Abstract
A fuel filtering apparatus for use in a gas turbine fuel system is provided. The fuel filtering apparatus includes a removable filter housing which receives and maintains a filter element therein to filter a fuel flow when the filter housing is positioned on the apparatus. The fuel filtering apparatus is also provided with a casing which is installed in-line in a portion of the fuel system. The removable filter housing alleviates the need for removal of the casing when a filter element is inserted and removed for cleaning and other routine maintenance. The fuel filtering apparatus also reduces pressure disruption within the fuel system.
Claims14
A fuel filtering apparatus for use in a gas turbine fuel system characterized by:
- a casing having a chamber and an inlet, an outlet, and a lateral opening in communication with said chamber;
- a filter housing, covering said chamber, having a transverse passageway extending therethrough;
- a filter element secured in said transverse passageway;
- sealing means, positioned between said filter housing and said chamber, for sealing said chamber;
- and,
- securing means for covering said lateral opening of said chamber with said filter housing.
A gas turbine fuel subassembly characterized by an apparatus comprising:
- a fuel filtering apparatus comprising a casing having a chamber and an inlet, an outlet, and a lateral opening in communication with said chamber, a filter housing removably seated within said chamber having a transverse passageway extending therethrough, a filter element secured in said transverse passageway, sealing means for sealing said chamber positioned between said casing and said filter housing, and securing means for covering said lateral opening of said chamber with said filter housing;
- a first pipe portion connected to said casing inlet to transport a fuel flow to said casing;
- and,
- a second pipe portion connected to said casing outlet to transport said fuel flow away from said casing, whereby said filter housing is removable from said casing without disconnecting said casing from said first and second pipe portions.
