摘要： PROBLEM TO BE SOLVED: To cool down the inside of a furnace in a short time by laminating a plurality of planar heat storage materials having a large number of through holes integrally while keeping a specified space such that the through holes of adjacent heat storage materials are not aligned each other and then sectioning the space between a heat storage body thus obtained and the inner surface of a radiant tube with a partitioning member. SOLUTION: A heat storage body 14a comprises a plurality of planar heat storage materials 15 of ring-like sintered ceramic, or the like, having a large number of through holes 16, and a plurality of spacers 17. The heat storage materials 15 and the spacers 17 are laminated alternately on the inner tube 12a of a burner such that the through holes 16 of adjacent heat storage materials 15 are not aligned each other before being fixed in an outer tube 13a. The space A between the outer tube 13a and a radiant tube is divided into two in the longitudinal direction by means of a baffle plate 23a. Exhaust openings 25a, 24a also serving as a cooling air supply opening and a combustion air supply opening, respectively, are made in front and rear of the baffle plate 23a.

摘要： PROBLEM TO BE SOLVED: To enable use of a heat-storage type burner as a heat source in a non-oxidizing or reducing atmospheric furnace and to increase energy saving effect by widening the use of the heat-storage type burner. SOLUTION: At least one pair of the heat-storage type burners 2a, 2b provided with the heat-storage bodies 3a, 3b are arranged in a furnace body 1, and when fuel is burned with one side of the heat-storage type burner, the combustion gas in the furnace from the other side of the heat-storage type burner is exhausted, and the fuel combustion and the combustion gas exhaust are alternately executed with both heat-storage type burners so as to heat the heat-storage body with the combustion gas and preheat the air for combustion. In the case of setting the air/fuel ratio at the time of burning the fuel with the heat-storage type burner to

摘要： PROBLEM TO BE SOLVED: To provide a burner device capable of shortening temperature raising time of a heat pipe heated by a burner flame, retaining a high temperature and preventing a jet in a liquid state. SOLUTION: A combustion nozzle device 2 comprises a nozzle holder 21 having an injection nozzle 22 protruding from an opening end of a passage connected to one end of a heat pipe 26, a mixing cylinder 24 fitted to an outer circumference of one tip end of the nozzle holder so as to make an air opening in a side part face the injection nozzle and a flame port nozzle 25 mounted on a tip end of the mixing cylinder, and is secured within a cover member 3 so as to be located with a specified distance from a tip end of the burner main body 1. The heat pipe disposed between the combustion nozzle device and the cover member is extended to a burner main body side on an axis same as that of the nozzle holder, and designed to be connected with a fuel passage via a connection cylinder member 27 formed within the tip end of the burner main body, and a heat insulated space is formed between the nozzle device and the burner main body.

摘要： PROBLEM TO BE SOLVED: To improve combustability of a fuel gas having a low heat generation rate by preheating fuel from a fuel supply source at the heat exchanging section of a heat storage section before being ejected from a fuel ejection section. SOLUTION: At a moment of time when a regenerative burner 1 operates on the combustion side, combustion air flowing through an inlet/outlet 5 is fed through the interconnecting passage of a support 4 into a heat storage section 2 where it is preheated with heat stored in a heat storage body 3 and supplied to the downstream side of the heat storage section 2 before being ejected from a fuel ejecting section 6 and mixed with fuel for combustion. Before being fed from a fuel supply source through a fuel piping 9 constituting a fuel passage to the fuel ejecting section 6, fuel is preheated with heat stored in the heat storage body 3 at the heat exchanging section 10 and ejected from the fuel ejecting section 6.
