PURPOSE:To shorten the piping for return by connecting the return line immediately before a centrifugal separator in the fuel feeding system in a gas turbine for separating sodium atoms harmful for high-temperature combustion. CONSTITUTION:The fuel oil in a storage tank 1 is introduced into a centrifugal separator 6, and after sodium atoms harmful for high-temperature combustion are removed, switching to a clean tank 9 or the storage tank 1 is carried-out by a three-way valve 8, observing the concentration of sodium by a monitor 7. The fuel oil is supplied into a gas turbine from the clean tank 9. The return lines 15 can be connected immediately before the centrifugal separator 6. Therefore, the piping for return can be shortened markedly. |
