Research on the Co-processing of Mixed Electrolytic Aluminum Waste in Circulating Fluidized Bed Boiler Lei Shi, Zhiming Jiang, Yunquan Li, Ruiyu Li, Zhengrong Zhu, Shixin Zhang, Lei Deng*


In this study, a mixed combustion system in a fixed bed is proposed to deal with electrolytic aluminum waste. The feasibility of the laboratory-scale fixed bed burner system is verified. The effect of different mixing proportions, temperatures (i.e. 900, 980 and 1050 °C) and the addition of limestone on the products of combustion and pollutant emission is investigated through SEM and XRD analysis. The results show that the combustion process and the physical characteristics of the product are exhibited by mixing with 7:3 (coal: waste) ratio at 900 °C. Adding limestone meets the requirements of using circulating fluidized bed boilers for mixed burning of electrolytic aluminum waste. This study provides a theoretical basis for commercialization.
