350CMH, 50Pa, what type of fan should be used? !
Thread Content
Flue gas: temperature ~100°C, flow rate 350 CMH, pressure drop of 50 Pa. I want to use an axial flow fan, but such a small model is not available on the market. Now, this smoke stream wants to be combined into a large chimney, with a pressure drop of about 50 Pa in that chimney. Does anyone have any good suggestions? !
Are fans of appropriate size all large? Can I slow them down by using a variable frequency drive?
This fan, which is only this small, still comes with variable frequency control – that’s quite troublesome.
A centrifugal fan can be used, but will it be possible to meet environmental regulations if the flue gas is directed into another large chimney?
Sure, as long as it doesn’t exceed the limit.
My facility has just been renovated; there’s now a hazardous waste incinerator and a gas boiler. Previously, it was fine for them to emit pollutants together, but now separate emission is required, with individual testing of the exhaust gases.
Environmental protection agencies in different places may have different requirements. Adapt to the local environment.
