Managing leaks in a gas turbine system
First Claim
Patent Images
1. A method for managing leaks containing fuel in a gas turbine system, the method comprising:
- directing a compressed air and fuel mixture through a primary flow path through components of the gas turbine system, the components including a heat exchanger, a first reaction chamber, and a second reaction chamber;
receiving the compressed air and fuel mixture at a plurality of junctions between the components of the gas turbine system along the primary flow path;
directing a portion of the compressed air and fuel mixture, leaked from at least one of the plurality of junctions along a first leak path, to the second reaction chamber, downstream of the first reaction chamber, whereby the first leak path bypasses the heat exchanger; and
oxidizing at least a portion of the leaked compressed air and fuel mixture in the second reaction chamber.

Abstract
A mixture of air and fuel is compressed in a compressor of a gas turbine system. The gas turbine system includes components that define one or more fuel leak locations, and leaked fuel is directed from the one or more leak locations to a reaction chamber of the gas turbine system. At least a portion of the leaked fuel is oxidized in the reaction chamber. The energy released by oxidation of the leaked fuel can be converted to mechanical motion.

6. A method for managing leaked fuel in a gas turbine system, the method comprising:
-
directing a compressed air and fuel mixture along a primary flow path through a heat exchanger, a first reaction chamber, and a second reaction chamber of a gas turbine system; receiving the compressed air and fuel mixture at a leak location along the primary flow path, the leak location allowing the compressed air and fuel mixture to leak along a first leak path from upstream of the primary reaction chamber to downstream of the primary reaction chamber; directing a portion of the compressed air and fuel mixture, leaked from the leak location, along the first leak path to the secondary reaction chamber, whereby the first leak path bypasses the heat exchanger; and oxidizing at least a portion of the leaked compressed air and fuel mixture in the secondary reaction chamber. - View Dependent Claims (7, 8, 9, 10)
