Embodiment Construction

[0078] a. Figure 1-5 Example system for

[0079] see figure 1 , a filtration system 10 for gas turbine air intake is provided. exist figure 2 , the system is shown in side view. The air to be filtered is indicated by arrow 12 . Air 12 passes through system 10 where it is filtered and then exits system 10 along arrow 14 where it is directed to a gas turbine (not shown).

[0080] See you again figure 1 , in the illustrated embodiment, the system 10 includes a housing 16 . The housing 16 includes a surrounding skirt 18 . The inner side of the skirt is the inner 20 .

[0081] In an example embodiment, the skirt 18 includes a front panel 21, a rear panel 22 ( Figure 2-5 ), the first side panel 23, and the second side panel 24 ( image 3 and 4 ). In one example, panels 21-24 may be made from sheet metal.

[0082] System 10 includes an inlet structure 26 . The inlet structure 26 defines an inlet flow face 28 . Generally, the inlet flow face 28 may be proximate to ...

Abstract

A gas turbine air filter system includes a housing having an interior, an inlet arrangement, and an outlet hood having an outlet arrangement. The inlet arrangement defines an inlet flow face for taking in unfiltered air. The outlet arrangement defines an outlet flow face for exiting filtered air. The inlet flow face and the outlet flow face are angled relative to each other. The angle can range between 45 to 135 degrees relative to each other. The system includes at least first and second stages of filter element arrangements held within the interior of the housing. The first and second stages of filter element arrangements are operably sealed within the housing such that air flowing through the inlet arrangement must pass through the first and second stages of filter element arrangements before exiting through the outlet arrangement. The outlet hood is free of the first and second stages of filter element arrangements.

Description

[0001] This application is a PCT international patent application with a filing date of March 6, 2014, requiring U.S. Provisional Application Serial No. 61 / 774,676 with a filing date of March 8, 2013 and U.S. Provisional Application with a filing date of February 21, 2014 Priority to Application Serial No. 61 / 942,844, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to filters and methods for filtering gas turbine intake air. Background technique [0003] Air intake filtration systems are typically used with gas turbines and operate by removing salt, dust, corrosive substances and water from the intake air to prevent them from entering the gas turbine and corroding and / or damaging gas turbine components. Gas turbine damage and corrosion can lead to operational inefficiency or failure and financial loss. [0004] A system that can be easily retrofitted into existing systems is desired. Furthermore, a system th...
