Calculation of off-gas from thermal deaeration tanks
Thread Content
Could someone tell me the method for calculating the exhaust gas discharge volume of a thermal deaeration tank? The parameters for the exhaust gas are 0.02 MPa, and the output capacity of the deaeration tank is 55 t/h. Thank you
How to calculate the steam vent volume of a deaeration tank? Is it just to take 0.5% to 1% of the force based on empirical values? Are there any theoretical calculation methods?
Can someone tell me? I. Technical specifications of the thermal deaerator: Model: XMC-55 ； Form: Rotary diaphragm type ； Working pressure: 0.02 MPa ； Rated output: 55t/h ； Operating temperature: 104℃ ； Water tank capacity: 30m3 ； Design pressure: 0.098 MPa. Steam source pressure: 0.2–0.5 Mpa, steam source temperature: 170–250℃ ； Inlet water temperature: 50°C for condensate water, 98°C for make-up water. Deaerator outlet water temperature: 102–104℃ ； Dissolved oxygen in deaerator outlet water: ≤15μg/L ； II. Actual operation data: Main steam pipe pressure: 0.4–0.5 MPa ； Pressure at the top of the deaerator deoxygenation head: 13-15 kpa ； Deaerator outlet temperature: 102-104℃ ； Replenishment desalinated water: 70-90°C; steam condensate: 40-60℃ ； At full load, the make-up water volume for the deaerator is 30–32 m3/h of demineralized water and 20–23 m3/h of steam condensate, for a total of approximately 50–55 m3/h.
