Question

Q12. Estimate the theoretical amount of air required expressed in kg/T for complete combustion of a waste with a composition of CH120Os0N3? (10%)

Answer 1

Sol, Given - Estimate the expressed in kg/t with a Composition of theoretical amount of for Complete Combustion Go 1120 030 03. Air required of a waste In most of the Combusition processes the Dequired oxygen and not supplied as pute Oxygen. But is supplied as aid. - Air Contains al mol percent Og and 79 mol percent of Ng Cara + 209+ al costat Joa — (02 +2420 oC) CH4 +209+2(3.76 m2 -- Coat 2+90 +7.5a wa The minimum amount of air which Supplies the required amount of oxygen for Complete combustion of fuel is called theastical amount of air. General reaction a Catty + Vog (92 +3.7622] Vcoa Coa + VB H2O + Vaada The balance of atom yields the theartical amount of Orio is
