Modelling centrifugal-granulation-assisted thermal energy recovery from molten slag at high temperatures
It remains a longstanding challenge to recover the waste heat from molten slags in pursuit of lower energy and carbon intensity in the metallurgical industry. To tap the heat from molten slag, the enabling technology i.e. centrifugal-granulation-assisted thermal energy recovery (CGATER) has been proposed and evolved from the laboratory concept into technological embodiment. Further development and deployment of CGATER necessitate a thorough, informative understanding of the multiscale CGATER physics; this is often enabled by modelling. Yet, the availability of informative CGATER physics is very limited due to the insufficiency and complexity of CGATER models. It is thus nontrivial to understand the current CGATER models and most importantly, the challenges and opportunities in future CGATER development. Herein, we first introduce the fundamental physics of CGATER. Second, we provide an overview of the CGATER models in the recent decade. Finally, we further analyze the missing pieces in current CGATER models and suggest future development of the CGATER models. According to the authors’ opinion, revisiting current CGATER models is essential. In the future, joint efforts from academia and industry are advocated to develop multiscale, multiphase CGATER models which are expected to accelerate the large-scale implementation of CGATER in the metallurgical industry.
期刊介绍:
The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change.
Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
