Abstract
Przedmiotem wynalazku jest sposób wykrywania i sygnalizowania zakłóceń w pracy młyna węglowego średniobieżnego, zwłaszcza zakłóceń powstających w wyniku zawieszania się węgla w zasobnikach przykotłowych podczas przygotowywania pyłu węglowego przeznaczonego do spalania w kotle energetycznym. Sposób charakteryzuje się tym, że sygnał proporcjonalny do mocy silnika młyna i sygnał wysterowania podajnika podaje się do modelu adaptacyjnego (MA), gdzie w oparciu o te sygnały tworzy się sygnał zamodelowanego bieżącego punktu pracy układu młyn -podajnik, od którego wartości tworzy się sygnał logiczny wykrycia braku węgla. W utworzonym sygnale zamodelowanego bieżącego punktu pracy układu młyn - podajnik uwzględnia się zmienność mocy młyna w zależności od stanu jego wyeksploatowania, przesterowanie podajnika węgla oraz wzajemne aktualne współzależności między tymi wielkościami, zaś zadaną wartość sygnału logicznego wykrycia braku węgla uzależnia się od wysterowania podajnika.The subject of the invention is a method for detecting and signaling disturbances in the operation of a medium speed coal mill, especially disturbances arising as a result of coal hanging in the boiler tanks during the preparation of coal dust intended for combustion in a power boiler. The method is characterized in that the signal proportional to the mill motor power and the feeder control signal is given to the adaptive model (MA), where based on these signals a signal of the modeled current operating point of the mill-feeder system is created, from which values a logical signal is created detection of carbon shortage. The created signal of the modeled current operating point of the mill - feeder system takes into account the variability of mill power depending on its state of exploitation, overloading of the coal feeder and mutual current correlations between these quantities, while the set value of the logical signal for detecting lack of coal depends on the control of the feeder.
