The process of producing fly ash is as follows Coal is mined from a quarry and transported to power stations where it is stockpiled into different grades. The coal is milled in large mills into a fine powder, whereafter it is blown through a series of pre-heaters into a furnace where it burns at +-.

For the coarse grade of fly ash, the lowest value of specific energy was about 12 kJ kg but for the fine grade of fly ash this was just 1 kJ kg. Off Spec Ash and Other Problems. A modern power station is likely to be generating between one and two million ton per year of fly ash.
The management of this fly ash has been a concern with various approaches for its beneficial use being investigated. This work presents the results of transesterification reaction using sunflower oil as feedstock with methanol and class F fly ash catalyst derived from a coal fly ash dump in South Africa to produce methyl esters (biodiesel).
Of CFA. The recovery of alumina from coal ash or clay are based on . the applications of hydrometallurgical processes such as acid or base leaching, precipitation, solvent extraction and re-crystallization [9-16]. Recently, Matjie  calcined the Sasol CFA from South Africa with calcium oxide under 1000~1200 C, then the calcined mixture.

Flue ash is also known as pulverized fuel ash, and flue gases from coal-fired power plants are delivered to the chimney by an electrostatic precipitator or other particulate filtration device and it is a very fine powder with spherical particles, less than 50 microns. Fly ash is a fine powder.
Fly ash is hydropholic and can be used as a cementitious additive. The ash, which is collected from chimney filters in coal-fired power plants, is composed of vitreous silica, alumina, iron oxide and lime. They can be used as a partial substitute for clinker and thus help to reduce CO2 emissions.
This paper details the laboratory investigation of optimising South African Class F fly ash content in a concrete mix to achieve a compressive strength requirement of 30MPa. Class F fly ash used in this investigation is considered as low in lime content compared to Class C fly ash.
Oct 29, 2021 South Africa has large coal reserves. It mainly burns coal to produce electricity at 13 existing coal-burning power plants, situated mainly in Mpumalanga, a province in the country’s east In South Africa, coal power generation results in at least 36 million tonnes of solid waste residue called fly ash being produced annually.That’s the equivalent of six dumps each the size of the Pyramid.
