Claims

[Scope of utility model registration request]

A part of the central wall tube of the boiler is bent approximately horizontally at the ceiling to form a ceiling wall, and the remaining central wall tube is bent approximately horizontally above the ceiling, and a hanging lug is attached to the bent portion. In the case where the hanging lug is fixed to support the central wall load, at least the bent part of the remaining central wall pipe and the vertical part connected to the bent part are arranged so that the hanging lug is disposed outside the ceiling wall seal fin. A boiler characterized in that a portion is formed so as to be located above the ceiling seal fin.
