摘要： PROBLEM TO BE SOLVED: To enable the flame spray repairing of damaged carbonizing chamber wall quickly even when the place of the damage is near the longitudinal center of a furnace body by a method wherein a board pushing device, pushing a ceramic fiber board, inserted into a combustion chamber through the inspection port of the same to prevent the blow-out of flame, against the penetrating damaged part, is provided. SOLUTION: A board pushing device 8 is set in a combustion chamber through an inspection port to push a board type body against a penetrating damaged part so that ceramic flame spray material, sprayed from a carbonizing chamber, will not be blown out into the combustion chamber. The ceramic fiber board or a carbon based board is employed for the board type body. The board pushing device 8 blocks the penetrating damaged part through the board type body 9, hang at the tip end of a board pushing arm 14, by turning an arm driving handle 16 to slant a board pushing arm 14 toward the direction of the penetrating damaged part by a warm gear 12 and a rack 13 through an arm driving shaft 17.

摘要： PROBLEM TO BE SOLVED: To quicken the repairing of a carbonizing chamber wall damaged to generate a through hole, even when the position of the damage is near the longitudinal center of an oven by a method wherein a ceramic fiber board is pushed from the side of a combustion chamber against the penetrated damaged part, generated on the carbonizing chamber wall, partitioning the carbonizing chamber of a coke oven from a combustion chamber of the same, to block the through hole. SOLUTION: In a coke oven, coal is charged from a furnace top coal charging port 5 into a carbonizing chamber 11, then, the carbonizing chamber wall 6 is heated by the conduction of heat from a combustion chamber 10 to distillate the coal in the carbonizing chamber 11. When coke cake, produced after distillation, is hooked by amorphous deposit carbon and the like, bricks, constituting the carbonizing chamber wall 6, are fallen away and a penetrated damage is produced. In this case, ceramic flame spray material is sprayed from the inside of the carbonizing chamber 11, however, a ceramic fiber board 9 is pushed from the inside of the combustion chamber 10 by a board pushing device 8 to block the penetrated damaged part 1. In this case, the damage can be repaired by using a carbon board instead of the ceramic fiber board 9.

摘要： PURPOSE:To prevent the leakage hazard from a tube caused by oxidative corrosion, and to recover the exhaust heat from a high-temperature zone very efficiently, by using a ceramic tube as an outer tube, in a heat exchanger of double tube-type, provided to a heating furnace or the like in order to preheat the air. CONSTITUTION:The air is fed into an inner tube 4 from an air feed header 4, falling down through the inner tube 4, and let it out of the inner tube 4 from an outlet 5 into a gap 7. After that, the air is turned round to go upward in the neighborhood of a ceramic block 10, and on its way, it is preheated by the heat from exhaust gas which contacts with the outer surface of a ceramic outer tube 6, and is raised up into a highly heated gas header 2. By using a ceramic tube for the outer tube 6, the tube is prevented from leakage caused by oxidative corrosion, and exhaust heat from a high-temperatured zone can be recovered. When ceramics of the outer tube 6 is expanded at the time of exchanging heat, the outer tube 6 is extended to the side of a hole 17 on the wall 12 of a lower duct, and its extension is absorbed by the spring of a supporter 8. With such an arrangement, the ceramic tube is prevented from being damaged or from leakage.
