Gas turbine combustor |
摘要 |
An object of the present invention is to provide a gas turbine combustor 3 that has, as means for atomizing liquid fuel, a fuel injection nozzle 12 using a fluid other than liquid fuel to atomize the liquid fuel and that can suppress a reduction in power generation efficiency resulting from a heat loss while promoting the atomization of the liquid fuel. The gas turbine combustor 3 is adapted to mix liquid fuel 18 with combustion air led from a compressor 1, burn the mixture and supply combustion gas 17 generated to a gas turbine 2. The gas turbine combustor 3 includes, on the upstream side thereof, a fuel injection nozzle 12 that atomizes the liquid fuel 18 into fine liquid droplets. The fuel injection nozzle 12 includes a first system 100 adapted to supply the liquid fuel 18 and a second system 102 adapted to supply a fluid for atomizing the liquid fuel 18. Low-boiling liquid fuel 21 is supplied to the second system 102 as the fluid. The second system 102 is adapted to heat and supply the low-boiling liquid fuel 21. |
