Process heaters and associated methods of processing with ultra-low pollutant emissions are provided. The process heaters and methods utilize a heat exchange tube having disposed therein a radiant permeable matrix burner at a first end of the tube. The tube further includes a thermally insulated insert disposed adjacent the radiant burner opposite an oxidant-fuel mixer that feeds the burner. The process heaters and methods act to reduce emissions of CO and NOx.

Gas fired process heater with ultra-low pollutant emissions

Methods and devices for gas mixture combustion on a surface of a permeable matrix are provided which produce or result in surface stabilized combustion (SSC) with increasing amounts of radiation energy emitted by the matrix surface and decreasing concentrations of pollutant components in the combustion products. The gas mixture is fed to a burner that includes a permeable matrix material having a first thermal conductivity and configured to preheat the combustible gas mixture as it travels through the matrix. The burner includes a plurality of thermal elements having a thermal conductivity higher than and disposed in thermal transfer communication with the matrix base material. The permeable matrix base material forms a combustion surface with at least a portion of the thermal elements exposed above the combustion surface. The gas mixture is combusted at or near exit pores and channels formed at the permeable matrix material combustion surface.

Radiant infrared gas burner

Methods of burning combustible gas mixtures on a surface of a permeable matrix providing surface stabilized combustion (SSC) with increasing amounts of radiation energy emitted by the surface of the permeable matrix and decreasing concentrations of pollutant components in the combustion products are provided. The gas mixture is fed to a burner that includes a permeable matrix material having a first thermal conductivity. The gas mixture is preheated as it travels through the permeable matrix material. The gas mixture is then combusted at or near exit pores and channels formed at a combustion surface of the permeable matrix material, the combustion surface at least in part coated with a coating material having a thermal conductivity less than the permeable matrix material thermal conductivity and a high optical transmittance in the infrared spectrum.
