Blockage in the exhaust fan pipeline
Thread Content
Our company has a spray drying tower in its production process, and the ducts of the exhaust fans are always blocked, which prevents the entire system from functioning properly. Has anyone with experience encountered this issue? I would appreciate some guidance; thank you very much
It could be that the exhaust fan has too high an airflow rate, or it might be that the feed flow rate of the material is too low or too high. In addition to adjusting the air volume and feed rate, it is recommended to insulate the section of the exhaust fan pipeline that is blocked.
The pipes are being insulated, but how can we avoid blockages in them? Is there a good way to deal with the issue of high moisture content in the flue gas? The key question is: what temperature should be maintained? Expert, please give me detailed guidance: handshake
It’s hard to explain clearly right away; it depends on the properties of the material. Pipeline insulation is used to reduce the condensation of water vapor in the flue gas, which could otherwise lead to increased deposition on the walls.
Your coal isn’t mixed with waste materials such as tar or sludge, right?
No, the exhaust volume of the exhaust fan is low, and the pressure inside the main tower is a slight positive pressure, around 0.08 KPA. Would replacing the exhaust fan help to resolve the pipeline blockage issue?
