working principle of compressed air energy storage shield machine
IET Digital Library: Compressed Air Energy Storage: Types, systems and applications
Compressed air energy storage (CAES) uses excess electricity, particularly from wind farms, to compress air. Re-expansion of the air then drives machinery to recoup the electric power. Prototypes have capacities of several hundred MW.
Compressed air
Principle. In compressed air closed shields the rotating cutterhead acts as the means of excavation whereas face support is ensured by compressed air at a sufficient level to balance the hydrostatic pressure of the ground. Debris is extracted from the pressurized excavation chamber using a ball valve-type rotary hopper and then conveyed to the
