Question
![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](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5df25c61-c835-497f-818f-ce260562c81f%2F1eb6267f-a2fb-4cea-abc6-6a3def6a1275%2F26zab9d_processed.png&w=3840&q=75)
