Effects of Combustion Air Preheat on a Forge Furnace Efficiency

摘要

A basic thermal analysis of a gas fired forge furnace can determine the fuel savings from exhaust energy recovery/combustion air preheat on a furnace operating at a single condition, for example, high fire. The capabilities to perform the above comparative analysis now exist within a single facility. In the facility, Solar Turbines Incorporated, has recently installed a newly developed, high temperature metallic recuperator in a new fiber-lined furnace. The report summarizes some preliminary test results of instrumented billets in selected gas fired furnaces.
