Abstract:
A radiant wall burner apparatus. The apparatus includes an orifice for the introduction of fuel gas into an elongated mixing conduit for the directional flow and mixing of the fuel gas with combustion air provided through an inlet. The fuel gas and air mixture terminates through an adjustable burner tip. The radiant wall burner apparatus and burner tip allow for a two-leaf, adjustable radiant wall burner tip design that is less susceptible to heat deformation, flashback, and self-destruction, having fewer manufacturing issues, and having the capability to use hydrogen as a fuel source.

Abstract:
A method and a process to treat coke generated from a process application. The method includes the steps of recovering a mixture of coke particles and water or steam removed from at least one process application vessel. The mixture is directed to a cyclonic separator utilizing centrifugal force and gravity. Water is separated from the mixture in the cyclonic separator. Coke particles are separated from the mixture in the cyclonic separator and are directed to a thermal oxidizer. Coke particles are oxidized and gasified in the thermal oxidizer to produce gas and reduced particulate matter. The gas and reduced particulate matter are thereafter directed to a burner in the process application vessel.

Abstract:
A combined flow mixing, tempering and noise suppressing apparatus for a selective catalytic reduction system, and method of use thereof is provided. The suppressing apparatus is positioned downstream of a gas input duct of the selective catalytic reduction system in order to provide improved flow uniformity and reduced noise at the entrance to the SCR system with minimal pressure loss. The combined flow mixing, tempering and noise suppressing apparatus includes lobe depressions that extend toward a centerline axis of a gas input duct of the selective catalytic reduction system and alternating lobe protrusions leading away from the centerline axis. The combined flow mixing, tempering and noise suppressing apparatus can include a means for introducing a secondary stream, such as an air manifold or an air bustle in fluid communication with the selective catalytic reduction system.
Abstract:
A process is provided for estimating a three-dimensional (3D) radiance field of a combustion process in an enclosure. An on-line intensity-temperature calibration is performed based on an association between an intensity of an image pixel and an actual temperature associated with a selected region in the enclosure. The intensity of the corresponding image is transformed to a radiance image based on settings of an image-capturing device and the on-line calibration. A registration and alignment estimation of the image is performed based on positional information of the enclosure. The radiance image is aligned based on the registration estimation. The 3D radiance field having voxels of the enclosure is estimated based on a two-dimensional to 3D transforming of the aligned radiance images.

Abstract:
A radiant wall burner apparatus. The apparatus includes an inlet and primary fuel tip for introduction of fuel gas and air mixing in a mixing chamber. The fuel and air mixture are subject to a substantially uniform flow area from the point of discharge from a downstream portion of the mixing chamber up to the exit gap of the burner tip. The fuel gas and combustion air mixture terminate through the burner tip at a substantially uniform velocity. The radiant wall burner apparatus and burner tip allow for the substantially uniform velocity of the fuel gas and air mixture, reducing the potential for flashback of the burner tip.
