New Delhi, India – Handling of coal and fly ash are a major challenge to the engineers in the thermal power plants. An efficient coal unloading system is the key to the movement of coal rake for optimum utilisation. High Concentration Slurry Disposal (HCSD) systems have proved to be very successful and economic for pumping of ash to the ponds.
An ash handling system consists of some subsystems such as bottom ash (BA), fly ash (ESP/air heater), ash water, and ash disposal systems. The ash handling system may be dry (dry pneumatic conveying is more popular now on account of retention of original characteristics of fly ash and its utilization), semiautomatic wet, and a wet system.
