Coal and Ash Handling in Thermal Power Plant MCQs with answers. Q2. Name the system that is mainly employed for the disposal of fly ash.
Maximum ash is collected in the front hoppers. In general, for low carbon ash, the coarsest ash is collected in the front hoppers, and the finest ash in the rear hoppers. Generally, when coal is burned in a pulverized coalfired boiler, bottom ash generation is about 20% and fly ash generation is about 80%.
