AI Technical Summary
During the combustion process of ceramic kilns, the air-fuel ratio adjustment is delayed, causing the furnace atmosphere to fluctuate frequently between oxidation and reduction, which affects the color stability of ceramic glaze and the firing quality of the body. Existing compensation methods cannot adapt to real-time changes.
By performing phase analysis on the two signals of furnace pressure and flue gas oxygen content, the response lag time of air-fuel ratio adjustment is extracted, and phase compensation technology is used to correct the basic adjustment amount on the time axis, so as to achieve precise dynamic adjustment of air-fuel ratio.
It eliminates the timing misalignment caused by combustion lag, improves the accuracy and stability of air-fuel ratio regulation, and enhances the firing quality of ceramic products.
