Abstract
A fiber matrix burner and method of manufacture in which a shaped burner element is formed by accreting a slurry onto a foraminous support. The slurry is comprised of ceramic fibers, a binding agent, a vaporizable filler, and a powdered, normally non-flammable aluminum alloy having a melting point between 660.degree. C. and 1,000.degree. C. After the drying and firing, a porous matrix of the fibers is formed which flamelessly combusts a fuel-air mixture. During combustion, the aluminum alloy inhibits growth of alumina crystals on the fiber surface to prolong burner life and, in addition, protects the burner both from extreme temperature and flashback.
