Design of atmospheric gas burners. . ? Fig. 13.—Section views showing dimensions of five designs of injecting tubes In Fig. 13 and Table 2 are shown the dimensions of some of theinjecting tubes that were made and tested. These injectors weremade of brass and cut on a lathe. The end of the pipe burner,designated as the mixing tube, was reamed out, so that the inject-ing tube made a tight fit when inserted in the burner. Tube 34 Technologic Papers of the Bureau of Standards No. 5 is the type of injector which was used in the first part of theinvestigation. It was soon realized that,

Tube 34 Technologic Papers of the Bureau of Standards No. 5 is the type of injector which was used in the first part of theinvestigation. It was soon realized that, in order to draw definiteconclusions in regard to the design of the optimum injector, it wasnecessary to investigate the shape and length of the approach,the area of the throat, as well as the shape and length of the outlet.
