Jul 19, 2017· The removal of impurities in HCl treatment caused also an increase in the carbon content in the total mass of fly ash from 6.2% in raw fly ash to 8.1% in HCl-treated fly ash. NaOH treatment increased the carbon content not significantly to 6.6%.
A. Fly ash is produced through the combustion of coal used to generate electricity. After coal is pulverized, it enters a boiler where flame temperatures reach up to 1500 degrees Celsius. Upon cooling, the inorganic matter transforms from a vapor state to a liquid and solid state. During this process individual, spherical particles are formed.
particular amendment is used which is known as fly ash. Fly ash is the residual component of thermal power plants and it remains stored in ash ponds where it leads to undesirable environment. In recent scenario the main objective is to make use of the fly ash in the agriculture sector and to find out its effect on the health of the soil.
