Presentation Title 25 Years of Naural Gas Purged Infrared Pyrometer Temperature Measurement For The Operation Of Open-Top Anodes Baking Furnaces
Author(s) Yvon Menard
On-Site Speaker (Planned) Yvon Menard
Abstract Scope To improve a low flue walls life, a natural gas purged infrared pyrometer system was implemented to replace original thermocouples based temperature measurement system on firing system, in 1991. Flue wall life increased to be over 100 cycles, on Pechiney furnaces, by preventing flue walls overheating. Anodes baking quality is adequate for two burners ramps fire technology. Some problems had to be corrected over time as they appeared: calibration drift, pinched injector tubes, frosted pyrometers lenses, etc. Pyrometers and thermocouples measurement technologies can both successfully bake anodes to specifications, but original cost, ease of operation, ease of maintenance and effect on refractory may favor one system over the other, depending on plant situation.
