Why is an axial flow fan chosen over a centrifugal fan for the catalytic main fan?

Why choose axial flow over centrifugal?
Axial flow fans have relatively flexible adjustable static blades, offer high air volume and efficiency, and are mainly suitable for systems with large processing capacities.
I remember that axial flow fans are suitable for applications with high flow rates and low head pressure. I’m not sure if it’s correct; I’ll check it at work
It should be the axial flow type, which offers flexible adjustment, high efficiency, and a high head capacity
The design institute designs it based on the processing capacity of your facility. Previously, for catalytic units with a capacity of less than 1 million tons, centrifugal designs were used, while those with a capacity of over 1 million tons also employed centrifugal designs
Well, I mainly haven’t seen centrifugal types; I use axial-flow ones in my installations
The axial-flow stator blades are adjustable, offering great operational flexibility and high flow rates, making them suitable for operation under various conditions in catalytic units
The centrifugal main fan we used in the past is actually older than me; P. In comparison, the axial flow fan is more flexible, and its adjustment accuracy is also higher than that of the centrifugal fan.
