Abstract
A method for regulating or controlling the content of NO,in the exhaust gases of a glass-melting furnace having several burners operated in alternation, wherein both the beginning and the end of a combustion break (FP,, FP,) are supplied to a binary signal generator (,) which passes a signal to a regulator (,) with a time delay and upon receipt of the time-regulator (,), and the amount of NH,supplied to the denitrating plant is adjusted to a lower constant fixed value F,via a control, and by means of a memory element (,) a higher constant fixed value F,is calculated as amount of NH,and supplied to the regulator (,), whereupon as soon as the regulator (,) has received the signal of the time-delayed end of a combustion break, the fixed value F,is adjusted to the fixed value F,via a control, and subsequently the regulation is directly continued.
