摘要： PROBLEM TO BE SOLVED: To provide a low NOx radiant tube type regenerative burner for performing two-stage combustion using air dilution natural gas as fuel gas, and also to provide an operating method therefor. SOLUTION: This low NOx radiant tube type regenerative burner uses the air dilution natural gas with an air ratio of 30 to 35% as fuel gas and includes a primary combustion cylinder for two-stage combustion. In the radiant tube type regenerative burner and the operating method therefor, a ratio of the inside diameter (D) of the primary combustion cylinder to the inside diameter (d) of a fuel feed tube satisfies the following equation (A): 3.8≤D/d≤7.7...(A). It is preferable that a distance X between the end of the primary combustion cylinder on the input side of combustion gas and a primary combustion cylinder supporting plate is at least 100 mm.

摘要： PROBLEM TO BE SOLVED: To readily conduct maintenance by packing a large diameter regenerative body in a high temperature side and a small diameter regenerative body in a low temperature side, providing a plate-like partitioning wall between these packed layers and providing a cylindrical partitioning wall to the large diameter packed layer. SOLUTION: A cylindrical partitioning wall 16 which matches with the periphery of a fuel supply pipe 6 or the like is provided to a packed layer of a large diameter regenerative body 2b. The cylindrical partitioning wall 16 is formed between a plate-like partitioning wall 10 and a high temperature side support member 5 without a gap. These partitioning walls 10, 16 can be made of ceramic or the like of high heat resisting material. Accordingly, the large diameter regenerative body 2b is kept at a given position by the plate-like partitioning wall 10, the cylindrical partitioning wall 16 and the high temperature side support member 5, and therefore the fuel supply pipe 6 or the like is not required to be inserted into an inserting port 9 of the support member 5 at the high temperature side. Thus, the large diameter regenerative body 2b is prevented from flowing into a packed layer 3s of a small diameter regenerative body through an inserting port 11 of the plate-like partitioning wall 10, and from flowing outside of a burner through the inserting port 9 of the support member 5.

摘要： PROBLEM TO BE SOLVED: To make the longitudinal temperature distribution in a radiant tube relatively flat. SOLUTION: A low-NOx radiant tube device is constituted in such a way that a communicative path 9 is formed between the exhaust side (b) and burner side (a) of a radiant tube 1, so as to suck a high-temperature exhaust gas from a burner 2 on the exhaust side (b) and return the exhaust gas to the burner side (a) through the path 9 by the kinetic energy of the exhaust gas. Since the exhaust gas is returned to the burner side, the longitudinal temperature distribution in the tube 1 can be made relatively flat.

摘要： PROBLEM TO BE SOLVED: To reduce the size of a burner by constituting a passage for supplying an oxidizing agent to the vicinity of a furnace side opening as a heat exchangeable tube and disposing the tube along the inner wall of the burner. SOLUTION: An outer wall 11 is arranged, at an interval, on the outer circumference of a burner body wall 10 extending from a heat storage section 3 to a furnace side opening 6 and the space between the walls 10, 11 is constituted as an oxidizing agent supply passage 8. The oxidizing agent supply passage 8 is constituted as a heat exchangeable tube made of ceramics or a heat resistant metal and an appropriate number of tubes are arranged along the inner wall of a regenerative burner 1. A section 9 for ejecting an oxidizing agent inward is provided at an end part of the oxidizing agent supply passage 8 in the vicinity of the furnace side opening 6. Since the distance from the oxidizing agent supply section 9 to a heat storage section 2 can be shortened, the burner 1 can be reduced in size.

摘要： PROBLEM TO BE SOLVED: To reduce the heat loss of a radiation heating type premixing burner and, to effectively burn organic matters contained in the exhaust gas of the burner by arranging an air-permeable porous material in the burning space of the burner and making the exhaust gas to pass through the porous material. SOLUTION: Surface combustion burners 12 are arranged inside a cylindrical main body 11 and an air-permeable porous material 13 is arranged in the inside space of the main body 11. An exhaust gas containing organic matters are sucked into the main body 11 through one opening of the main body 11 and the exhaust gas after burning is discharged from the other opening. In addition, dispersing plates 16 are interposed between the side wall of the main body 11 and burners 12 in a state where the plates 16 surround the burners 12 and a ceramic foam is applied to the porous material 13.

摘要： PROBLEM TO BE SOLVED: To simplify an apparatus and facilitate maintenance control by combusting a combustion product adjusting temperature to one where clinker is not produced, and performing heating fluidized particles with combusted gas, and further keeping an optimum the inside of a furnace by adjusting the amount of a fuel after furnace temperature reaches set temperature. SOLUTION: When heating upon starting is required, temperature of a combustion product is adjusted with an air ratio to a temperature where clinker is not produced and simultaneously combustion is performed with a burner 2 disposed at a lower part 3 of a furnace body, and with the combustion gas fluidized particles such as sand are flowed and simultaneously the fluid particles are heated. With the combustion, after the furnace temperature reaches set temperature, for example, 800 deg.C, a combustion amount is mainly adjusted to keep optimum a fluidized state in the furnace and states such as fluized bed layer temperature. Herein, the burner 2 is set in its injection speed at least to 10m/sec or more. Further, the burner 2 is formed into a tapered shape, and there are disposed a plurality of burners tangentially on the same plane of the furnace.

摘要： PROBLEM TO BE SOLVED: To solve a problem in a conventional constitution of a heat accumulating part in a regenerative burner having a structure wherein the intake air and the discharge air are approximately horizontally passed through in the heat accumulating part filled with a heat accumulator, that a clearance is formed at an upper side when a volume of the heat accumulator is reduced, and the combustion air and the discharged gas flow there, which causes impairing the heat recovering efficiency, and needs the supply of the heat accumulator. SOLUTION: The heat accumulating part 3 supported by breathable supports 2 at its both sides is formed in the lateral intake and discharge air channel 1, and the heat accumulator 6 is packed in the heat accumulating part. The breathable supports provide the mechanism for preventing impairing the heat recovering efficiency of the heat accumulating part in the regenerative burner wherein the ventilating part 9 is not formed at an upper side.
