GAS TURBINE COMBUSTOR

摘要

A low cost gas turbine combustor. The gas turbine combustor has main nozzles annularly supported on a nozzle pipe base (11), and the main nozzles each have an oil fuel path for supplying oil fuel and a gas fuel path for supplying gas fuel. The oil fuel paths are arranged to penetrate the nozzle pipe base (11). Lengths of upstanding piping (21) raised from the nozzle pipe base (11) are connected to the oil fuel paths, respectively. Further, lengths of connection piping (22) interconnect in a polygonal shape the lengths of upstanding piping (21) in a minimum distance outside the nozzle pipe base (11). An oil fuel supply section (14) is connected to one of the lengths of connection piping (22) to distribute oil fuel to each oil fuel path.
