连续加热炉（200）包括炉主体（212），输送单元（210），其被配置为输送炉主体中的焙烤物体W，多个由燃烧加热的加热部分，每个具有第一辐射表面 （120a），其被配置为通过燃烧加热并将热量传递到由所述输送单元输送并沿所述烘烤对象在所述炉主体中的输送方向上布置的烘焙对象;以及冷却预热器（214），其具有第二辐射表面 214a），其被配置为当与由所述输送单元输送的烘焙对象相对的时候从所述烘焙对象接收辐射热;以及气体流路，被配置为通过来自所述第二辐射表面的热预热所述加热部中用于燃烧的气体。 根据连续加热炉，当进行相对于烘烤对象的加热和冷却时，可以提供足够的冷却性能和高的热效率。

And a continuous heating 200 furnace body 212, is heated by the transfer section 210 for transferring the accused Dangerous (W) in the furnace body, the combustion, heat transfer by radiation to the accused holy that is conveyed from the conveying unit claim 1 has a copying surface (120a), and when in the juxtaposed in the conveying direction of the accused Dangerous plurality heating element in the furnace body, is opposed to the accused holy that is conveyed in the transport section, and the second copy to receive radiant heat from the accused Dangerous to surface (214a), and a second cooling preheating unit 214 having a gas flow path to preheat the gas to be used for combustion in the heating element due to the heat from the radiant surface. According to this continuous heating, in doing the heating and cooling, it is possible to achieve both good cooling performance and high thermal efficiency for the accused holy.
