Abstract
The invention is directed to water-cooled furnace hoods that exhaust gases away from a work area, and in particular, it is directed to an off-gas hood for use with a basic oxygen furnace (BOF). The furnace hood includes an assemblage of panels fastened together to form a flue positioned above a BOF at a location to receive gases generated by the furnace. Each panel includes an inlet header for receiving cooling water, an outlet header for discharging cooling water, and a plurality of tubes, such as a tube-bar-tube membrane, extending between the inlet and outlet headers to distribute cooling water between the headers. Jumper pipes extend between outlet headers and inlet headers located in adjacent panels. The jumper pipes distribute cooling between adjacent panels and thereby provide a continuous flow of cooling water along the length of the flue. The invention is also directed to a method of replacing the panels located in the assemblage of panels that make up the flue.
