Mixer for cutting torch
Patent
·
OSTI ID:5910920
An improvement in a cutting torch assembly that obviates the tendency to have a flashback and sustained burning immediately adjacent the point of mixing of the fuel with preheat oxygen; including cutting oxygen valve and passageway, preheat oxygen valve and passageway, fuel gas valve and passageway, a head having a tip end for having a tip affixed thereto and having a head passageway for cutting oxygen and a head passageway for the mixture of fuel and oxygen; the improvement being characterized by an integral head mixer having within the head an incoming preheat oxygen passageway and incoming fuel passageway, a mixer disposed within a well in the head and having its central bore aligned with a longitudinally extending passageway in the head and having lateral passageway penetrating through the wall of the mixer and in communication with the fuel annular space of the well, the inlet end of the bore communicating with the preheat oxygen annular space of the well such that the fuel will flow laterally through the walls of the mixer at substantially 90/sup 0/ so as to flow into the oxygen stream and intimately admix therewith. A holder sealingly holds the mixer in the well. Also disclosed is a theory to explain why this elegant and subtle structure is so efficacious.
