温雰囲気に曝され、表面が溶融して、壁面がクリ
ンカとして付着するためである。 In a garbage incinerator or the like, depending on the incineration conditions, a large amount of clinker (welded ash) may adhere to the furnace wall. This is because the combustion residue is exposed to a high temperature atmosphere while flying through the furnace, and the surface melts and adheres to the walls as clinker.
一方、炉壁は本来自立構造であるが、このクリ

である。Means for Solving the Problems To achieve this objective, the present invention proposes that the tip of an anchor attached to the outer shell of the furnace be inserted into a cavity formed in one end of a pair of horizontally juxtaposed insulating bricks. At the same time, two other insulating bricks are arranged adjacent to the upper and lower surfaces of one end side portion of the pair of insulating bricks, in which the cavity is open, to cover the tip of the anchor, and having the cavity. Five refractory bricks constituting the inner surface of the furnace are arranged adjacent to the end face, upper, lower, left, and right sides of the other end of the pair of insulating bricks, and the upper and lower surfaces of the other end of the pair of insulating bricks having cavities are arranged. A heat-resistant member is inserted into a cavity defined by a groove formed to face the lower surface of the upper refractory brick facing the upper and lower surfaces of the upper refractory brick, and the upper surface of the lower refractory brick to connect these bricks. Grooves are formed facing each other on the lower surface of the upper refractory brick, the upper surface of the lower refractory brick, and the upper and lower surfaces of the refractory brick located adjacent to the end surface of the other end portion of the pair of insulating bricks having the cavity. Another heat-resistant member is fitted into the cavity defined by the bricks to connect these bricks.
