Flue gas volume conversion
Thread Content
I would like to ask everyone: given a flue gas volume of 204,064 Nm3/h, what is the flue gas volume under operating conditions? (Flue gas temperature: 130°C; local average atmospheric pressure: 1012.8 mbar.) Please list the calculation process in detail
204064*（273+130）/273=301237.33 Nm3/hour. Last edited by yourp on 2009-3-5 15:35.]
This post was last edited by MenDon’tCry on 2010-4-22 at 14:26. 204064××=301088.69 m3/h; the person above forgot to include the pressure correction factor.
Calculation formula: P1V1/T1 = P2V2/T2. V2 = 204064 × × = 301386.05 m3/h
Correct, ten points. Standard conditions = operating conditions × 273/(273 + temperature); thus, the flue gas volume under operating conditions = flue gas volume under standard conditions * (273 + t)/273
For desulfurization using the SDA method in a drying tower, given the volume of flue gas at the inlet under standard conditions, how can one calculate the volume of flue gas at the outlet under actual operating conditions? Could anyone please explain this? Thank you very much!
Post it again yourself; not many people look at old posts. Your question is not clearly stated, so it cannot be answered. The inlet gas volume is known, but it’s unclear how much gas is lost during the drying and desulfurization process; it’s also unclear what the conditions at the outlet are. How can the gas volume at the outlet be calculated?
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%, and the CaO flow rate is 152 kg/h. The amount of water used for atomization is 4.5 T/h, while 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! ! ! ! !
