Abstract
A refractory powder flame projecting burner apparatus for lining repair or refractory fabrication in which oxygen-gas-entrained refractory powder is forcibly supplied to a burner where the oxygen gas mixes with fuel gas. A plurality of flame nozzles are provided in at least two parallel rows. A plurality of powder projecting nozzles are provided between and parallel to the rows of flame ports. A powder path is provided within the burner along the row of the powder projecting nozzles. A distributor having a plurality of axial grooves, with partitioned cavities at one end thereof, is inserted in the burner so that each cavity communicates with a plurality of the powder projecting nozzles. This refractory powder flame projecting apparatus forms a dense and durable refractory layer with a high yield.
