Abstract
The purpose of the present invention is to provide a furnace wall in which a throat section with a smaller channel diameter than other regions can be formed using all peripheral wall tubes. Provided is a furnace wall comprising: a plurality of peripheral wall tubes (), which are disposed so as to form a cylindrical shape when aligned in one direction and through the interior of which cooling water flows; and fins () that connect neighboring peripheral wall tubes () in an airtight manner. In a throat section in which the diameter of a horizontal cross-section of the cylindrical shape is reduced in comparison to other regions, the peripheral wall tubes () are disposed so as to be in mutual contact and the fins () are disposed on the inner circumferential sides of the cylindrical shapes.
