In a microturbine, the air is compressed in which component?

In a microturbine, the air compression occurs in the axial flow compressor. This type of compressor is designed to move air through a series of rotating and stationary blades, which creates a significant increase in pressure as the air travels along the axis of the turbine.

The axial flow compressor is particularly effective for applications like microturbines because it allows for a more continuous and streamlined flow of air, resulting in efficient compression over a range of operating conditions. This design is effective in delivering high pressures while maintaining relatively low weight and size, making it suitable for the compact nature of microturbines.

The other types of compressors, while valid in different contexts, are not used in microturbines in the same capacity. Radial flow compressors generally work by impelling air outward from the center, which can lead to different flow characteristics. Positive displacement compressors are better suited for applications requiring a certain volume of air or gas to be moved at a specific pressure, and while centrifugal compressors can also be effective in various settings, the axial design provides optimal performance for the operational needs of microturbines.
