摘要： PURPOSE:To improve high temperature strength, by a method wherein a double cylinder, disposed in a heating furnace, is formed by silicone nitride ceramic. CONSTITUTION:In an outer cylinder 3 and an inner cylinder 4 of a single end type radiant tube burner 2 are formed by silicone nitride ceramic. Bending strength is increased about 2 times as high as that of a cylinder formed by silicon carbide ceramic, and the coefficient of thermal expansion is about 0.75 of that of a cylinder formed by silicone carbide ceramic. Thereby, deformation due to external stress or under its own weight and thermal deformation can be reduced, and when the outer cylinder 5 is disposed in a condition that both ends are secured, durability can be improved. Further, since thermal conductivity is increases about 1.8 time as high as that of a product formed by silicon carbide ceramic, temperature distribution of the outer cylinder 3 can be uniformized. A combustion heat is radiated from the outer cylinder 3 to the outside, and this enables improvement of thermal efficiency prevailing during heating of an object to be heated in a heating furnace 1.

摘要： PURPOSE:To reduce NOX by installing a flame retention type premixing burner as an annex by way of a burner port board and supplying enriched mixed fuel to the premixed burner and the flame port board on one side and thin mixed fuel gas to the other side in a small burner for household service or the like. CONSTITUTION:Enriched mixed fuel gas is supplied to a premixing burner 1 while thin mixed fuel gas is supplied to a flame port board 7, thereby carrying out combustion. Then, the enriched mixed fuel gas present above the premixing burner 1 is burnt with the air as a secondary air which is supplied from an air flow passage 10 with an excess air prevailing above the flame port board 7. It is, therefore, possible to prevent the generation of incomplete combustion in the combustion of enriched mixed fuel gas. In this case, the air ratio of the combustion enriched mixed fuel gas is specified as about 0.4% while the air ratio of the mixed thin fuel gas is set so as to range from about 1.2 to 1.5. In this manner, when enriched or thin combustion is carried out, there will no need to supply the secondary air while the need for the air flow passage 10 will be eliminated as well.

摘要： PURPOSE:To eliminate the need of providing means such as an electric heater and the like in a water tank by installing the water tank having a water supply section just above a hot-water storage tank, connecting the hot-water storage tank and the water tank through a heat/water supply tube, and providing a heating section in the hot-water storage tank. CONSTITUTION:Water supplied from a water supply section 2 to a water tank 3 is naturally supplied from a heat/water supply tube 4 into a hot-water storage tank 1. The water in the hot-water storage tank 1 is circulated by a pump 7 through and heated by a heating section 5 comprising a burner 8 and heat exchanger 9 and the like. Hot-water in the hot water storage tank 1 is supplied from a hot-water supply section 10. Thereupon, since the hot-water storage tank 1 and the water tank 3 are connected through the heat/water supply tube 4 an the water tank 3 is installed just above the hot-water storage tank 1, heat of the hot-water storage tank 1 can be transmitted to the water in the water tank 3 through the heat/water supply tube 4 and simultaneously the water tank 3 can be heated only with heat radiation from the hot-water storage tank 1 itself. Thus, the water in the water tank 3 can be prevented from being frozen. Further, since the water tank 3 is constructed integrally with the hot-water storage tank 1, there is unnecessary a particular installation place for the water tank 3.

摘要： PURPOSE:To lower the exhaust temperature of an exhaust gas to or below the saturation temperature of the gas and enable effective recovery of the latent heat of evaporation, by partitioning the interior of a water-heating tank into upper and lower water-heating parts, providing a second indirect hot-water heat exchanging part on the downstream side of a first indirect hot-water heat exchanging part in a hot water circulating system provided for the upper water-heating part, and connecting a return pipe between the downstream side of the second heat exchanging part and a lower part of the lower water-heating part. CONSTITUTION:A combustion exhaust gas generated at a burner 14 is discharged from a combustion chamber 5 through an exhaust pipe 7 and an exhaust chamber 6, while making heat exchange with water contained in a water-heating tank 1 to heat the water in a water- heating part 3 to a higher temperature, as compared with the water in a water-heating part 4. The water heated in the water-heating part 3 is passed through an indirect hot-water heat exchanging part 8, when it is cooled through heat exchange with the water in a hot water supplying system C. The hot water reaching the downstream side of the heat exchanging part 8 while being lowered in temperature is divided into a portion fed toward a lower part of the water-heating part 3 and a portion fed toward an indirect hot-water heat exchanging part 9. The hot water reaching the lower part of the water-heating part 3 is again heated. The hot water fed toward the heat exchanging part 9 is further lowered in temperature through heat exchange with the water on upstream parts of the system C, is then returned from the downstream side of the heat exchanging part 9 to a lower part of the water-heating part 4 through a return pipe 10, and is re-heated.

摘要： PURPOSE:To promote a radiation thermal conducting action for a first thermal conducting pipe and a convection thermal conduction for a second thermal conducting pipe so as to improve an efficiency of thermal conduction by a method wherein the first thermal conducting pipe, a plate-like radiation body having through holes therein and the second thermal conducting pipe are arranged in this order from an upstream side and then a rate of opening of the radiation body is specified. CONSTITUTION:A plate-like radiation 27 having through holes with a rate of opening of 10-50% is laterally arranged between a first thermal conducting pipe 23 and a second thermal conducting pipe 25. Practically, a circumferential edge of the radiator 27 is mounted on stays 28 fixed to inner walls of a casing 20. A nominal diameter of each of the through holes is assumed to be 5-30mm. If the nominal diameter is more than 5 mm, a reaching distance of injection flow of hot gas discharged from the through holes is long and the gas sufficiently reaches up to a piping region of the second thermal conducting pipe. It the nominal diameter is less than 30mm, in particular, less than 15mm, it is possible to arrange the through holes substantially in uniform manner over a plate surface of the radiation body. A non- organic fibrous molded body is most preferably applied as the radiation body 27. The non- organic fibrous molded body has a resiliency and since it is endurable against a thermal shock received by the radiation body 27.
