Ash Handling System in Thermal Power Plant. In thermal power plants, we use lot of coal for power generation. The coal has high amount of ash content, so these power plants generate lots of ash content. so we need a high efficiency system for handling the ash. The role of ash handling system plays a crucial role to maintain the environmental norms and following industry standards.
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.
Jun 25, 2011 The improper disposal and management of fly ash is the main problem for coal-fired thermal power plant (Senapati 2011 Tiwari et al. 2020).
Generally, when coal is burned in a pulverized coal-fired boiler, bottom ash generation is about 20% and fly ash generation is about 80%. Since only a small amount of ash is collected in economizer hoppers, air preheater hoppers and stack, ash collected in ESP hoppers is generally considered to be 80%.
