OSTI ID:6679093
An enhanced infra-red natural gas combustion technique has been developed in both the laboratory study and in the field testing. Firing rates as high as 142 KBtu/hr/sq ft were tested with a radiant efficiency better than 45%. At the normal firing rate of 120 KBtu/hr/sq ft, radiant fluxes on the order of 60 KBtu/hr sq ft were obtained. In addition, the major emission pollutants, NOx is below 20 ppm. A desired turndown rate of 2.5:1 has been achieved. The performance of the surface combustion inside the porous ceramic has been modeled. The numerical code has been used in the burner optimization design. In the field evaluation, the component durability, emissions and fuel savings, along with the productivity rate and product quality improvements have been evaluated. Even though a number of technical difficulties were encountered, the new gas fired radiant burner shows great potential for a variety of infra-red heating applications.
