Abstract
An unsintered metal fiber burner is produced by mixing ceramic fibers with the metal fibers and binding the mixed metal-ceramic fibers together as a porous layer adherent to a foraminous support. By mixing ceramic fibers with metal fibers, the cost of a sintered metal fiber burner is reduced while the novel burner, because of the metal fiber therein, exhibits improved properties such as greater radiant efficiency, lower NO.sub.x emissions and increased durability.
Claims12
An unsintered fiber burner made with metal fibers mixed with ceramic fibers, said metal fibers being resistant to the high temperature and oxidizing conditions to which said burner will be exposed, the mixed fibers being bonded together as a porous layer adherent to a foraminous support by a binding agent in the aqueous suspension of said mixed fibers used to vacuum mold said unsintered fiber burner.
In a porous ceramic fiber burner, the improvement which comprises a metal fiber uniformly mixed with the ceramic fiber of said burner, said metal fiber being resistant to the high temperature and oxidizing conditions to which said burner will be exposed, and the weight of said metal fiber being not greater than five times the weight of said ceramic fiber.
