The microprocessorbased system with the LSPE algorithm enabled the parameters to be obtained while the coalmill was operating online. The transfer functions obtained during these field tests allowed feedforward controllers to be designed that gave improved performance of the coalmill. The next section describes the coalmill operation.

May 15, 2016· Alarm threshold levels can be set to best suit the plant operating conditions. These settings can also compensate for externally introduced CO, where mills are using recycled combustion air for coal feed heating. The Millwatch probe is designed to withstand the erosive conditions at the mill outlet where the measurement is made.
