摘要： A burner for a heater, especially for motor vehicles, has an essentially axially symmetrical combustion chamber, a burner nozzle for supply and atomization of fuel, a fuel needle for supplying fuel to the combustion chamber, a combustion air supply for supplying combustion air to the combustion chamber, a starting zone in which ignition of the fuel to start the burner takes place, a heat shield between the burner nozzle and the combustion chamber, the heat shield having openings for supplying secondary air to the combustion chamber, and a baffle plate located in the combustion chamber. By choosing the inside diameter of the fuel needle, the exit speed of the fuel is predetermined such that, during the starting phase of the burner; fuel in essentially unatomized form reaches the starting zone. The openings have air guide elements, and the baffle plate has a defined curvature in the axial direction.

摘要： A fuel burner system comprises an air-atomizing fuel nozzle, an air compressor, liquid and gaseous fuel sources and a valve in the delivery line from the liquid and gaseous fuel reservoirs to the nozzle to select the type of fuel (i.e. liquid or gaseous) delivered to the nozzle in accordance with one aspect of the disclosure. The liquid fuel source may be a reservoir which is pressurized by the air compressor to deliver the fuel to the air atomizing nozzle. In addition, the vacuum side of the air compressor may be periodically connected to the fuel reservoir through suitable valving to provide an automatic reservoir refilling capability. The air compressor then acts not only to supply atomization (primary) air, but also to deliver liquid fuel to the nozzle during the liquid fuel burning cycle, and to draw liquid fuel from a remote liquid fuel supply source during the liquid fuel reservoir refilling cycle. A flame spreader is employed in combination with the air-atomizing nozzle according to another aspect of the disclosure to stabilize and shape the flame. The position and diameter of the flame spreader are set to provide optimum fuel burning characteristics.

摘要： Gas fired radiant emitter having a premixing chamber for preparing a premix of gas and air; a perforated ceramic plate acting as burner deck; and a pilot burner having a premix gas supply flow tube and two electrodes. The premix gas supply flow tube of the pilot burner extends from the side of the perforated ceramic plate where the premixing chamber is located, into a through hole in the perforated ceramic plate. The premix gas supply flow tube has a gas exit in the through hole in the perforated ceramic plate or at the combustion side of the perforated ceramic plate. The gas fired radiant emitter has features so that in an area of the perforated ceramic plate around where the premix gas supply flow tube extends into a through hole in the perforated ceramic plate, no premix gas flows through the perforated ceramic plate.
