Ceramic Heat Recuperators for Industrial Heat Recovery. Final Report

摘要

Development of a GTE ceramic recuperator, designed for relatively small furnaces with firing rates of 0.3 to 0.6 MM Btu/h and with exhaust gas temperatures of 1500 to 2600 F, is described. The ceramic selected as the material of construction is cordierite, a magnesium aluminum silicate. Details of the ceramic recuperator design are presented in Chapter 2. Also results of tests and measurements, system economics, and cost performance analyses are presented. Five demonstration programs were performed to determine the heat transfer performance of the recuperator, establish the energy savings by recuperation, demonstrate minimum maintenance requirements in typical furnace operation, determine the durability of the ceramic core, determine the operating requirements of the burners and controls with recuperation, and establish the overall system costs and payback period. Demonstration programs and results of the Bliss Mill Furnace, Tungsten Reduction Furnace, Glass Tank, Pilot Plant US Smelting Furnace, and Rotary Calciner Furnace are given in Chapter 3. Chapter 4 develops the methodology and shows how an impact analysis may be performed. Industrial applications are implied and a process flow diagram for smelting and refining primary copper is shown. Concluding chapters present conclusions and recommendations, a bibliography, and additional information in appendices. (ERA citation 06:012474)
