Vent volume of the rotary film deaerator
Thread Content
I would like to ask the teachers here: does anyone know how to calculate the exhaust volume of a rotary film deaerator? The premise is that the deaerator has a rated output of 80 t/h, and the oxygen content in the feedwater is ≤0.007 mg/L. The technician here said the displacement is 80 kilograms; I’m not sure exactly how that is calculated. I hope the experts can give some guidance.
Well, I don’t know the answer to this question either; if anyone knows, please give some advice
Ask the manufacturer directly; that’s more specific.
The displacement is three thousandths of the intake volume
Oh, thank you, I’ll take that into account. . .
The exhaust volume of a rotary membrane deaerator is generally between one thousandth and three times the rated output of the deaerator
【Reply to Floor 6】 Yes, I remember the thermal engineering manual stating that the content of non-condensable gases is around 0.3 percent
The exhaust volume is more than 3%; around 10% of the steam consumption is a more realistic figure.
