The design and fabrication of porous spherical burners for the production of spherically symmetric flows are reported. The burners are produced from sintering bronze powders in a spherical graphite mold, with the feed tube and the porous sphere produced in one piece. This offers the flexibility of installing tubes of varying sizes, yielding consistent results as compared to conventional methods in which the tubes are mechanically or chemically bonded to the bronze porous sphere. The versatility and quality of these burners are demonstrated through various images of spherical flames generated by issuing reactive gases through them in microbuoyancy conditions.
