Abstract:
A portable forge having a burner shield with a combustible gas fitting at the top center thereof and an oxygen fitting in a side portion thereof coupled to an oxidizer ring tube with a plurality of oxidizer orifices disposed in the inner portion thereof for directing oxygen in a downward direction therefrom. An inner burner tube surrounds the gas jet orifice or fitting and terminates at the oxidizer ring tube. Disposed directly beneath the burner tube is a mixing chamber terminating in a venturi flare directly beneath the oxidizer ring tube. The mixing chamber terminates in a bottom portion within a top refractory pan which is spatially disposed over a base refractory pan which holds base slab, which in turn, carries a work piece being heated. The burner shield, together with the top refractory pan and the hardware therein, is hingedly attached to the base refractory pan and spatially disposed through a heat shield and top support member. In a second embodiment, a burner tube and mixing chamber are shortened with the oxidizer ring tube disposed at the top of the burner tube. |
