System and method for conditioning air flow to a gas turbine

A system for conditioning air flow to a gas turbine, comprising:

• a. a filter housing that defines a path for air flow to the gas turbine;
• b. an inlet to the filter housing, wherein the inlet defines a first cross-section for air flow into the filter housing;
• c. an outlet to the filter housing downstream from the inlet, wherein the outlet defines a second cross-section for air flow out of the filter housing, wherein the second cross-section is smaller than the first cross-section;
• d. a conditioning media that extends radially across the filter housing between the inlet and the outlet to adjust the temperature of the air flowing from the inlet to the outlet;
• e. a depth of the conditioning media;
• f. a density of the conditioning media;
• g. wherein at least one of the depth or the density of the conditioning media varies across the filter housing to reduce a temperature difference of the air flow across the second cross-section of the filter housing.

A method for conditioning air flow to a gas turbine, comprising:

• a. flowing air through a filter housing connected to the gas turbine;
• and
• b. flowing the air across at least one of a varying depth or a varying density of a conditioning media in the filter housing;
• c. conditioning the air flow to reduce the temperature difference of the air exiting the filter housing across a dimension of the filter housing.
