This paper proposes a method for high-efficiency utilization of high-temperature molten steel slag with three stages and three media, introducing the technical route and equipment as well. The heat recovery efficiency and exergy efficiency are obtained through the calculation of mass balance and energy balance.
When the waste heat stored in steel slag is used for cogeneration, the theoretical heat recovery rate can reach 83.98 pct, and the exergy efficiency of the overall system is 38 pct. The normal-temperature solid steel slag produced by the process is easy for iron selection and subsequent high value-added utilization.
The molten steel slag is fully cooled through three-stage heat exchange, and the heat in it is fully recovered. This paper introduces the basic principles of the process route and the equipment. The heat recovery efficiency and exergy efficiency are also calculated through mass balance and energy balance.
When the waste heat stored in the steel slag is converted for electric energy, the theoretical heat recovery rate can reach 24.49 pct, and the exergy efficiency of the overall system is 33.83 pct.
The solidification of steel slag in this process consumes a large amount of CO 2 so that the free calcium oxide (f-CaO) in the steel slag is fixed, which is more conducive to subsequent utilization, thereby achieving the purpose of energy saving and emission reduction.
