Abstract

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.

Claims20

Dependent claims

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;
and
a 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.

Dependencies are inferred from the claim text.
