A biomass pellet burner is a type of device that is used to burn biomass pellets to generate heat. Biomass pellets are typically made from wood, agricultural residues, or other types of biomass. The burner is designed to be used in conjunction with a heating system such as a furnace, boiler or stove, to provide heat for a building or other application. The burner typically consists of a hopper, where the biomass pellets are stored, and a combustion chamber where the pellets are burned. Air is supplied to the combustion chamber through a fan or blower, and the combustion process is controlled by adjusting the supply of pellets and air.

The heat generated by the combustion process is transferred to the heating system, which is connected to the burner through a heat exchanger. The heat exchanger is typically a series of tubes or plates that absorb the heat and transfer it to the surrounding air or water. Biomass pellet burners are often used as a replacement for fossil fuel burners, as they offer a more sustainable and environmentally friendly option for heating. They can be used in a range of applications, including residential, commercial and industrial settings, and can provide significant cost savings over traditional fossil fuel heating systems.
