Combustion Chamber Fuel Mixing System

A two-stage fuel feeding process — the external feeder delivers pellets into the burner, while the internal feeder doses the appropriate amount of biomass into the combustion chamber. The design of the internal feeder also performs a fuel mixing function. Optimising the combustion process makes it possible to burn pellets with a high ash content. The fuel mixing function also extends the maintenance-free operating time of the burner.
