High-temperature burner-duct-recuperator (HTBDR) system low-pressure seal development: Final report

Technical Report ·
OSTI ID:6233559

Development has been completed of a ceramic recuperator and its companion high-temperature preheated combustion air burner. The system is designed to operate in a variety of industrial flue gas streams with exhaust temperatures up to 2500/sup 0/F. The ceramic recuperator provides combustion air preheated up to 2000/sup 0/F to the high-temperature burner. Development of low-pressure seals to join the ceramic recuperator components was performed as an integral part of the program. While operating at high temperatures, the recuperator requires seals effective in minimixing both leakage and stress concentrations in the joints between ceramic components. Seal design, composition, leakage performance, and seal characterization were evaluated for cement, glass, and fiber packing seals. Laboratory studies have demonstrated that effective, low-leakage seals were developed and incorporated into the HTBDR industrial design.
