Stack Losses for Low Sulphur Diesel Oil

Convert it to a percentage of the maximum capacity rating. Step 2. Calculate dry flue gas (DG)‚ lb / lb fuel. For Low Sulphur Diesel Oil containing 0.05 % sulphur and fired with negligible CO and hydrocarbons, the ASME formula for DG simplifies to: DG ‚ lb / lb fuel‚ = ( 11CO2dry + 8O2dry + 7N2 ) x ( C + 0.375S )

Combustion Efficiency and Excess Air

Typical excess air to achieve the highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil. 15 - 60% for coal. Carbon dioxide - CO2 - is a combustion product and the content of CO2 in a flue gas is an important indication of the combustion efficiency.
