Intermediate- and High-Temperature Flue-Gas Recuperators for a Variety of Industrial-Process Environments. Project 61006 Final Report

摘要

An industrial recuperator design that uses reradiant heat transfer to achieve improved recovery efficiency was field-evaluated. Modifications were made to an aluminum remelting furnace. Average fuel savings for the recuperated mode was 31%. The internal rate of return for the cash flows calculated for the recuperators with and without the reradiant insert were, respectively, 46.0% and 41.6%. (ERA citation 07:061720)
