Increased Efficiency through Waste Heat
... Direct heat recovery to the product. This is the most efficient method. It takes advantage of the fact that even in the highest temperature processes, the product or charge enters the process at ambient temperature. If exhaust gases leaving the high temperature portion of the process can be brought ...
