Fly ash is the fine ash powder produced and collected at coal-fired power plants. When coal is ground and injected into burning chambers, it ignites and produces two types of ash: bottom ash and fly ash. As the names suggest, bottom ash, with its larger and heavier particle sizes, falls to the bottom of the combustion chamber whereas fly ash “flies” up with the exhaust stream. Fly ash is

The CBO process for fly ash beneficiation shows excellent potential. Values derived from avoided disposal costs, revenue from fly ash sales, environmental attributes and the ability to process of the ash indicate the potential market for this process. Work has begun on the next phase of process development and commercialization and includes site specific application studies (technical and

A facility can cost tens of millions of dollars, which suggests that it would be more attractive for larger power plants with access to large and stable markets. The construction of a thermal beneficiation facility may require significant plant modifications and systems integration; however, it does not specifically target ash fineness and uniformity.

This proven thermal technology allows for beneficiation of both wet or dry fly ash generated by or stored at electric power plants at a cost profile that is roughly one-third of the cost of competitive thermal technologies. The technology, which reduces loss on ignition (LOI), ammonia, activated carbon, moisture and chlorides, can also be deployed rapidly. Its unique small footprint, self

The least expensive method for ash beneficiation is enhanced quality control at the power plant; this is accomplished by monitoring the various ash streams for LOI and/or fineness and segregating the ash. The LOI in the ash is sometimes found to vary as a function of the load; that is, the lowest LOI produced during a constant load and higher LOI during periods of an increasing or decreasing

Fly Ash produced at different power plants or at one plant with different coal sources may have different colors. And particle size and shape characteristics of fly ash are dependent upon the source and uniformity of the coal, the degree of pulverization prior to burning, and the type of collection system used.

Coal ash beneficiation reuses coal ash from surface impoundments to produce cementitious products, like concrete. The Coal Ash Management Act (CAMA), as amended, required Duke Energy to identify three impoundment sites suitable for beneficiation projects.
