Abstract World over for production of power pulverized coal fired boilers are extensively used. In India also 80% power is produced by pulverized coal fired boilers in National Thermal Power Plants. A very huge amount of ash is produced from these boilers. The quality of ash varies from plant to plant and from coke to coke depending on source of supply and type of combustion. In this dissertation an attempt has been made to categories problems and solutions related to it as given below:
For disposal of fly ash various kinds of ash ponds have been discussed, Design and economic aspects have been given. The effect of various type of ash/fly ash on air, land, water, agriculture living creature and human beings have been described. Some solutions have also been suggested. Experimental effect of addition of polymer carboxy methyl cellulose in slurry have been found to increase ash settling rates. For getting optimum ash settling rates 2ppm addition of carboxy methyl cellulose is found to be satisfactory. Utilization of fly ash for production of useful products has been mentioned.
