Automatic control method and system for ammonia water feeding of glass kiln

The invention relates to the technical field of ammonia water feeding of glass kilns, in particular to an automatic control method and system for ammonia water feeding of a glass kiln. According to the scheme, fire exchange signals on the left side and the right side of the glass kiln are collected, and the nitrogen oxide content at an inlet and an outlet is measured; and the ammonia water is fed in a timing and fixed-frequency feeding manner according to the fire change signal, or the ammonia water feeding target value on the corresponding side is corrected in an automatic tracking correction manner according to the content of nitrogen oxides at the inlet and the outlet, so that the final emission standard is achieved. According to the scheme, control over the feeding time and the feeding amount of the ammonia water is achieved by adopting different feeding modes, intelligent control over feeding of the ammonia water can be achieved, the accuracy and the feeding efficiency of control over the feeding time an
