A furnace burns 10 kg/s of fuel oil (C = 86%, H = 10%, S = 4%). Measurements carried out at the base of the chimney indicate that the CO2 content is 12.8% and the temperature of the gases at this point is 200°C. Determine: a) The volumetric flow (m3/h) of gas in the chimney; b) The density of the flue gases at the chimney temperature.

Question
A furnace burns 10 kg/s of fuel oil (C = 86%, H = 10%, S = 4%). Measurements carried out at the base of the chimney indicate that the CO2 content is 12.8% and the temperature of the gases at this point is 200°C. Determine: a) The volumetric flow (m3/h) of gas in the chimney; b) The density of the flue gases at the chimney temperature.
Expert Solution
Step 1

Given,

The mass flow of fuel oil is 10 kg/s.

The mass% of C, H and S are 86%10% and 4% respectively.

 

Write the reactions for the combustion of C, H and S as follows:

C +O2  CO2H2 +12O2  H2OS + O2  CO2
