How does a modern pellet burner work?

The modern pellet burner - a guarantee of economy and warmth

Pellet burners seem like simple devices, but the real difference is in the control. Whether the combustion is stable and economical or just “burns”, you will learn now. Today you will understand how a modern pellet burner works, how the fuel is supplied, how the air is controlled, how the flame is stabilized and why the entire system can be both reliable and economical. As an example, we will use a pellet burner from the RB series to show the real construction from the inside, the focus of the article is the technology of the burner, not the specific model.

What makes a modern pellet burner different?

The pellet burner is an automated system that controls the amount of fuel, the amount of air, the burning rate and the power. It is this control that allows for much cleaner and more stable combustion compared to classic stoves and manual boilers.

Fuel supply and ignition

The fuel is fed through a screw mechanism, the most important thing is that the dosage is uniform. Too many or too few pellets lead to an unstable flame, while in a well-tuned system the screw feeds fuel at precisely defined intervals to maintain an optimal layer in the combustion chamber.

Ignition is carried out by a heater, which heats the air in the chamber to a temperature sufficient for ignition. The process depends on the pellets, air and settings, and the key is that the ignition is repeatable and stable, which is a priority in the RB design.

Basic combustion and air control

After ignition comes the main combustion, where the fan controls the air and maintains the correct air-fuel ratio. This is crucial for clean combustion, low emissions, a stable flame and high system efficiency. Modern burners rely on electronic control, not mechanical regulators, and do not operate at full power all the time. They modulate their power according to the needs of the system, which reduces pellet consumption, lowers the temperature of the exhaust gases and extends the life of the components.

For even greater comfort, Greyko RB Star models can be equipped with a Wi-Fi module, which allows: Remote change of settings, Monitoring of operating mode, Monitoring of temperature and consumption, Management from a smartphone or tablet. No matter where you are – you have full control over your heating system

The RB has three levels of modulation to avoid the stressful start-stop cycle. Self-cleaning is the last but key element. Accumulated ash is flushed out by the newly fed pellets without interrupting the combustion process, which maintains stable operation and reduces the need for manual intervention.

Its great advantage is that it can be installed directly on: Solid fuel boilers, Oil boilers without additional conversions. It is available in capacities of 20, 30, 50, 70 and 100 kW, which makes it suitable for sites with an area of 150 to over 1200 sq.m.

Why choose Greyko RB? Proven reliability, Intelligent automation, Compatibility with various fuels, Low consumption and real savings, High safety, Convenience and remote control. Greyko RB burners are designed for customers who want quality, economical and trouble-free heating, without daily maintenance and unnecessary costs.
