At what speed range do microturbines typically operate?

Microturbines are compact, high-speed gas turbines that typically operate in the speed range of 50,000 to 120,000 rpm. This high operational speed allows microturbines to be efficient and effective in generating electricity and producing usable heat. Their design capitalizes on this high rotational speed to achieve optimal performance, including better fuel efficiency and lower emissions compared to traditional larger turbines.

While the other speed ranges listed may correspond to different types of turbines or machinery, they do not match the operational characteristics of microturbines. The correct speed range aligns with the intended use and design specifications for microturbines, emphasizing their specialized application in distributed generation systems, combined heat and power (CHP) systems, and various other applications where high efficiency and compact size are desired.
