    • In a heat processing apparatus in which a gas/air mixture is piezoelectrically ignited to heat the combustion catalyst by the ignited flame for taking place subsequent flameless catalytic combustion of the gas mixture, a portion of the gas in the flaming combustion space is directly discharged to the outside not passing through the combustion catalyst upon flame ignition, while the entire amount of the gas in the combustion space is introduced to the combustion catalyst after reaching the catalytic combustion, by using a discharge gas control mechanism interlocked with the operation of the ignition button, as well as the opening degree of the external air ports is changed variably so as to provide suitable gas/air ratios upon ignition, flame extinguishment and usual catalytic combustion respectively by the air flow rate control member also interlocked with the ignition button.
    • 在其中气体/空气混合物被压电点燃以通过点燃火焰加热燃烧催化剂以进行燃气混合物的无焰催化燃烧的热处理装置中,将燃烧燃烧空间中的一部分气体直接排放到 在火焰点火时,外部不会通过燃烧催化剂,同时通过使用与点火按钮的操作联动的排放气体控制机构,在燃烧空间中的气体的总量被引入燃烧催化剂之后, 以及外部空气口的开度可变地改变,以便分别通过与点火按钮联锁的空气流量控制构件分别提供点燃时的合适气体/空气比,火焰熄灭和通常的催化燃烧。
