A fuel heating system for fuel usable in a turbine engine. The fuel heating system may include at least one fuel heating chamber in communication with an exhaust stack of a turbine engine. The fuel heating chamber may be configured to allow exhaust gases to flow through the at least one fuel heating chamber. The fuel heating system may also include at least one conduit positioned in the fuel heating chamber. The conduit may be configured to receive fuel from a fuel source at a first temperature, allow the fuel to flow through the conduit, and exhaust the fuel at a second temperature that is higher than the first temperature.

I claim: 1. A fuel heating system for a turbine engine, comprising: at least one fuel heating chamber in communication with an exhaust stack of a turbine engine and configured to allow exhaust gases to flow through the at least one fuel heating chamber; and at least one conduit positioned in the at least one fuel heating chamber and configured to receive fuel from at least one fuel source at a first temperature, allow the fuel to flow through the at least one conduit, and exhaust the fuel at a second temperature that is higher than the first temperature, wherein the at least one fuel heating chamber is positioned in a corner of the exhaust stack of the turbine engine; and wherein the at least one fuel heating chamber is formed from at least one plate attached to a first wall of the exhaust stack and attached to a second wall of the exhaust stack that is positioned nonparallel to the first wall and wherein the heating chamber is defined by the plate, the first wall, and the second wall. 2. The fuel heating system of claim 1, wherein the at least one conduit comprises a serpentine shaped metallic conduit. 3. The fuel heating system of claim 1, wherein the at least one plate comprises a first plate having at least one exhaust gas orifice positioned over a second plate having at least one exhaust gas orifice, wherein the first plate is movable relative to the second plate to adjust a cross-sectional area of the at least one exhaust gas orifice of the second plate to control flow of exhaust gases into the at least one fuel heating chamber. 4. The fuel heating system of claim 3, wherein the first plate comprises a plurality of exhaust gas orifices, and the second plate comprises a plurality of exhaust gas orifices. 5. The fuel heating system of claim 4, wherein the plurality of exhaust gas orifices in the first plate are offset laterally from the plurality of exhaust gas orifices in the second plate. 6. The fuel heating system of claim 5, wherein the plurality of exhaust gas orifices in the first plate are offset laterally from the plurality of exhaust gas orifices in the second plate such that in a first position, the plurality of exhaust gas orifices in the first plate are aligned with the plurality of exhaust gas orifices in the second plate, and in a second position, the plurality of exhaust gas orifices in the second plate are covered by the first plate. 7. The fuel heating system of claim 5, wherein the plurality of exhaust gas orifices in the first plate are offset laterally from the plurality of exhaust gas orifices in the second plate such that in a first position, a portion of the plurality of exhaust gas orifices in the first plate are aligned with the plurality of exhaust gas orifices in the second plate, and in a second position, the portion of the plurality of exhaust gas orifices in the second plate are covered by the first plate. 8. A method of heating fuel usable in a turbine engine, comprising: passing fuel from a fuel storage location to a fuel heating system for a turbine engine, wherein the fuel heating system comprises at least one fuel heating chamber in communication with an exhaust stack of a turbine engine and configured to allow exhaust gases to flow through the at least one fuel heating chamber; and at least one conduit positioned in the at least one fuel heating chamber; receiving fuel from at least one fuel source at a first temperature; passing the fuel through the at least one conduit; and exhausting the fuel at a second temperature that is higher than the first temperature, wherein passing fuel from a fuel storage location to a fuel heating system for a turbine engine comprises passing fuel to a fuel heating system comprising at least one fuel heating chamber positioned in a corner of the exhaust stack of the turbine engine and formed from at least one plate attached to a first wall of the exhaust stack and attached to a second wall of the exhaust stack that is positioned nonparallel to the first wall, wherein the heating chamber is defined by the plate, the first wall, and the second wall; and wherein the at least one plate comprises a first plate having at least one exhaust gas orifice positioned over a second plate having at least one exhaust gas orifice, wherein the first plate is movable relative to the second plate to adjust a cross-sectional area of the at least one exhaust gas orifice of the second plate to control flow of exhaust gases into the at least one fuel heating chamber. 9. The method of claim 8, wherein passing fuel from a fuel storage location to a fuel heating system for a turbine engine comprises passing fuel to a fuel heating system, wherein the first plate comprises a plurality of exhaust gas orifices and the second plate comprises a plurality of exhaust gas orifices, wherein the plurality of exhaust gas orifices in the first plate are offset laterally from the plurality of exhaust gas orifices in the second plate such that in a first position, the plurality of exhaust gas orifices in the first plate are aligned with the plurality of exhaust gas orifices in the second plate, and in a second position, the plurality of exhaust gas orifices in the second plate are covered by the first plate.
