Heating furnace blower renovation
Thread Content
The actual load of the heating furnace is **lower than the designed load; therefore, even when the frequency of the blower is set at its lowest level, it is still necessary to use the inlet damper for control. However, closing the inlet damper too much results in large fluctuations. Are there any alternative methods to reduce the blower’s power output, apart from adjusting its frequency? Also, the magnetic coupler and the frequency converter should be the same, right? I hope the experts can give some advice!
A hydraulic coupling is also used to reduce speed, but its adjustment range is not as wide as that of an inverter, so it is not suitable for your application conditions. Your actual operating conditions are much worse than the designed ones; there are better ways to make improvements. I’ve sent you a message – add me on WeChat
