Materials Selection for Optimal Design of a Porous Radiant Burner for Environmentally Driven Requirements

Cellular Ceramics in Combustion Environments

“…[7,[38][39][40] According to the different sintering mechanisms and bonding types, various properties can be obtained. The cellular structure itself can be realized by replication techniques.…”

“…[2,[5][6][7] In contrast to metallic burners, cellular ceramics allow for higher operating temperatures, more efficient heat extraction through the radiating porous surface and/or volume and potentially better performance concerning flashback safety. [7] Despite recent scientific and technical success in developing new or improved burner concepts, a lot of problems remain to be solved in the field of materials science. As a result of the increased power density -up to several MW Á m À2 -caused by new designs, the requirements on the materials in terms of thermal shock and operating temperature have also increased.…”

Numerical study of effective heat conductivities of foams by coupled conduction and radiation

“…Polymer foams are used as insulators [2][3][4], metal foams as compact heat exchangers [5], ceramic foams as porous burners [6,7] or solar collectors [8][9][10], carbon foams as heat exchangers [11] or electrodes [12], especially for fuel cells [13]. Carbon [14] or metal [15] foams are used as a conductive network and as mechanical reinforcement for thermal energy storage materials, in combination with phase change materials (PCM).…”

Catalyzed Ceramic Burner Material

“…Metal and ceramic open cell foams were examined for porous radiant burner applications (Randrianalisoa, 2009) and the level of NOx and CO emissions as well as radiant efficiency were calculated. The author predicts that FeCrAlY with 95% porosity and cell size of 1.27 mm would have the lowest concentration of NOx and CO at an in-flux of 100 and 300 kW/m 2 .…”
