    摘要： There are provided a radiant tube burner and a radiant tube capable of reducing the generation of NOx with a simple configuration. A gas injection unit (2A) inserted into a tube (1) having an oval-shaped opening cross section has a secondary combustion air nozzle (21) arranged in a center portion and a plurality of primary combustion air nozzles (22) and a plurality of fuel gas nozzles (23) arranged to surround the secondary combustion air nozzle (21). The opening cross section of the tube (1) is virtually divided into four areas with two straight lines (X1, X2) as the boundaries, the two straight lines (X1, X2) being obtained by tilting a minor axis (X) which is the axis of the short diameter of the oval by ±45° with the center of the oval as a center (P), and the flow rate of primary combustion air injected from the primary combustion air nozzles (22) located in the areas containing the minor axis (X) of the oval is lower than the flow rate of the primary combustion air injected from the primary combustion air nozzles (22) located in the areas not containing the minor axis (X) of the oval.

    摘要： A combustion device (100) includes at least one burner (30), an infrared reflective plate (40, 60, 90), and an infrared ray generation mesh (20). Wherein, the at least one burner (30) includes a flame outlet (32); the supporting assembly (10) includes a cover plate (121) which has an opening (122) corresponding to the flame outlet (32) and a plurality of holes (124); the infrared ray generation mesh (20) is disposed on the supporting assembly (10) and is heated by the flames out of the flame outlet (32) to generate infrared rays; and the infrared reflective plate (40, 60, 90) has a reflective surface (401a, 601a) for reflecting the incident infrared rays out of the infrared ray generation mesh (20) is disposed between the rear cover (14) and the infrared ray generation mesh (20). Whereby, the combustion device (100) is favorable to generate stronger and more uniform infrared rays.

    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.
