Transport of Bulk Fly Ash from Thermal Power Plants to Cement Factories:

As cement plants need dry flyash, some of the power plants earlier made arrangement for loading of flyash in the trucks directly from ESP hoppers which used to cause severe air pollution due to fugitive dust emission. As a follow up of the recommendations of CPCB under Corporate Responsibility for Environmental Protection (CREP), thermal power plants subsequently took initiatives to construct silos for intermediate storage of dry flyash and made arrangements for proper loading of flyash to the trucks. Flyash from these silos after loading is transported to the cement plants by Bulkers.

Flyash transportation has many challenges like distance to be transported, form of ash i.e. dry or wet ash, user’s requirement , economic feasibility , requirement of surrounding vicinity and many more site specific issues. Over and above, in any case control of dust emission during transportation is prime concern and more challenging being a non-point source of pollution and larger area coverage due to movement from one place to other passing through various receptors. As flyash is used by different users for different purpose such as cement manufacturing, brick manufacturing, mine back filling, road construction and filling of low lying area, the handling and transportation have to accordingly suggested. Following modes of transportation and precautions, to avoid fugitive dust emission are, therefore, suggested for different end users of flyash or bottom ash as the case may be:
