摘要:
A burner module for delivering a flow of chemical reactants to a combustion site of a chemical vapor deposition process includes a plurality of substantially planar layers. The substantially planar layers are arranged in a generally parallel and fixed relationship and define an inlet, an outlet and a passage fluidly connecting the inlet and outlet. At least one of the layers is a distribution layer having a plurality of apertures therethrough and fluidly communicating with the passage. The plurality of apertures collectively define a non-uniform pattern arranged and configured to improve the uniformity of a flow out through the outlet. Burner adapter and assembly embodiments are also included.

A burner module comprising a burner gas inlet block, a lower flow plate, an upper flow plate, a burner gas flow disperser, and a burner gas discharge block. The burner gas inlet block, the burner gas flow disperser, and the burner gas discharge block each comprising a plurality of channels separated by partitions. The partitions of the burner gas flow disperser and the burner gas discharge block comprising a knife edge. The upper flow plate and the lower flow plate each comprising a plurality of pressure holes in fluid communication with the plurality of channels. Additionally, the method of forming a glass sheet or ribbon using the disclosed burner module and a glass sheet or ribbon formed using the method.
摘要:
A burner for a vapour deposition process has a central nozzle for ejecting a glass precursor material, at least a crown of nozzles surrounding said central nozzle for ejecting a flame reactant, and a circular nozzle between said central nozzle and said crown of nozzles for ejecting an innershield gas, wherein the central nozzle has a concave shape in a cross section in the axial plane and, preferably, a symmetry about an axial plane.

Disclosed is a device and a method for maintaining and operating a flame. The device has a burner, a burner attachment having an outlet geometry, wherein on a side of the burner attachment facing away from the burner, an anode is provided on one side of the outlet geometry of the burner attachment. A dielectric is provided on the other side of the outlet geometry, wherein a cathode is located in the dielectric. The device and method: do not require continuous flame monitoring; positively influence the deposition behavior of layer-forming components of the fuel gas flame; and reduce the thermal impact of the burner and the operating costs thereof.
摘要:
The invention relates to a method for producing carbon black or other flame aerosols, comprising the following steps: the heat is removed from the flame by dissipation and/or radiation; a thin gas boundary layer is formed; the flow formed by the flame and the gas boundary layer is accelerated or expanded; the obtained aerosol is withdrawn; and the cooling surface is cleaned. The invention further relates to a device for carrying out such a method and a black carbon having a maximum pH value of 6.0, a maximum ignition residue of 0.1 percent, and a maximum 5 μm screening refuse of 200 ppm. The inventive black carbon can be used in rubber, plastic, printing inks, inks, inkjet inks, toners, lacquers, dyes, paper, bitumen, concrete, and other construction materials.
