Regarding the air preheater interface issues
Thread Content
I’m not sure how others calculate steam-heated air preheaters. When the air is heated from room temperature to 125 degrees, with an air flow rate of 300 cubic feet per minute, should the inlet and outlet diameters be the same, or should the inlet be smaller and the outlet larger?
It’s fine to make them the same size, as the traffic volume remains constant
When there is a large temperature difference in the air, the densities differ; should the outlet connection be larger after expansion?
Our device has a small inlet and a large outlet
Could you tell me upstairs what the temperature of the air is, to what degree it is heated, what the air volume and wind pressure are, as well as the exact diameter of the inlet and outlet? Thank you
