Traditional waste heat recovery (WHR) in the cement industry [31,32] typically employs the steam Rankine cycle and ORC. However, the efficiency of industrial waste heat utilization in the cement industry is limited and often suboptimal, and very few studies have combined cement waste heat utilization with the LAES system.
