Abstract
In the present invention, many cooling pipes are arranged horizontally at least in any one of the walls or roof of a furnace, to be fitted at the respective ends on both sides with supporting pipes provided outside the furnace, to let the cooling medium flow in one system for high cooling efficiency and long life. The cooling pipes may be arranged in ladder fashion or in a similar way, to keep the splash film stable, thereby preventing the decrease of the thermal efficiency of the furnace.
