    • PROBLEM TO BE SOLVED: To provide a high temperature furnace in which even when temperature in an industrial furnace exceeds 1300 deg.C, the heat exchange of waste gas can be carried out and a thermal efficiency is improved by preheating air to a temperature in the range of 800 to 1000 deg.C. SOLUTION: The industrial furnace 1 comprises an exhaust gas exhaust system 3, a combustion air supply system 4 and N sets of passage switching heat storage type heat exchangers 10. When the temperature of combustion exhaust gas in the flue 5 of the exhaust gas exhaust system of the waste heat using device of the industrial furnace 1 exceeds 1300 deg.C, the opening degree of a cooling air quantity adjusting valve 19 of a cooling air supply system 15 is adjusted by an exhaust gas temperature control means 17 upon detection of the temperature of the exhaust gas by a detecting means 16 by an exhaust gas temperature control means 17 to suck air to be cooled, control the temperature of the exhaust gas to 1300 deg.C or lower and store heat in the heat storage element 12 of the heat storage type heat exchanger. The heat storage type heat exchanger is switched to change the passage from the exhaust gas exhaust system to the combustion air supply system. Then, the combustion air of the combustion air supply system is supplied to the industrial furnace as the preheated air in the range of 800 to 1000 deg.C by the heat exchanger.
    • 要解决的问题:为了提供一种高温炉,其中即使在工业炉中的温度超过1300℃的情况下,也可以进行废气的热交换,并且通过将空气预热至 范围800〜1000℃。 解决方案:工业炉1包括废气排放系统3,燃烧空气供应系统4和N组通道切换储热型热交换器10.当排气排气系统的烟道5中的燃烧废气的温度 在工业炉1的废热利用装置中超过1300℃时,冷却空气供给系统15的冷却空气量调节阀19的开度由废气温度控制单元17调节, 的废气通过排气温度控制装置17通过检测装置16吸入要冷却的空气,将废气的温度控制在1300摄氏度或更低,并将热量储存在蓄热元件12中的热量 储存式热交换器。 切换蓄热型热交换器,将从排气排气系统到燃烧空气供给系统的通路变更。 然后,通过热交换器将燃烧空气供给系统的燃烧空气作为预热的空气供给至工业炉,温度范围为800〜1000℃。

    • PROBLEM TO BE SOLVED: To provide a burner enabling stable combustion without the need for oxygen enrichment and heat in a heat treatment furnace up to a high temperature of 1800°C or higher.
      SOLUTION: A cap portion 5 having a fuel main blowout hole 51 and a fuel sub-blowout hole 52 is detachably mounted at an end 401 of a fuel pipe 4. During combustion with the burner 1, part of a fuel 101 passing through the fuel pipe 4 is blown out of the fuel sub-blowout hole 52 to a cooling passage 31, as a sub-blowout fuel 103, and mixed with cooling air 105 passing through the cooling passage 31 to form premixed gas 106. The premixed gas 106, a main blowout fuel 102 blown out of the fuel main blowout hole 51 and combustion air 104 blown out of an air blowout port 61 after passing through the air passage 21 are mixed together for combustion to generate heat in the heat treatment furnace 8.
