Abstract
Embodiments of the present disclosure describe burner (10) configurations used in an industrial process to convert methane to olefins, aromatics, and nanoparticles/nanomaterials. Both a vitiated coflow burner and piloted turbulent burner with inhomogeneous inlets are disclosed.
Claims12
A method of controlling secondary reactions of a burner of combustion products using injected methane, the method comprising:
- establishing a jet flame in coaxial flow of hot combustion products from a premixed vitiated coflow of gas passing through a porous plate or catalytic monolith, said jet flame established by gas exiting from a central tube;
- providing a tube positioner to translate the tip of the central tube to an offset height relative to the porous plate or catalytic monolith;
- and
- controlling the tube positioner to vary the offset height of the central tube tip in a dynamic manner based on chemical inputs, with said controlling resulting in different secondary reactions of combustion products from the burner.
A method of controlling secondary reactions of a burner of combustion products using injected methane, the method comprising:
- establishing a jet flame in coaxial flow of hot combustion products from gas passing through a porous plate or catalytic monolith, with said jet flame established by a piloted turbulent burner with inhomogeneous inlets and defining three concentric tubes;
- providing a tube positioner to translate an innermost one of the three concentric tubs to different positions relative to an intermediate tube;
- and
- controlling the tube positioner to vary the position of the innermost tube in a dynamic manner based on chemical inputs, with said controlling resulting in different secondary reactions of combustion products from the burner.
A burner for converting injected methane to olefins, aromatics and nanoparticles/nanomaterials, comprising:
- a plate through which a coflow gas passes, with a coflow flame established above the plate;
- a central tube passing through the plate and having a tip through which methane exits;
- an exit ring surrounding the plate, with said exit ring establishing a shear boundary of combustion products;
- a tube positioner for varying an offset height of the tube tip relative to the plate;
- and
- a controller for adjusting the offset height of the tube tip based on material inputs or desired output yield.
