  • TURBOMACHINE CONFIGURED TO BURN ASH-BEARING FUEL OILS AND METHOD OF BURNING ASH-BEARING FUEL OILS IN A TURBOMACHINE
    Publication number: 20130074509
    Abstract: According to one aspect of the exemplary embodiment, a turbomachine includes a compressor portion, a combustor fluidly connected to the compressor portion, and a turbine portion fluidly connected to the combustor portion and mechanically coupled to the compressor portion. The combustor portion is configured and disposed to burn ash-bearing fuel oils. The turbine portion includes a first stage having a first plurality of airfoils, and a second stage having a second plurality of airfoils. The first plurality of airfoils have a trailing edge discharge member. The second plurality of airfoils is clocked circumferentially relative to the first plurality of airfoils. The first plurality of airfoils are configured and disposed to direct an ash depleted flow upon corresponding adjacent ones of the second plurality of airfoils.
