Abstract
The iron and steel industry produces a large number of low-grade waste heat resources, which are not fully utilized. In addition, the iron and steel
industry consumes a lot of water. This paper presents a method of utilizing waste heat of blast furnace slag flushing water for seawater desalination.
After the flash process, heat exchange process and heat repair process, the blast furnace slag water was converted into steam which is 70 °C, which
provided a heat source for MED (Multi-effect Desalination). This utilization method of waste heat was verified by thermodynamics and production
data.
