Abstract
A constant-pressure air-storage cavern wherein the floor and the roof of the cavern are inclined at an acute angle with respect to the horizontal and the transition portion from the cavern into the air riser and into the water tunnel is expanded to form a dome and a sump, respectively. In the sump a vortex generator is provided.
Claims5
A constant-pressure air-storage cavern with hydraulic pressure compensation for air-storage gas turbine power stations utilizing an equalizing basin located above ground and comprising:
- air feeder means for feeding air to gas turbines of said gas turbine power stations;
- water tunnel means for forming a water seal and for connecting the storage cavern with said equalizing basin;
- and
- air riser means for connecting the storage cavern with the air feeder means wherein a floor portion and a roof portion of the storage cavern are inclined at an acute angle with respect to horizontal for minimizing adsorption of air in fluid stored in said storage cavern.
