A particular US-mined coal (typical gravimetric analysis: 80% C, 15% "ash", 3%

A particular US-mined coal (typical gravimetric analysis: 80% C, 15% "ash", 3% S, 2% H) is burned completely with 120% theoretical air. Reactants are to be assumed to be at 25 C, 1 bar, and the products are at 1 bar. The "ash" is an inert (non-combustible) solid material that doesn't react; it is collected and removed from the combustion chamber for disposal. Neglect the effect of enthalpy changes in the ash. Determine the following: Analysis of the reactants (you should make "THE TABLE" for the reactants), ash removed. Air-fuel ratio (include ash mass in fuel mass). Analysis of the products of complete combustion, ash removed. Dew point temperature Tap of the products. o Adiabatic flame temperature.
