Given the “As Received” analysis of a coal:

     Sulfur           = 1.52%                  Hydrogen      = 6.36%

     Carbon         = 79.56%                Nitrogen        = 1.42%

     Oxygen         = 5.02%                  Moisture       = 2.51%

     Ash              = 6.12%

Using the ASH AND MOISTURE FREE ANALYSIS OF THE COAL, calculate the following:

a) Theoretical O/F ratio

b) Actual A/F ratio at 20% excess air

c) Gravimetric Analysis of wet gas

d) Volumetric Analysis of dry gas

e) LHV of the fuel in kJ/kg
