What Is the Working Principle of 110kw High Pressure Centrifugal Blower Boiler Fan

Mar 13, 2025

The 110kw high-pressure centrifugal blower boiler fan operates based on the principle of centrifugal force.

When the fan's impeller rotates, driven by the 110kw motor, air is drawn into the center of the impeller. As the impeller spins at a high speed, the air is accelerated radially outward due to centrifugal force. The blades of the impeller impart kinetic energy to the air, increasing its velocity.

The air then moves through the volute-shaped casing of the blower. The volute casing is designed to gradually convert the kinetic energy of the air into pressure energy. As the air travels through the widening path of the volute, its velocity decreases while the pressure increases.

This high-pressure air is then directed to the boiler to provide the necessary combustion air supply. The fan's ability to generate high pressure allows it to overcome the resistance in the ductwork and any back pressure from the boiler. For example, in a large-scale industrial boiler, the high-pressure air from the blower helps in efficient fuel combustion by ensuring an adequate supply of oxygen, which is crucial for maintaining the proper heat generation process.
