◎ ACS system can realize intelligent operation under the automatic operation state, and the intelligent operation rate is 97.9% except individual abnormal situations that require artificial intervention during operation;

◎ According to the number of times of regulation during manual operation and the number of times of regulation through artificial intervention during ACS automatic operation, the coal feeder of the control mechanism can decrease the operation frequency of operators by 71.8%, and the secondary fan of the control mechanism can decrease the operation frequency of operators by 72.2%;

◎ Through comparison of the boiler load (MW) under the automatic mode and the manual mode, a conclusion is drawn that the boiler load as the main control object under the automatic operation state is stable, and the parameter control object can be controlled within the required value.
