Utilizing Coal Bottom Ash from Thermal Power Plants
In Vietnam, a large amount of coal bottom ash (CBA) is being discharged from thermal power plants and has been making serious environmental pollution. It is essential to utilize the CBA to reduce environmental pollution. So, this paper presents a series of experimental studies in the laboratory using CBA as a partial replacement of aggregates in concrete pavement for rural roads.

Coal-Fired Thermal Power Plant an overview
A common requirement with fly ash conveying systems at coal-fired thermal power plants is that the fly ash should be conveyed to an off-site location for onward disposal. It is not unusual for this to be a distance of at least 1 km. The problem with increasing conveying distance is that for a given air supply pressure, the conveying-line pressure gradient decreases, and so there has to be a
