Inconsistency between the FRNC-5 excess air coefficient and oxygen content control
Thread Content
I would like to ask a question about FRNC-5. The peroxide level in tubular heating furnaces is usually set at 110%, yet the oxygen content in the flue gas as calculated during operation is less than 2%, which contradicts the fact that oxygen analyzers regulate the oxygen level to be between 2% and 4%. I don’t know how this situation is usually handled
The excess of 110 is intended to achieve complete combustion; the calculated value of 2% represents the oxygen remaining after burning is complete. The zirconia value is just an operating range. You need to be able to operate it on-site. It is recommended to check out tubular heating furnaces by Qian Jialin.
