Abstract
The object of the invention is a method for the automatic combustion of solid granular fuels, particularly pellets, in a boiler having a water-heating heat exchanger, a burner, an air inlet and a' flue gas outlet duct. The invention is essentially characterized by feeding primary air into the burner in such a way that particles of fuel and, in specific cases, additives are floated in the combustion chamber, feeding secondary air into the burner in a manner that it forms an air curtain closing off the open end of the combustion chamber, and also feeding purging air into the burner after the in-feed of fuel and, in specific cases, additives has been stopped, with the purging air passing along the inner wall of the combustion chamber following a spiral-shaped path and sweeping over the wall of the combustion chamber. The method is carried out utilizing a boiler having a burner that comprises a combustion chamber that is surrounded by an outer jacket (21), covered by a cover (39), bounded by an inner wall and terminated by a rear wall.
