Abstract

A combustor assembly for a gas powered turbine includes a premix section to mix a first selected volume of fuel with a selected oxidizer. The premix section includes an injector plate that includes a porosity according to selected characteristics, such as pore size, pore density, pore distribution, and other selected characteristics. Therefore, the fuel may be provided through the porous plate to the premix area and a selected uniform flux.

Claims (13)

1. A power turbine including a combustor to combust a selected fuel in a selected oxidizer, comprising:

a premix chamber to allow mixing of the selected fuel and the selected oxidizer;

an oxidizer supply to supply the selected oxidizer to said premix chamber;

a fuel supply to supply the selected fuel to the premix chamber; and

a porous injector plate to inject the fuel into said premix chamber;

wherein the selected fuel is provided through the porous injector plate to mix with the selected oxidizer from said oxidizer supply.

2. The power turbine of claim 1 , wherein said premix chamber includes a void defined by a structure that allows the selected fuel to mix with the selected oxidizer in a substantially random manner to achieve the mixing.

3. The power turbine of claim 1 , wherein said oxidizer supply supplies a volume of compressed atmospheric air as the selected oxidizer.

4. The power turbine of claim 1 , wherein said porous injector plate includes a plurality of pores defined by said porous injector plate.

5. The power turbine of claim 4 , wherein each of said plurality of pores is formed by sintering a plurality of woven layers to form said porous injector plate including said plurality of pores defined by the plurality of sintered woven layers.

6. The power turbine of claim 1 , wherein said porous injector plate forms an acoustic barrier between a main combustion chamber and said fuel supply;

wherein the porous injector plate assists in allowing a substantially single flow direction of the fuel into the premix chamber.

7. The power turbine of claim 1 , wherein a pressure of said premix chamber is substantially below a pressure of the fuel supplied by said fuel supply.
