A method and assembly for supplying heat in the desired pattern while suppressing the production of nitrogen oxides and carbon dioxide. The assembly includes a fluid mixture nozzle assembly in fluid communication with an external conduit and a radiant section of a fired process heater. The fluid mixture nozzle assembly includes an open mixing channel having an upstream converging section, a midstream mixing section, and a downstream diverging section for entraining a fluid mixture with vitiated flue gas combustion products. The fluid mixture nozzle assembly is installed in the wall, floor, or ceiling of the fired heater.

Method and device to reduce emissions of nitrogen oxides and increase heat transfer in fired process heaters

A method and device for reducing emissions of nitrogen oxides and for increasing heat transfer in a fired process heater is disclosed herein. The invention relates generally to the combustion of fuel using some proportion of air as the oxidant which leads to the production of oxides of nitrogen, and more particularly to a method and device that reduces the production of nitrogen oxides from combustion, promotes the appropriate distribution of temperature to reduce fouling of the process tubes in a fired heater, and increases the efficiency of heat transfer to the same process tubes.
