Pellet burner – the heart of your boiler

Have you decided to heat with pellets? Good decision. It is an ecological and economical fuel.

If your household generates a lot of wooden waste, you can even produce it on your own. When the granulate is ready, nothing remains but to put it into the boiler and enjoy its efficiency. This is where today’s hero comes into the spotlight – a pellet burner.

What is a pellet burner? 

A pellet burner is a key element of a boiler – it is responsible for the combustion process of the granulate and, consequently, for generating heat. In addition, the burner is responsible for dosing the fuel material and maintaining the desired combustion conditions.

How does it work?

Thanks to a special mechanism controlled by the boiler controller, the pellet is introduced into the combustion chamber in the appropriate amount. Most often, this is handled by the so-called screw feeder powered by electricity. 

The fuel supply is adjusted to the current heat demand. The mechanism operates in such a way as to achieve the highest possible efficiency without unnecessary excess fuel consumption. 

This process can be fully automated.

The next stage is pellet ignition. When the appropriate amount of granulate is already in the combustion chamber, an electric igniter or a gas flame initiates the combustion process.

Combustion takes place in the chamber, where as a result of this process hot air or gas is generated, which transfers heat to the heat exchanger located in the boiler.

Most burners allow adjustment of combustion parameters during the process itself.

Manual adjustment of the amount of fuel supplied or regulation of airflow allows for the most efficient combustion with the lowest possible granulate consumption.

During the entire combustion process, parameters from inside the chamber are monitored by the boiler controller. It is the controller that relieves us of the task of adjusting combustion parameters. Thanks to a properly configured controller, we are able to achieve a safe and economical combustion process and use one hundred percent of the energy potential of the pellet.

Thanks to a properly configured pellet burner, it is also possible to reduce the emission of harmful substances into the atmosphere. 

Why is it worth using a pellet burner?

Heating with pellets has many advantages. One of them is the fact that we can produce it ourselves. With the help of a pellet machine, we are able to create fuel from agricultural waste and biomass that would otherwise require disposal. (To learn more about independent pellet production click here) In this way, we save both resources and money. This option also guarantees independence from the supply chain. The combustion of granulate itself generates far fewer harmful fumes than in the case of other fuels – especially fossil ones. In this respect, pellet is an eco-fuel.

A properly configured boiler, with a suitably selected burner and a well-adjusted controller, will have a positive impact both on the air quality in our area and on the condition of our wallet.
