Flue gas volume conversion
Thread Content
The flow rate of flue gas at standard conditions is 162,000 Nm3/h; the temperature at the flue gas inlet is 230°. The composition of the flue gas is as follows: CO2 – 4.2%, H2O – 15.2%, O2 – 8.8%, N2 – 71.8%, SO2 – 450 mg/Nm3, CHL – 50 mg/Nm3; the oxygen content on a dry basis is 11%. The amount of CaO fed in is 152 kg/h, and the amount of water used for atomization is 4.5 T/h. The temperature at the flue gas outlet is 170°. I would be very grateful if experts could help calculate the flow rate of flue gas at standard conditions as well as under actual operating conditions, along with a detailed calculation process. Thank you very much! ! ! ! !
Has all the atomized water turned into vapor? Under these conditions, atomization increases the water vapor volume by 4500/18*22.4=5600 Nm3/h; the outlet flow rate under standard conditions is 162000+5600=167600 Nm3/h. Assuming normal operating conditions, the flue gas is discharged at approximately atmospheric pressure. 167600*（170+273）/273=271966m3/h
Yes, all the water turns into steam. Thank you so much! ! ! ! !
Flue gas volume under standard conditions = 162000 Nm3/h / 22.414 mol
