Question
A coal sample contains C=70%, O=23%, H=5%, N=0.4%, Ash=0.1%. Calculate GCV and NCV of the fuel.
Numerical
Solution
HCV = `1/100` [8080C+3500(H-O/8)+2240S)
= `1/100`[8080 X 70+34500(5-23/8)+2240X0)
= `1/100` [565600+73312.5]
=6389.12 Kcal/kg.
LCV = [HCV - 9100 X H X 587]
= [6389.12 - 9100 X 5 X 587]
= [6389.12 - 264.15]
= 6124.97 Kcal/kg.
