Abstract
In the apparatus for preventing blowing out of the water supply in constant pressure air storage installations of gas turbine power plants, the layer of water, which is close to the surface in a cavern and in which dissolved air is concentrated, is withdrawn through tubes of a grate arrangement and a riser tube communicating therewith which extends in a water shaft and opens into a compensation basin, by introducing compressed air into the riser tube from an aeration tube. Consequently, the water of the cavern is transported into the water layer close to the surface in the compensation basin.
Claims5
In an apparatus for preventing the blowing out of a water supply from a water shaft in a constant pressure air storage installation for a gas turbine power plant containing a subterranean cavern for storing compressed air, conduit means for connecting said cavern and said gas turbine or a compressor thereof, respectively, a compensation basin having a floor and flow communicating with the water in said cavern through said water supply, the improvement which comprises:
- a grate of tubes firmly anchored in said cavern below a lowest permissible water level thereof;
- said tubes forming said grate being provided with suction holes;
- a header communicating with said tubes of said grate;
- said header extending from said cavern into said water shaft and continuing upwardly therein in the form of a riser tube opening into said compensation basin;
- an aeration tube and a source of compressed air connected thereto;
- said aeration tube having an open end;
- and
- said open end of said aeration tube opening into said riser tube at an upper portion of said water shaft.
