Answer :
Word Count : 1103
Ash handling is a critical aspect of solid waste management in thermal power plants, industrial boilers, and incineration systems where combustion of coal or other solid fuels generates large quantities of ash. Ash is produced in two primary forms: fly ash, which is fine particulate matter carried by flue gases, and bottom ash, which is coarser material that collects at the bottom of the combustion chamber. Proper handling of ash is essential not only to maintain plant efficiency but also to minimize environmental pollution and health hazards associated with airborne particulates and heavy metals. The ash handling process encompasses collection, transportation, storage, and disposal or utilization of ash, employing a combination of mechanical, pneumatic, and hydraulic methods to manage both fly ash and bottom ash effectively. The first step in the ash handling process is the collection of ash generated from the combustion of fuel. Fly ash is captured using electrostatic precipitators (ESP) or bag filters installed in the flue gas stream before it exits through the chimney. Electrostatic precipitators utilize high-voltage electric fields to charge fly ash particles, causing them to adhere __________ _______ _______ _____ ____ _______ _________ ________ ____ ____.
