Centrifugal compressors and axial flow compressors
Thread Content
What operating conditions are suitable for centrifugal compressors? What operating conditions are suitable for axial flow compressors?
Axial flow is suitable for high flow rates and low pressure ratios, while centrifugal fans are suitable for lower pressure ratios with slightly higher theoretical values
It still depends on the application conditions – are axial flow fans more commonly used in the metallurgy industry, while centrifugal fans are more often used in the petrochemical and coal chemical sectors?
Flow rate is not an issue; both axial and centrifugal fans can be designed to handle large capacities. Our company’s axial-plus-centrifugal fans are capable of handling an air flow rate of 170 t/hr. Axial flow is suitable for low pressure ratios and offers higher efficiency ； Both high and low centrifugal pressure ratios can be selected, and the flow rate range is larger than that of axial flow fans; the centrifugal fans I have used have been capable of handling up to 500 t/h of air volume per unit, but the overall efficiency of such systems is about 3-5% lower than that of axial flow fans.
If one really wants to provide a comprehensive answer to this question, it’s quite complex. The person who posted above has already explained it in terms of flow rate and pressure; in addition, there are also factors such as the operating conditions mentioned by the original poster, cost estimates, and the manufacturer. It is recommended that the original poster take a look at the principles for selecting compressors; of course, the operating conditions are the most important factor, as nothing else matters if those conditions cannot be met.
