A component of a gas burner or an item to be placed over and/or in proximity of a gas burner, includes a core of fused silica glass and at least one coating comprising an electric conductive material.

A burner and associated methods are disclosed. The burner comprises a housing and a heat shield. The housing comprises an inlet for receiving gas, one or more outlets for expelling gas, and walls forming a gas cavity for directing the gas from the inlet to the outlet. The heat shield comprises a shield layer configured to cover at least a portion of at least one of the walls to thermally insulate the at least one of the walls from heat outside the gas cavity.

The disclosure relates to a gas-heated infrared radiation emitter comprising a burner plate, the burner plate serving as a combustion surface, and a radiating screen positioned on the combustion surface side of the burner plate. The radiating screen is formed by a mesh material or material with open pores, and has an inner face oriented towards the combustion surface side of the burner plate. The inner surface of the screen comprises at least a first portion and a second portion offset from one another in relation to the combustion surface, such that the distance between the combustion surface and the first portion is less than the distance between the combustion surface and the second portion.

A volatile organic compound burner includes a pre-heating bushing, a burner body, a porous medium and an ignition electric power source. The volatile organic compound is low-enthalpy fuel. The volatile organic compound burner functions in the same way as a combustion chamber of an internal combustion engine to use a combustible volatile organic compound as fuel and introduce the combustible volatile organic compound into the combustion chamber, adjust timely the fuel mixing ratio in the combustion chamber according to the temperature required for the oxidation of the volatile organic compound in the volatile organic compound burner, and ignite the volatile organic compound in the combustion chamber with an electronic ignitor. The volatile organic compound burner is structurally simple and widely applicable to simulation of the environment of oxidation of the volatile organic compound, has high cost to performance ratio, and reduces fuel cost and emission of air pollutants.

A process of partial oxidation is performed in a reactor which includes a reaction chamber and a burner assembly, wherein: the burner assembly has a single oxidant nozzle located within an fuel channel, said oxidant nozzle comprises a nozzle pipe and a nozzle outlet, the nozzle pipe and the fuel channel are arranged to produce a diffusion flame, the nozzle outlet has a shape with two or more elongate lobes projecting from a center of the nozzle pipe.

A combustion system includes a fuel and oxidant source and a flame holder. The flame holder includes a plurality of discrete slats arranged in parallel defining combustion channels between adjacent slats. Pairs of adjacent slats may be oriented to operate substantially as a V-gutter. The fuel and oxidant source outputs fuel and oxidant into the combustion channels. The flame holder holds a combustion reaction of the fuel and oxidant in the combustion channels.

The disclosure relates to a gas-heated infrared radiation emitter comprising at least one radiating screen, which is for example made of ceramic and/or metal, in the form of at least one plate comprising a lower main surface and an upper main surface that are distant from each other, and a plurality of through-prisms, which are preferably hollow, extending from the lower main surface to the upper main surface, each prism being defined by a polygonal base and by an axis. The prisms may be juxtaposed with one another so that their polygonal bases form a tiling of at least one portion of the lower and upper main surfaces of said plate.
