Abstract:

Direct Flame Impingement (DFI) involves the use of very high-velocity flame jets impinging on a work piece to rapidly heat the work piece. The predominant mode of heat transfer is convection. Because of the locally high rate of heat transfer at the surface of the work piece, the refractory walls and exhaust gases of a DFI furnace are significantly cooler than in conventional radiant heating furnaces, resulting in high thermal efficiency and low NO x emissions. A DFI furnace is composed of a successive arrangement of heating modules through or by which the work piece is conveyed, and can be configured for square, round, and flat metal shapes (e.g., billets, tubes, and flat bars) in single- or multi-stranded applications. This paper presents the results of CFD modeling of the DPI process and the results of physical tests with simulated and actual metal loads in a laboratory-scale DPI furnace.
