These Metal7 patented technologies bring benefits in terms of plant throughput increase and improvements in furnace permeability, thus reducing energy consumption. They both create a segregated bed profile in the furnace. In other words, the larger pellets are placed on top of the smaller pellets. When warm air flows downward, it concentrates intense heat on the larger pellets, which require more thermal energy to be fired. The residual heat then takes care of the smaller pellets, which require less energy. This approach optimizes energy use. Additionally, our Epsilon chute maintains the pellets' sphericity, enhancing airflow through the pellet bed profile, and improving overall firing efficiency, resulting in added reduced energy consumption.
