A common requirement with fly ash conveying systems at coalfired thermal power plants is that the fly ash should be conveyed to an offsite location for onward disposal. It is not unusual for this to be a distance of at least 1 km. The problem with increasing conveying distance is that for a given air supply pressure, the conveyingline pressure gradient decreases, and so there has to be a ...

Abstract. Continuous variations in coal quality have a strong influence on operation of thermal power plants. However, in absence of realtime measurements of quality, the operators remain partially blind to the actual coal being consumed, leading to suboptimal operation. A twostage solution is proposed for realtime soft sensing of coal type.
