Lazar continuous carbon baking – the Future is now

Nicholas Walla, Steven J Dubec, Rick Lazarou

Abstract


The Lazar Continuous Carbon Baking Furnace (CCBF) presents a groundbreaking new process for the baking of carbon anodes.  A static thermal profile provides a consistent heat-up rate across distinct temperature zones, eliminating thermal cycling. Complete PAH destruction, combined with the lack of thermal cycling, eliminates refractory maintenance requirements and allows for tighter tolerances in pollution-control systems, leading to a significant decrease in operating costs. Costs to build a Lazar CCBF are estimated to be 35 to 45% less than conventional ring-type furnaces, with operating costs estimated to be approximately 60% less.
