1. Automatic pellet burner “ERATO GP20+” – description and advantages
“ERATO GP20+” is automatic pellet burner, which utilizes wood pellets.
The burner is designed to be installed on already operating heating boilers or
other equipment, thus allowing fuel switch procedure to a renewable energy
sources - biomass. The installed burner operates on wood pellets and the
thermal energy, resulting from the intensive combustion process is directed
to the heat exchange surfaces of a boiler or another thermal consumer.
The burner could utilize following types of fuel
• Wood pellets, having diameter 6 and 8 mm, categorized in the range
of: A, AB, B (according to the methodology, developed for pellets
properties estimation in ERATO company);

information to the control unit;
• electric heater, which ignites the fuel;
• combustion chamber, which gives environment for efficient
combustion process;
• removable grate of the combustion chamber, allowing easy access and

• photosensor, which gives information for the status of the combustion
process to the control unit and allows dynamic operation of the burner;
• interface panel, equipped with light indicators;
• the control board is equipped with led indicator for indicating the
status of adjustable parameters index value;
• a variable potentiometer, which allows easy thermal capacity
adjustment;
• a position switch, which confirms that the burner is installed properly
and could work safely;
