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% 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
