High Temperature Burner-Duct-Recuperator System Evaluation: Second Annual Report, October 1982--September 1983

摘要

Activities in the second year of a project to develop a high-temperature burner-duct-recuperator are reported. The recuperator is designed to operate in high temperature flue gas streams that contain contaminants and delivers 2000 F preheat air to the combustion system of a steel mill soaking pit. A prototype recuperator was constructed and evaluated. Analysis thermal and fluid flow, flow induced vibration, stress, and materials test data were obtained. Final recuperator system design modifications were made, based on the prototype results, and system fabrication was initiated. Other activities included the development of a high temperature burner, completion of a preliminary economic analysis, and host site preparation. (ERA citation 13:046743)
