Revised Standard from Last Update.

1. SCOPE

1.1 This standard lays down guidelines for utilization of fly ash.

1.2 Fly ash may be collected from the flue gases, in thermal power plants, by mechanical collectors or electrostatic precipitators or a combination of both. It may be removed by “wet system’ or ‘dry system’. The ‘wet system’ involves mixing the fly ash with water and sluicing it to a settling tank or dumping areas. The ‘dry system’ involves removal of the fly ash indry form either directly by screw feeders discharging into transport vehicles from the hoppers or by means of pneumatic conveying system for further utilization or storage
