Effect of Combustion Air Preheat on a Forged Furnace Productivity
Abstract
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. What this analysis is not able to determine are the effects of combustion air preheat on four additional furnace operating characteristics. These characteristics are: (1) fuel utilization of a furnace operating cycle; (2) time to heat the furnace load; (3) scale production; and (4) furnace uniformity.
The capabilities to perform the above comparative analysis now exist within a single facility. In this facility, Solar Turbines Incorporated, under contract to the Gas Research Institute, has recently installed a newly developed high temperature metallic recuperator in a new fiber-lined furnace.
This paper summarizes some preliminary test results of instrumented billets in selected gas fired furnaces.
