What are the main characteristics of pellet boilers?

The pellets can be used in boilers or boilers specially designed chips. Typically the pellet boilers are automated, of great simplicity of use and capable of providing a high level of comfort.

The pellet boilers are equipped with a container for the storage of the fuel located near the boiler, hence the pellets are picked up by a screw conveyor that transports them into the boiler for combustion. The burners for pellets are applied on the front of the boiler and are fed from above, the fuel burns generating a horizontal flame that is projected into the boiler.

The ignition, by means of an electrical resistance, is automatic and very rapid.

In more advanced systems the adjustment of combustion air and fuel flow are carried out automatically by means of a microprocessor.

For the safety of a pellet boiler there are measures to prevent the return of the burner flame to the tank, the most common method is to place between the auger and the boiler of a sudden (hose) free fall of the pellet.

Boilers for pellets and small dogs are equipped with a fuel tank capacity limited to a few hundred liters in the most economical systems this container is loaded by hand svuotandovi bags of pellets. However the autonomy of operation, even with these machines simpler, is a few days.
