The figure to the right shows a three dimensional plot of a thermal analysis performed by Wellman engineers using a sophisticated finite element analysis (FEA) computer modeling program.  It indicates the temperature gradients in the refractory walls of a slag collection sump which are heated by three sets of electric elements.  This study allowed Wellman to advise our customer how to maximize the electric heat input to this system without overheating the refractory or the heating element materials.

The figure to the left is a time-temperature chart generated from a heat transfer model developed by Wellman to calculate the time required to heat ceramic particles by convection on a belt conveyor.  The individual curves are for each .125” layer in the bed from top to bottom.  The red curve on the right shows the heating rate of the belt itself.
