The burner is an extremely important element in the structure of a pellet boiler, because it is where the key combustion process of fuel fuel takes place. With dynamic technological progress, significant improvements have been made not only in the boilers themselves, but also in the burners used in them. These innovations have made these devices much easier to operate.
Burners in pellet boilers are equipped with a grate made of high-quality heat-resistant and heat-resistant steel, and with an electric igniter that starts the fire automatically in accordance with previously set parameters. Inside modern burners there are also a number of additional components that manage and monitor the processes of ignition, combustion, fire extinguishing, fuel supply, and air blowing, etc. Importantly, each burner is equipped with a fire protection system, which significantly affects the efficiency and performance and operational safety of the heating device. Thanks to this system, combustion takes place efficiently, without the need for frequent interference from users.
There are several types of burners adapted to pellet boilers. Due to the type of grate, they are divided into burners with a fixed grate and the so-called ash scraper, movable grate burners and rotating grate burners.
The burner operation is controlled by advanced controllers, which enables automatic combustion. It is worth emphasizing, however, that users retain the option of manual tanning, for example using a traditional grate, in case of emergency situations. At a later stage of operation, additional functions are also important, such as temperature sensors or mechanical thermals, which automatically turn off the device if the set temperature is exceeded. Another important aspect is mechanical protection against flashback, e.g. using the so-called cells.
Self-cleaning burners deserve special attention in modern pellet boilers. This innovative solution significantly facilitates the operation of the device, and the technology used has a positive effect on the efficiency of the combustion process, resulting in lower fuel consumption.
