摘要： 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 method comprises the steps of igniting and, with the application of an ignition air flow, burning the fuel fed into the combustion chamber of the burner, monitoring the formation of flame in the combustion chamber and, after flame formation has completed, starting the in-feed of fuel and, in specific cases, additives and the flow of primary air for sustaining the burning of fuel and also starting the flow of secondary air with the purpose of retaining solid particles, controlling the in-feed of fuel and, in specific cases, of additives and controlling the flow of primary and secondary air depending on the temperature of hot water generated in the boiler such that the in-feed of fuel and, in specific cases, additives, and the flow of primary and secondary air are stopped if the temperature of hot water exceeds a preset limit, and are restarted if the hot water temperature falls below a preset limit. The invention is essentially characterised 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. An intermediate space is formed between the outer jacket (21) and the inner wall, with the intermediate space being interconnected with the combustion chamber such that air can flow between them, and with an opening being disposed on the rear wall (24), and a connection piece (27) is attached to the opening, where said connection piece (27) is adapted for the in-feed of fuel. First, ignition air is fed into the burner (2), with primary air (33) being subsequently fed into the burner (2) for sustaining the burning of fuel. Secondary air (34) and purging air (35) are also fed into the burner (2).
