Answer 1

- About the flig ash: a) The two main morphologies in fly ast are & class of fly ash clous ċ fly as hij 3 The difference at there classes is the amount of calcium, silico, alumina and iron contenit in the ash, - The chemical properties of the fly. - ash are largely fluenced by the Chorfical Content at the coal burned, Arie anthracite, bituminous and lignite). b) the specific gravity of fly eashes: many significantly compasica to natural cores -) specific grauity o fly ash resulting Pn low weight as Empared to solis in an attractive property for Cits use ? - the specific gravity & fly ash caually ranges from 20 to 3.0, while its speatic Surface area may songe from 170 to 1000 ml/ka

TS c.) Disposal -> Fly ash once collected in : electrostatic' precapf tentor gets drons ported to fly ash bunkers using prescrired air & then get transported via truck or conveyers at the site and disposed by constructing a dry embrakement is called pry fly ash disposal' . - Fly ash once collected in electrostatic precipitator is mixed with water to form slerry and then this slurry is transported through pipe to the ash ponds or dumping areas near the plants and this is called as wet fly ash disposal..
