    • A small microcombustion heater which can realize reliable combustion. The heater has a premixed gas passage which reaches a combustion chamber, and a passage for a combustion gas drawn from the combustion chamber. The passages are arranged in a spiral form in a manner such that a heating wall is provided between the passages. The width of the premixed gas passage is a quenching distance or less, where the quenching distance is determined depending on the premixed gas. The heater has two outer faces for holding the spiral passages from both sides of the upper and lower edges of the heating wall, and at least one of the outer faces is a heating surface for emitting radiant heat. Typically, the spiral passages are placed between a heat-resisting heating plate and a heat insulating plate, and an outer face of the heat-resisting heating plate functions as the heating surface.
    • 可实现可靠燃烧的小型微型燃烧加热器。 加热器具有到达燃烧室的预混合气体通道和从燃烧室抽出的燃烧气体的通道。 通道以螺旋形式布置成使得在通道之间设置加热壁。 预混气体通道的宽度为淬火距离以下,其中淬火距离取决于预混合气体。 加热器具有两个外表面,用于从加热壁的上边缘和下边缘的两侧保持螺旋通道,并且至少一个外表面是用于发射辐射热的加热表面。 通常,螺旋通道被放置在耐热加热板和绝热板之间,并且耐热加热板的外表面用作加热表面。
