Abstract

Anode baking is the most critical and expensive step in carbon anode manufacturing process. Therefore, more focus is required towards a safe baking process to achieve best product quality and optimized cost. The baking of anodes is a process where combustible substances are released. So there is high risk of fire and explosion in ring main duct of furnace and in fume treatment center. Modern baking furnaces are of open-type ring furnace with indirect heating of anodes in the absence of air. The risk associated at different stages of baking process and its consequences can be evaluated for the protection of operating personnel and furnace equipment. Such risk assessment study can be done for existing furnaces as well as new furnaces to be constructed. This paper will present and discuss the various causes of fire incident/explosion in furnace and how operational practices and safety systems can reduce the occurrence of fire incidents. Protection devices available in ABF at Aditya Aluminium (unit of Hindalco Industries Ltd.) and the existing operational practices to be carried out by ABF manager to minimize the losses are presented.
