WATER PUMP COMMON PIPING LINE STRUCTURE OF GAS TURBINES

摘要

A water pump common piping line structure of gas turbines is provided to permit a neighbor water pump to supply water to a relevant gas turbine when one water pump has problems. Common lines(5) having vent lines(4) are connected to respective water supply lines(3a,3b,3c,3d) which connect gas turbines(1a,1b,1c,1d) and water pumps(2a,2b,2c,2d) in series. The common lines connect the water supply lines in parallel with each other. Drain lines(6) are branched from the respective water supply lines so as to recover water from the respective water pumps.
