Homework Statement
The chemical analysis of a fuel is determined to be: 84.60 wt% C, 11.12 wt% H, 1.95 wt % S and the balance, inerts. The fuel is consumed in a steam generating furnace with 33% excess theoretical air. The air is preheated to 190degreesC and enters the furnace at a gauge pressure of 225 mm Hg. The sulfur and hydrogen are oxidized to SO2 and H2O ; 95% of the C forms CO2 and the balance goes to CO. (Assume ideal gas)
Calculate the feed ratio of (m3 air)/ (kg oil) and the output on a mole fraction basis, dry and wet.
2. The attempt at a solution
Just going to give this a try as to how I should attempt this.
Have the fuel - 84.60% c
- 11.12% H
- 1.95% S
- 2.33% Inerts
33% excess air, thus we have 77% air consumed which is preheated to 190 degrees C at 255 mm HG
So we know the S + H -> SO2 and H2O while 95% C forms CO2 and 5% C forms CO
Could we say that we have a theoretical 100 moles which can then be divided down to 84.60 moles C and so forth.
We could then assume that we have 100 g of material and knowing that we have 77% of the air consumed work towards finding the ratio of this 77% to the 100g? I am slightly confused...
