For the furnace's design, consider using fuel oil as the source of en-

ergy with the following ultimate analysis (%w/w basis) to be burnt with

15% excess air.

• Assume complete combustion, determine the followings:

1. The mass of air required to burn 1 kg fuel oil.

2. The mass of flue gas produced from the combustion of 1 kg fuel oil.

3. The flue gas composition (%v/v).

4. The volume of flue gas produced (a t 300°C and 1 atm) from 1 kg fuel oil
