Fluidized beds heated via fossil fuel combustion have been widely used for various applications, including mineral processing. Heating these fluidized beds with clean electricity is emerging as a promising solution to reduce greenhouse gas emissions and improve energy efficiency, operability, and product quality. Various heating principles can be applied for electrically heated fluidized beds (EHFBs), including Joule heating, induction heating, electromagnetic irradiation, sonication, plasma heating, and gas preheating. Graphite purification is described as an EHFB case study.
