Systems and methods are disclosed that may include providing a dual fuel burner in a superheater truck to burn wellhead gas produced from a wellhead in a first fuel burner and burn at least one of methane, ethane, propane, butane, gasoline, diesel, liquified natural gas (LNG), natural gas liquids (NGLs), and wellhead gas in a second fuel burner to heat water and/or other chemicals used in hydrocarbon production and/or well completion processes, including, but not limited to hydraulic fracturing (fracking). The first fuel burner may be integrated with the second fuel burner such that fuel rail fingers of the first fuel burner are interstitially spaced with fuel rail fingers of the second fuel burner. The first fuel burner and the second fuel burner may be operated independently from each other. The first fuel burner and the second fuel burner may alternatively be operated simultaneously with each other.

1. A dual fuel burner, comprising: a first fuel burner comprising a first fuel rail and a plurality of first fuel rail fingers connected in fluid communication with the first fuel rail, wherein each first fuel rail finger comprises a plurality of first combustion chambers, wherein the first combustion chambers each comprise a cylindrical combustion tube having an interior volume comprising a center portion and an annular portion, wherein the center portion and the annular portion are aligned with a cylindrical axis of the cylindrical combustion tube, wherein the first fuel burner is configured to burn a first fuel up flowing the first fuel up from a bottom of the center portion, and wherein air flows up from a bottom of at least part of the annular portion; anda second fuel burner comprising a second fuel rail and a plurality of second fuel rail fingers connected in fluid communication with the second fuel rail, wherein each second fuel rail finger comprises a plurality of second combustion chambers, wherein the second fuel burner is configured to burn a second fuel that is different than the first fuel. 2. The dual fuel burner of claim 1, wherein each of the first combustion chambers further comprises a combustion tube holder that is attached to the first fuel rail, and wherein one of the cylindrical combustion tubes is attached to the combustion tube holder. 3. The dual fuel burner of claim 2, wherein each of the cylindrical combustion tubes extends further from its the first fuel rail finger than each of the combustion tube holders. 4. The dual fuel burner of claim 1, wherein each of the first fuel rail fingers are movable relative to the first fuel rail. 5. The dual fuel burner of claim 1, wherein the first fuel is wellhead gas, and wherein the second fuel is at least one of propane, butane, gasoline, diesel, liquefied natural gas (LNG), and natural gas liquids (NGLs). 6. The dual fuel burner of claim 5, wherein the second fuel burner is configured to operate when the first fuel burner supplies less than about 3,500 British Thermal Units (BTU) per cubic foot. 7. The dual fuel burner of claim 5, wherein the second fuel burner is configured to operate when a pressure of the wellhead gas drops below about 1,000 pounds per square inch (psi). 8. The dual fuel burner of claim 5, wherein the first fuel burner and the second fuel burner are configured to operate simultaneously. 9. The dual fuel burner of claim 1, wherein each of the first fuel burner and the second fuel burner are mounted to at least one of a superheater truck, a trailer, a frac heater unit, and a skid. 10. The dual fuel burner of claim 1, wherein the first fuel rail fingers are interstitially spaced with the second fuel rail fingers. 11. The dual fuel burner of claim 1, wherein the first fuel rail fingers comprise a proximate end and a distal end, wherein the first fuel rail connects to the first fuel rail fingers at the proximate end, and wherein the second fuel rail is closer to the proximate end than the distal end. 12. The dual fuel burner of claim 1, wherein each first combustion chamber comprises a fuel nozzle in fluid communication with one of the first fuel rail fingers, and wherein the cylindrical combustion tube does not contact the fuel nozzle. 13. The dual fuel burner of claim 12, wherein the fuel nozzle is positioned within the first combustion chamber such that part of the cylindrical combustion tube is positioned below the fuel nozzle. 14. The dual fuel burner of claim 2, wherein each of the combustion tube holders at least partially envelope one of the cylindrical combustion tubes. 15. The dual fuel burner of claim 2, wherein each of the combustion tube holders comprise a 3 o'clock position, a 6 o'clock position, a 9 o'clock position, and a 12 o'clock position, wherein each of the combustion tube holders are attached to the first fuel rail at the 3 o'clock position and the 9 o'clock position, and wherein the air flows into the cylindrical combustion tube at the 6 o'clock position and the 12 o'clock position. 16. The dual fuel burner of claim 2, wherein each of the combustion tube holders has an inner diameter that is larger than an outer diameter of the cylindrical combustion tube. 17. The dual fuel burner of claim 2, wherein each of the combustion tube holders does not contact the first fuel or the second fuel. 18. The dual fuel burner of claim 2, wherein each first combustion chamber comprises a fuel nozzle in fluid communication with one of the first fuel rail fingers, and wherein the combustion tube holder does not contact the fuel nozzle. 19. The dual fuel burner of claim 18, wherein the fuel nozzle is positioned within the first combustion chamber such that part of the combustion tube holder is positioned below the fuel nozzle. 20. The dual fuel burner of claim 1, wherein the first fuel is not mixed with air prior to entering the first combustion chambers.
