Embodiments of the present disclosure describe burner 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.

[Problem] To provide a water heating apparatus which has a inverse combustion type burner installed within a case for a heat exchanger so as to cause heat to be transferred from an outer peripheral flange of the burner to the heat exchanger case. [Solution] This water heating apparatus is provided with: a fan for supplying combustion air; a chamber case which is connected to the fan and which has set therein a chamber where an air-fuel mixture is formed; a inverse combustion type burner for combusting the air-fuel mixture supplied from the chamber; a heat exchanger in which combustion gas generated by the burner is introduced into a case where water is heated; and sealing member which is installed between a peripheral flange of the chamber case and a peripheral flange of the case, wherein the burner is set inside the case, and an outer peripheral flange of the burner is anchored to an inner wall surface of the case.

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.

A flame holder system includes a support structure configured to support a plurality of burner tiles within a furnace volume. The support structure includes a frame supporting a support lattice. A number of burner tiles are arranged in an array on the support lattice. The support structure is configured to be assemblable without tools inside the furnace volume, using components that are sized to fit through an access port in a wall of the furnace.

A method of forming a gas burner membrane. The method comprises forming a plurality of holes in a sheet of material. The holes are formed by laser cutting a required pattern of holes in the sheet of material.

An outer peripheral edge part of the air-fuel mixture permeable member is connected to a portion away outward by a predetermined distance from an inner peripheral edge of the burner frame. Between the burner frame and the air-fuel mixture permeable member a clearance reaching the inner peripheral edge of the burner frame is secured at a position inward of the outer peripheral part of the air-fuel mixture permeable member. Preferably, a bent edge part formed on an inner peripheral edge of the burner frame, in a manner to be bent toward the air-fuel mixture permeable member. The amount of the air-fuel mixture to flow into the clearance is limited to a smaller amount.

A premix gas burner comprises a main body, a porous wall, a distribution chamber delimited by the main body and by the porous wall, and an entrance in the main body for introducing a premix of combustible gas and air into the distribution chamber. The main body comprises a cylindrical shape. The porous wall comprises a first porous wall segment and a second porous wall segment. The first porous wall segment and the second porous wall segment both comprise pores for the premix gas to flow from the distribution chamber through the pores, for combustion of the premix gas outside the distribution chamber. The first porous wall segment comprises or consists out of a shaped segment. The shaped segment is directed to the inside of the distribution chamber, such that when the burner is in use premix gas flows from the distribution chamber through the pores of the shaped segment to the inside of the shaped segment. The second porous wall segment comprises an annular porous wall segment. The annular porous wall segment is provided at the base of the shaped segment. The base of the shaped element is provided at the side of the shaped element opposite to the location of the entrance in the main body.

This disclosure provides systems, methods, and apparatus related to burner apparatus for lean premixed flames. In one aspect, an apparatus includes a burner plate, a burner body, and a mesh. A first surface of the burner plate defines a combustion surface for a fuel/air mixture. The burner plate defines a plurality of primary ports. The burner body defines a fuel-air mixing chamber. One surface of the burner body comprises the burner plate. The burner body defines an inlet for receiving air and a fuel in the fuel-air mixing chamber. The mesh is disposed in the fuel-air mixing chamber and is in contact with a second surface of the burner plate.

A plaque for a radiant heating system can include a main body defining an outer surface and a plurality of pores defined within the main body, wherein at least some of the plurality of pores are disposed in a non-parallel relationship with at least some others of the plurality of pores, or wherein at least some of the pores are parallel with each other. A burner assembly including a plurality of adjacently arranged plaques reduces the ignition time and delay for adjacent plaques after the central plaque has been ignited.

The present disclosure is related to a dual ring gas burner wherein the outer ring includes multipoint injection with bottom breathing and the inner ring works with top breathing. Two flame rings are included along with burner ports on the caps. As a result, better heating distribution is achieved along with greater ease in cleaning and combined simmer functions with high ratings by having the outer ring gas flow not interfering with the inner ring.
