Get PriceThis paper introduces a novel on-line monitoring performance method of coal-fired power unit. Support vector machine (SVM) is used to predict the unburned carbon content of fly ash in the boiler and the exhaust steam enthalpy in turbine, which are two difficulties in the real time economic performance calculation model in coal-fired power plant.
Get PriceThis device monitors your grinding pressure at each of the grinding locations with a load cell. This information is then shown on a display on the side of the mill and/or in the control room. This data will help to calibrate your grinding pressure for proper fineness and thereby control capacity and mill DP. Another benefit is the ability to spread the load evenly across the main bearings.
