Abstract Scope |
Gas fired furnaces are responsible for most of the scope 1 emissions of secondary aluminum production. In the context of decarbonization of aluminum cast houses, air gas fired furnace retrofit solutions being compared are oxy burners, hydrogen combustion and electric plasma torches. However, many questions remain on the performances of these technologies and their impact on emissions and metal quality.
This paper presents the results of an experimental campaign on a furnace equipped with a 47 kW oxyfuel burner able to run with natural gas, hydrogen or a mix of both. The aim of this study is to validate previous simulation models for the melt rate and the energy consumption that indicated oxy-hydrogen as a good retrofit solution, to study the impact on the dross rate and magnesium loss for a 5000 series alloy and to prove the feasibility of the concept. |
