IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...
