Spills of fly ash, such as the Kingston Fossil Plant coal fly ash slurry spill, can also contaminate land and waterways, and destroy homes. Power stations that burn coal also consume large quantities of .
Coal combustion products include: Fly ash; Bottom ash; Boiler slag; Flue gas desulphurisation gypsum; Others types of material such as fluidised bed combustion ash, cenospheres, and scrubber residues; Fly ash can be used to replace or supplement cement in concrete. In the USA, for example, more than half of the concrete produced is blended with fly ash.

flyash or coal ash is produced. In India coal reserve is mainly is of lignite so the power plant burns this and produces ash, Indian coal average ash content is 3538 percent.
Combustion of pulverized coal leads to emission of fly ash particles containing iron and other transition metals which have been identified as possible causative agents for adverse health effects [5]. Furthermore, a significant fraction of coal fly ash mass is contained in particles less than lm in aerodynamic diameter.
The use of processed fly ash in concrete continues to positively impact performance characteristics. In 2006, fly ash accounted for 20 per cent of coal combustion products worldwide as more than 15 million tons were used in the production of concrete (American Coal Ash Association, 2007).

The use of pulverized coal for power generation results in the production of vast amounts of fly ash in the United States. This research is concerned with the role of the physicochemical characteristics of fly ash in governing its pelletization and the strength of the product pellets in relation to their potential use as lightweight aggregate.
Since the annual production rate of fly ash from only one station in Nigeria may not meet local demands, there is therefore the need to explore the potential of the abundant bagasse ash as pozzolana .
Fiftysix percent of the coal ash produced in the in 2016 was recycled—establishing a new record and marking the second consecutive year that more than half of the coal ash produced was beneficially used rather than disposed.
