Abstract In a surface combustor-heater being developed by the Institute of Gas Technology (IGT), heat-exchange surfaces are embedded in a stationary bed (porous matrix) of refractory material where gaseous fuel is burned. The overall heat-transfer rate from the combustion products to the embedded heat-exchange surfaces can be significantly enhanced. Also, by removing heat simultaneously with the combustion process, NOx formation can be significantly reduced. To prove this concept, the bench-scale surface combustor-heater has been tested. Preliminary experimental results have demonstrated the remarkable advantages, such as high combustion intensity (up to 0.44 X 10^6 Btu/h-ft2) with just one row of tubes, high heat flux to the embedded tubes (up to 83 X 10^3 Btu/h-tt2), high heat-extraction rate (up to 60%), as well as low combustion emissions (NOx as low as 10 ppm and CO as low as 50 ppm, both at 0% O2). The surface combustor-heater performance data are rather promising. Further research and development work is recommended to explore the interaction between combustion and heat transfer and to develop data for optimizing the design and unit scale-up.
