1.Excess air for combustion is calculated using the assumption of complete reaction whether or not a reaction takes place.

2.For the typical combustion process the products are CO2 gas and H2O vapor.
In combustion processes, since any oxygen in the coal or fuel oil is inert, it can be ignored in the combustion calculations

3. A friend of yours says HHV and LHV are the same for carbon monoxide. Is the statement correct?

4. The percent excess air will always be the same as the percent excess oxygen in flue gas.

5. There are 3 significant figures in 3.9400E9

6. A mole is the number of molecules in one gram of a substance

7. API gravity is proportional to the specific gravity of the fuel

8. Parr formula is used to determine the rank of coal by determining calorific value on a moist mineral free basis
