Title: O2 analytical type automatic oxidation and reduction burning device and method therefor
Inventor: NIIMI HARUO
IPC: F27B17/00
Filed: 1992-05-27
Abstract: PURPOSE:To simplify the analysis of an in-furnace O2 concentration by delaying the drive of a damper motor with a timer, assuming a delayed arrival of a comparison signal at the damper where there exists a time lag between an in-furnace O2 and an O2 value which has arrived at an O2 sensor at an O2 sensor for analysis. CONSTITUTION:Confirmation is made that there exists a time lag of about 60 seconds before an O2 sensor senses an O2 value of a kiln outputs its analyzed value and causes an adjustable timer 12 to intervene so that the drive of a damper motor 10 may be delayed for the time equivalent to the time lag. The delayed drive of the damper motor 10 synchronizes the output changes continuously produced by the analysis of the O2 sensor with the drive of the damper motor 10. This construction makes it possible to harmonize the in-furnace O2 concentration. It is also possible to harmonize the time lag at the arrival of the in-furnace O2 value at the O2 sensor by way of the timer.
