が提案されている。The partition wall of the furnace has a suspending structure in which it is suspended from the upper part, and the lower part of the partition wall usually has no support. For this reason, a method for suspending and supporting the partition wall is required, and various proposals have been made in the past. For example, Japanese Unexamined Patent Publication No. 4-187989 proposes a partition wall in which a support member is attached to an inorganic fiber block, the inorganic fiber block is attached to another support member, and the inorganic fiber block is vertically and horizontally connected. Also, the actual fair 6-23919
In the publication, a partition wall is proposed in which an inorganic fiber blanket having the same length as the height of the partition wall is supported only at the upper end portion.
