Power consumption of centrifugal blowers during throttling
Thread Content
What are the general conclusions regarding the power consumption of centrifugal blowers when throttling? I saw a statement today saying that when using a butterfly valve for throttling, the power consumption is higher than that when using inlet guide vanes. During operation, let’s discuss other energy-saving techniques and measures. Contribute to energy conservation and emission reduction!
Because butterfly valves present high resistance, the inlet guide vane control valve is essentially a multi-leaf control gate, which reduces resistance; it is best to use an inverter-driven motor for control, as this offers better energy-saving effects compared to using valves.
