Three-Stage Method Energy–Mass Coupling High-Efficiency Utilization Process of High-Temperature Molten Steel Slag

ABSTRACT: High-temperature molten steel slag is a large amount of industrial solid waste containing available heat energy and resources. This paper introduces an efficient and comprehensive utilization process of high-temperature molten steel slag. The waste heat energy in the high-temperature molten steel slag can be fully recovered through the three-stage heat exchange. Through mass balance and energy balance, the theoretical heat recovery rate can reach 81.42 pct when the waste heat stored in steel slag is converted into usable heat energy, and the exergy efficiency of the overall system is 27.93 pct. 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. W
