Questions & Answers on Ash handling system

We know that, fly ash is around 80% of total ash. So total fly ash generated is 58.8 X 80 / 100 = 47.04 MT. 3. A Boiler generates 20 MT of ash in a day, calculate total coal consumed in a day if coal has 5% of ash in it. Total ash generated =20 MT/day. Ash % in coal = 5%. Therefore total coal consumed = 20 / 5% = 400 MT.
