Case Analysis of Steam Lithium Bromide Refrigeration Applied to the BOF Central Control Building
The gas channel for vaporization cooling is used to recover waste heat from the primary gas of the BOF,which generates a large a-mount of steam.The most ideal application location for this steam is the BOF plant.Taking the steam lithium bromide refrigeration system of a certain BOF central control building as an example,this article mainly introduces the cooling load distribution of the central control building,the design of the refrigeration system,and relevant guarantee and auxiliary measures.It also compares electric refrigeration with steam lithium bromide refrigeration.For the central control building matched with two set of BOF,the summer cooling load is about 260kW and the steam consumption of steam lithium bromide refrigeration is about 290 kg/h.The refrigeration station is located near the central control building and adopts a constant flow water system.The refrigeration unit does not need to be considered as a backup.When the refrigeration unit malfunc-tions and needs maintenance,mechanical ventilation can be temporarily used to remove residual heat from the electrical room.Compared with electric refrigeration,the energy-saving effect of steam lithium bromide refrigeration is very obvious,and the initial investment can be recov-ered within one year.
