Abstract

A fuel delivery system for use with a flow of heavy fuel oil for a gas turbine engine may include one or more fuel lines in communication with the gas turbine engine and a magnesium mixing system positioned upstream of the one or more fuel lines. The magnesium mixing system may include a flow of magnesium and a flow of a carrier fluid, a carrier mixing chamber to mix the flow of magnesium and the flow of the carrier fluid to form a mixed carrier flow, and a heavy fuel oil mixing chamber to mix the flow of heavy fuel oil and the mixed carrier flow.

First claim

We claim:

1. A fuel delivery system for use with a flow of heavy fuel oil for a gas turbine engine, comprising:
one or more fuel lines in communication with the gas turbine engine; and a magnesium mixing system positioned upstream of the one or more fuel lines; the magnesium mixing system comprising a flow of magnesium and a flow of a carrier fluid, wherein the magnesium mixing system comprises a magnesium tank, magnesium pump, a carrier tank, and a carrier pump;
a carrier mixing chamber in fluid communication with the flow of magnesium and the flow of carrier fluid, wherein the flow of magnesium is supplied to the carrier mixing chamber from the magnesium tank by the magnesium pump and the flow of carrier fluid is supplied to the carrier mixing chamber from the carrier tank by the carrier pump, wherein the carrier mixing chamber is configured to mix the flow of magnesium and the flow of the carrier fluid to form a mixed carrier flow; and
a heavy fuel oil mixing chamber in fluid communication with the mixed carrier flow and the flow of heavy fuel oil, wherein the heavy fuel oil mixing chamber is configured to mix the flow of heavy fuel oil and the mixed carrier flow, wherein the carrier fluid comprises a diesel fuel.

2. The fuel delivery system of claim 1 , wherein the one or more fuel lines comprise a flow divider.

3. The fuel delivery system of claim 2 , wherein the flow divider comprises one or more manifold in communication with the one or more fuel lines.

4. The fuel delivery system of claim 1 , wherein the carrier mixing chamber comprises one or more angled counter flow nozzles in communication with the flow of magnesium.

5. The fuel delivery system of claim 1 , wherein the heavy fuel oil mixing chamber comprises one or more angled counter flow nozzles in communication with the mixed carrier flow.

6. The fuel delivery system of claim 1 , wherein the flow of heavy fuel oil and the mixed carrier flow mix to form a homogenous flow.

7. The fuel delivery system of claim 1 , further comprising a main fuel pump upstream of the magnesium mixing system.

8. The fuel delivery system of claim 1 , further comprising a clean fuel tank upstream of magnesium mixing system.

9. The fuel delivery system of claim 1 , further comprising a centrifuge upstream of magnesium mixing system.

10. The fuel delivery system of claim 1 , further comprising a raw fuel tank upstream of magnesium mixing system.

11. A magnesium mixing system for use with a flow of heavy fuel oil for a gas turbine engine, comprising:
a magnesium tank and a magnesium pump for supplying a flow of magnesium;
a carrier tank and a carrier pump for supplying a flow of a carrier fluid;
a carrier mixing chamber in fluid communication with the flow of magnesium and the flow of carrier fluid, wherein the flow of magnesium is supplied to the carrier mixing chamber from the magnesium tank by the magnesium pump and the flow of carrier fluid is supplied to the carrier mixing chamber from the carrier tank by the carrier pump, wherein the carrier mixing chamber is configured to mix the flow of magnesium and the flow of the carrier fluid to form a mixed carrier flow; and
a heavy fuel oil mixing chamber in fluid communication with the mixed carrier fluid and the flow of heavy fuel oil, wherein the heavy fuel oil mixing chamber is configured to mix the flow of heavy fuel oil and the mixed carrier flow, wherein the carrier fluid comprises a diesel fuel.

12. The magnesium mixing system of claim 11 , wherein the carrier mixing chamber comprises one or more angled counter flow nozzles in communication with the flow of magnesium.
