Blower problems
Thread Content
Due to insufficient excess air in the heating furnace, a backup blower has been activated; what potential hazards could arise from the operation of both blowers together?
What to do if a backup blower fails? Check whether it’s possible to control the process through other methods. Both insufficient and excessive air supply in the heating furnace can reduce its efficiency and increase energy consumption

The control of fans is primarily based on flow rate, and the use of two fans also relies on the required flow rate as a reference. When one fan operating at full capacity is not sufficient to meet production needs, another fan must be brought into use, but the operating conditions for fans have their own specific characteristics. This requires two machines to work together: the one operating at full capacity must reduce its load so that the other machine can operate within its normal range. Otherwise, the fan will not be suitable for normal operation due to insufficient flow rate. Without control, the air volume will be too high, which is not suitable for production requirements.
That’s right. Are there any good ways to prevent this kind of problem from happening?
This situation occurs because the parameters of the fan were designed to be too low; from a long-term perspective, it is recommended to replace it
1. From the perspective of air supply, a single unit is insufficient; using two units together increases the air volume to meet process requirements. 2. From the perspective of fans, two centrifugal fans should be connected in parallel, with parameters and piping configurations kept as consistent as possible, to prevent surge caused by excessive pressure buildup in one of the fans
Roots blowers, right? There’s no problem; it’s just that there are no spare units available. It’s recommended to buy ones with a high air volume
Mm-hmm, it’s running in sync right now
