PROBLEM TO BE SOLVED: To provide a heat storage part structure of a heat storage type burner that is easy to construct, can be manufactured in short time and at low cost, has a compact form, and can be installed with space-saving.SOLUTION: In a heat storage part structure of a heat storage type burner, a casing 4 that stores a spherical heat storage material 3 collecting heat from exhaust gas and heating combustion air with collected heat is provided in a gas passage 1 for a burner where combustion air and exhaust gas alternately circulate. In the casing, a central area CA where combustion air and exhaust gas circulate to a heat storage material is formed, and also, a projection wall 14 forming an outer peripheral area OA for preventing combustion air and exhaust gas from circulating to a heat storage material near to the side of an inner surface 9a of the casing is provided in such a manner as to surround the periphery of the central area. 【課題】施工が容易であって、短時間でかつ安価に製作することが可能であり、またコンパクトな形態であって省スペースで設置することが可能な蓄熱式バーナの蓄熱部構造を提供する。【解決手段】燃焼用空気と排ガスが交互に流通するバーナ用ガス通路１に、排ガスから熱を回収し、回収した熱で燃焼用空気を加熱する球状蓄熱材３を収容したケーシング４を設けた蓄熱式バーナの蓄熱部構造において、ケーシングに、蓄熱材に燃焼用空気や排ガスが流通する中央領域ＣＡを形成するとともに、中央領域の周囲を取り囲む配置で、ケーシングの内面９ａ側付近の蓄熱材に燃焼用空気や排ガスが流通するのを妨げる外周領域ＯＡを形成する突出壁１４を設ける。【選択図】図１
