Abstract  This article introduces two cooling methods of converter hood in copper smelter： atmospheric pressure vapor-cooled and circulating water-cooled， and explains the differences between the two methods. This article provides a detailed introduction to the design concept of a circulating water-cooled hood waste heat recovery system， including process flow， key control points， etc.， and analyzes the implemented engineering projects. The analysis shows that the circulating water-cooled hood waste heat recovery system has stable process， energy-saving and water-saving advantages， and good economic benefits， which is worth promoting.

Keywords  converter hood; vapor-cooled; atmospheric pressure vapor-cooled; circulating water-cooled; quantity of heat exchange; loop resistance
