The carbon type is, in part, a function of the coal rank, with higher rank coals having a greater tendency to form anisotropic cokes. The amount of inertinite macerals in the coal certainly have a relationship to the amount of inertinite in the fly ash. Vitrinite contributes to the isotropic and anisotropic cokes.

A process is disclosed for converting low reactive fly ash to a highly reactive pozzolanic material by heating the fly ash until at least a portion of the fly ash melts; then rapidly cooling the fly ash. The resulting vitrified fly ash has improved cementitious properties relative to untreated fly ash.

Fly ash is used in concrete products and portland cement manufacturing if the CCP composition meets certain requirements. For example, the fly ash must have a minimum concentration of iron, alumina, and silica. Other important constituents include unburned carbon or LOI (loss on ignition), ammonia, sulfur, chlorides, and mercury.

Fly ash Wikipedia

Fly ash Wikipedia

+

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates that are driven out of coalfired boilers together with the flue gases. Ash that falls to the bottom of the boiler's combustion chamber is called bottom ash. In modern coalfired power plants, fly ash is generally captured by electrostatic precipitators or other particle .

Separation Technologies, LLC (ST) operates fly ash beneficiation facilities that produce high quality pozzolan, ProAsh(R), from poor quality fly ash. Its patented electrostatic separation process reduces the carbon content of fly ash to produce a low loss on ignition (LOI) product used as a partial portland cement replacement in concrete products.

Carbon content in the fly ash is measured by loss on ignition (LOI). If the carbon content in the fly ash were lowered, more fly ash will qualify to meet the requirement of use as cement admixture. Beneficiation processes are therefore used for the selective separation of unburned carbon from the fly ash.
