Chemistry

100 m3 of a fuel oil are burned per hour with 20 percent excessair in a steam generator. The fuel oil has a density of 926 kg/m3and the following mass composition: 87% C, 12% H2, 1% S. Air entersthe boiler at 100 kPa and 15 Â°C. Determine the following:
(a). The volumetric flow rate of the air (m3 /min) fed to theboiler;
(b). The flue gas molar composition on a dry basis, reportingall constituents to the nearest 0.001% and assuming completecombustion of the fuel oil; and
(c). The dew point temperature (Â°C) of the combustion flue gas,if the pressure exiting the boiler stack is 200 kPa.
(d). The mass flow rate of sulfur dioxide (SO2) emitted from theboiler, in metric tons per day, assuming complete combustion of thefuel oil.

The volume of fuel oil burned 100m3 The mass of fuel oil burned Volume X density 100 X 926 92600 Kg Mass composition 87 Carbon 12 hydrogen and 1 sulphur so the mass of carbon 87 X 92600 80562 Kg Mass of hydrogen 12 X 92600 11112 Kg Mass of sulphur 1 X 92600 926 Kg a Volume of air fed 100m3 hour 100m3 60 minutes so volumetric flow rate of th air 1667 m3 minute b The burning will See Answer
