner modules and their positioning are presented in Figure 4.1.
