Abstract: Low emissivity (low-E) coatings are applied onto surfaces of flare tips to achieve longer flare tip service life, improved flare tip structural integrity and/or a more stable flame pattern under a wide range of operating conditions. In accordance with some embodiments of the present invention, low-E coatings may be applied to the flare tip burner as well as associated internal and/or external component surfaces to reduce direct flame radiation and also conductive heat transfer. The low-E coating material preferably has an emissivity of less than about 0.80, more preferably between about 0.20 to about 0.78. The coating thickness of the low-E material is preferably between about 1 mil to about 25 mils, and more preferably between about 2 mils to about 8 mils. Coating densities of the low-E material in the coating will preferably be at least about 65%, more preferably between about 80% to about 100%.

Abstract: The performance of a combustion apparatus is improved by providing a burner tile therein which includes a coating of a high-emissivity (high-E) material. Preferably, the high-E material has an emissivity of greater than about 0.80, usually between about 0.85 to about 0.98. In some embodiments, the high-E material has an emissivity of about 0.92. The coating thickness on of the high-E material on the burner tile can be between about 0.0005 to about 0.025 inch, preferably between about 0.001 to about 0.002 inch. In especially preferred embodiments, the high-E material is ceramic. A burner tile comprising a coating layer of the high-emissivity material may therefore be incorporated into a combustion apparatus so as to improve its combustion performance.

Abstract: Systems and methods are provided whereby pumpable viscous fibrous material may be applied onto surfaces of high temperature process vessels while hot (i.e., while at or near such vessels' high operational temperatures of several hundreds up to several thousands of degrees Fahrenheit). More specifically, there are preferably provided a lance having a nozzle structure at a distal end thereof, and a pump system for pumping a pumpable fibrous refractory material to the nozzle. The lance has a length sufficient to allow it to be inserted into the high temperature process vessel so that the nozzle structure is adjacent an area in need of repair while an operator holds a proximal end thereof outside the vessel.

Abstract: Methods and apparatus for enhanced destruction of industrial waste gases include coating a high emissivity material onto to at least portions of the vessel walls of a direct fired incinerator, such as a thermal oxidizer, in order to enhance its incineration efficiencies, particularly for the incineration of volatile organic compounds (VOCs).
