Feasibility analysis of steam waste heat of a steel mill for cooling in summer

Presents the principle of single-effect LiBr absorption refrigerating machines, and makes thermal calculation based on daily steam discharge rate in a certain steel mill. The result shows that the LiBr absorption refrigerating machine using steam waste heat as the heat source has a significant energy saving and emission reduction effect compared with other cooling methods, and also has better economical efficiency. This method is worthy to apply in area with rich waste heat resources.
