The product gas from solid fuel combustion reaction has the following dry-basis molar composition: 72.00% CO2, 2.55% CO, 0.05% SO2, and 25.4 % O2. Pure oxygen is fed to the furnace in 20% excess of that required to burn the fuel completely. There is no oxygen in the fuel. Calculate the elemental composition (mole % of various elements) of the fuel, stating any assumptions you have to make to arrive at the answer.
