CONCRETE Optimizing the Use of Fly Ash in Concrete

In the production of fly ash, coal is first pulverized in grinding mills before being blown with air into the burning zone of the boiler. In this zone the coal combusts producing heat with tempertures reaching approximately 1500°C (2700°F). At this temperature the non-combustible inorganic minerals (such as quartz, calcite, gypsum, pyrite, feldspar and clay minerals) melt in the furnace and ...

Fly ash - Wikipedia

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.

Value in Waste: Fly Ash Reuse and Recovery Opportunities

One of the primary targets for recovery from fly ash has been alumina; most fly ash contains between 25 – 30% aluminum oxide (Al 2 O 3)¹. Some sources of fly ash in China have been shown to contain as much as 45% alumina. ² In addition to its use in producing aluminum metal, alumina is used throughout a host of industries as a catalyst, pigment, abrasive, and a long list of other materials.
