The following analyses on an "sir-dried" basis were made on the same coal. partial Ultimate analysis: 78%C, 5% H, 2.5%N, 2.5%S and 4% ash proximate analysis: 4.5% moisture and 26.5% VCM Required: a) complete Ultimate and proximate analysis of the coal b) Modified ultimate analysis of the coal: C, N+S, combined water, net hydrogen, ash, moisture c) analysis of the VCM; FC, net H2, cH2O, N+S d) The HHV of coal using Dulong's Formula: HHV = 14550C +62028(H-0/8)+ 4050S (in mass fraction) e) The HHV of the VCM of the coal in BTU/lb f) The HHV of coal using Calderwood's equation: C =5.88+0.00512 (HHV-40.5S) +0.00053[80 - 100(VCM/FC)]1.55 g) The volume of air theoretically required at 70F and 1 atm per pound of coal. h) If the refuse contains 80% ash, 2.89%VCM, and the rest FC, calculate the percent energy lost in the Refuse. i) Calculate the amount of carbon in the VCM in the refuse i) Compute the Orsat analysis of the flue gas assuming complete combustion
