Recent Trends for Ash Disposal and Utilisation
In thermal power plant coal is being burnt and residue is left as ash. This ash is classified as bottom ash and fly ash. The ash generated below the furnace of thermal power plant is bottom ash which is around 20 of total ash and rest of 80 is fly ash. Bottom Ash is a coarse component of coal burnt ash and is not as useful as fly ash, because bottom ash remains toxic when recycled. But the fly ash when recycled, renders the toxic material and makes it safe for use. Fly Ash is a residue of coal combustion which is obtained from the coal based thermal power plant. It has been observed that the quality of ash produced is extremely good. They are fineness having low unburnt carbon and have high pozzolanic activity. It can be use as Pozzolana in manufacturing of building products like fly ash based bricks, cement, tiles, etc. It has advantage in agricultural industry as well as in the roads and embankment construction. The ash is a commodity that could help the company for producing wealth in long run if utilized in right direction. Fly ash is also considered as resource materials and the considerable amount of minerals can be extracted from it. This paper presents review on utilization of fly ash, that how it can be utilized in different applications, their properties and if proper utilization and disposal is not done, how it can affect our environment and life.
