Mettler Gas Burner

This is a low gas pressure, atmospheric air pressure, multijet, multiunit type of gas burner. It consists of a number of tubes within which the gas and air are mixed, heated, and ignited. The tubes are holes formed in a thick refractory block that protects the gas manifold from the heat of the flame and provides an incandescent zone at the mouth of each tube, which heats and ignites the mixture. The gas is supplied under pressure to each tube from a resulting agitation and mixing of the gas and air within the tube. The air is drawn into the furnace through the tube by reason of the draft within the furnace. It is claimed that the burner effects complete combustion of the fuel with only 12 to 14 percent of the air in excess of that theoretically required for complete combustion.
This burner has eight burner tubes and consists of three principal parts, the refractory block in which the tubes are formed, the gas manifold, and the air damper. The gas manifold is a rectangular box that fits against the back of the tube block and has cylindrical openings in line with the tubes. In each tube opening in the manifold are cast the fours jets through which gas is supplied to the tube. The damper is a hinged door that fits over the back of the gas manifold and controls the flow of air into the air tubes.
This burner, which is 11 inches square, burns 1,500 cubic feet of natural gas an hour at 3-ounce gas pressure, or 2,400 cubic feet at 10-ounce pressure.
