Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] In this embodiment, the main purpose is to find an optimized furnace pressure control method, which can keep the furnace pressure stable within a certain range under the frequent opening and closing of the furnace door and the disturbance of interference signals. The specific method is to fully analyze the interference factors that cause furnace pressure fluctuations in the furnace pressure control, find out the main interference factors, and implement control on the main interference factors, so as to eliminate the interference signals that cause furnace pressure fluctuations in the bud. , at the same time reduce the proportion of the furnace pressure fluctuation signal in the control, so that the flue gate action signal not only takes into account the fluctuation of the furnace pressure detection signal, but also takes into account the fluctuati...
