Abstract
Abstract Apparatus for preventing a blowout of a constant pressure air storage installation of a gas turbine power station is disclosed. The apparatus includes a subterranean air storage cavity, a water basin which is substantially at ground level, and a standpipe which connects the water basin to the subterranean cavity. At least an upper portion of the standpipe is arranged obliquely with respect to the horizontal. The apparatus also includes at least one ventilation pipe which is connected to, and in fluid communication with, the upper portion of the standpipe. An upper end of the at least one ventilation pipe is arranged above the water level of the water basin.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
In a constant pressure air storage installation of a gas turbine power station of the type having a compressor and a gas turbine and a subterranean air storage cavity with connecting lines for supplying air from the compressor to the storage cavity and from the storage cavity to the gas turbine, a water basin at a higher level than the cavity, and a standpipe connecting the water basin to the subterranean cavity, the improvement wherein: at least an upper portion of said standpipe is inclined with respect to the horizontal; and said standpipe includes a ventilation pipe which is connected to, and in fluid communication with, said upper portion of said standpipe to receive a water-air mixture forming during the charging of said air storage cavity, said ventilation pipe extending through the water basin with an upper end of said ventilation pipe extending above the water level of said water basin to permit the venting of air from said water-air mixture thereby preventing a blowout of said air storage cavity.
Claim 2
Dependent Claim
170 words
In a constant pressure air storage installation of a gas turbine power station of the type having a compressor and a gas turbine and a subterranean air storage cavity with connecting lines for supplying air from the compressor to the storage cavity and from the storage cavity to the gas turbine, a water basin at a higher level than the cavity, and a standpipe connecting the water basin to the subterranean cavity, the improvement wherein: at least an upper portion of said standpipe is inclined with respect to the horizontal; and said standpipe includes a ventilation pipe which is connected to, and in fluid communication with, said upper portion of said standpipe to receive a water-air mixture forming during the charging of said air storage cavity, said ventilation pipe extending through the water basin with an upper end of said ventilation pipe extending above the water level of said water basin to permit the venting of air from said water-air mixture thereby preventing a blowout of said air storage cavity.
Claim 3
Dependent Claim
219 words
In a constant pressure air storage installation of a gas turbine power station of the type having a compressor and a gas turbine and a subterranean air storage cavity with connecting lines for supplying air from the compressor to the storage cavity and from the storage cavity to the gas turbine, a water basin at a higher level than the cavity, and a standpipe connecting the water basin to the subterranean cavity, the improvement wherein: at least an upper portion of said standpipe is inclined with respect to the horizontal and wherein a length of the upper portion of said standpipe is substantially equal to one-quarter of a total length of the standpipe, said upper portion being arranged substantially directly beneath the water basin; said standpipe includes a ventilation pipe which is connected to, and in fluid communication with, said upper portion of said standpipe, an upper end of said ventilation pipe extending above the water level of said water basin; and said standpipe further includes an additional ventilation pipe which is connected to, and in fluid communication with, said upper portion of said standpipe, an upper end of said additional ventilation pipe being arranged abve the water level of said water basin, said ventilation pipes branching out from said upper portion of said standpipe toward said water basin.
Claim 4
Dependent Claim
219 words
In a constant pressure air storage installation of a gas turbine power station of the type having a compressor and a gas turbine and a subterranean air storage cavity with connecting lines for supplying air from the compressor to the storage cavity and from the storage cavity to the gas turbine, a water basin at a higher level than the cavity, and a standpipe connecting the water basin to the subterranean cavity, the improvement wherein: at least an upper portion of said standpipe is inclined with respect to the horizontal and wherein a length of the upper portion of said standpipe is substantially equal to one-quarter of a total length of the standpipe, said upper portion being arranged substantially directly beneath the water basin; said standpipe includes a ventilation pipe which is connected to, and in fluid communication with, said upper portion of said standpipe, an upper end of said ventilation pipe extending above the water level of said water basin; and said standpipe further includes an additional ventilation pipe which is connected to, and in fluid communication with, said upper portion of said standpipe, an upper end of said additional ventilation pipe being arranged abve the water level of said water basin, said ventilation pipes branching out from said upper portion of said standpipe toward said water basin.
