COMBINATION LEFT AND RIGHT HANDED FURNACE ROOF Abstract of the Disclosure A combination left- and right-handed roof system adapted for use in electric arc or other furnaces having roof removal in either a clockwise or counterclockwise direction. The roof system is spray cooled by a coolant and includes a coolant drain system divided into at least two segments and having opposing inlets for receiving spent coolant. Two pairs of adjacent coolant outlets are provided for connection with a coolant collection pump, depending upon the direction of roof removal, and each outlet in each of the pairs is associated with a different drain system segment. A removable U-shaped conduit connects the two outlets of the pair disconnected from the coolant collection pump. Coolant may flow from one inlet, directly through a single drain system segment, and be removed from the roof through one of the connected outlets. Coolant may independently flow from the opposite inlet, through the U-shaped conduit and another drain segment, and be removed from the roof through the other connected outlet.
