Gas pressure regulated atomizer tip for gas/oil burner

Abstract: A BURNER SUITABLE FOR FIRING A GASEOUS FUEL OR A COMBINATION OF A GASEOUS AND A LIQUID FUEL WITH THE GAS BEING USED TO ATOMIZE THE LIQUID FUEL. PRIMARY GAS IS INTRODUCED TANGENTIALLY INTO THE OIL STREAM IN THE THROAT OF A VENTURI NOZZLE DESIGNED TO EXPAND THE MIXTURE. SECONDARY GAS DISCHARGES THROUGH AN OUTER ANNULUS AND IMPINGES ON THE GAS-OIL MIXTURE DISCHARGING FROM THE VENTURI NOZZLE. THE SIZE OF THE ANNULUS FOR ADMITTING THE SECONDARY GAS IS RENDERED ADJUSTABLE BY AUTOMATICALLY MOVING THE OIL ATOMIZING NOZZLE IN AND OUT OF SAID ANNULUS, SO AS TO MAINTAIN CONSTANT GAS PRESSURE IN THE PRIMARY GAS TUBE AT ALL GAS INLET RATES. THE VELOCITY OF THE MIXTURE DISCHARGING FROM THE NOZZLE WILL THEN BE CONSTANT AT ALL GAS FLOW RATES. THE BURNER HAS GIVEN EXCELLENT RESULTS IN ATOMIZING FUEL OIL WITH GAS FLOWS AS LOW AS 17% OF THE TOTAL B.T.U. FIRED AT A HIGH FIRING RATE (30 G.P.H. OIL EQUIVALENT TOTAL FUEL IN THE CASE OF THE BURNER TESTED), AND ALSO WITH 50% GAS AT A LOW FIRING RATE (10 G.P.H. EQUIVALENT TOTAL FUEL).

Ladle shroud apparatus

Abstract: Apparatus for use in positioning a pouring tube on a bottom pour nozzle of a hot metal casting vessel including a pouring tube support carriage having universal or two dimensional movement in a horizontal plane and pouring tube transfer car mounted on the carriage to extend the pouring tube from an inboard position adjacent the carriage to an outboard position in alignment with the bottom pour nozzle. The apparatus is designed to raise and lower the pouring tube with respect to the bottom pour nozzle when in alignment therewith. The apparatus is also provided to move the pouring tube from an inboard vertical position to a horizontal travel position and finally to a vertical outboard position with the bottom portion of the pouring tube projecting into the molten metal bath of a tundish positioned beneath the casting vessel and the top of the pouring tube engaging the casting vessel bottom pour nozzle. The pouring tube transfer car is designed to be rapidly withdrawn in an emergency.

Method and apparatus for measuring roll gap and alignment for continuous casters

Abstract: Strand-like apparatus for measuring roll position, i.e., roll gap and/or roll alignment, is moved through a caster between roll faces of a series of oppositely spaced pairs of conveyor rolls which define either a straight or curved strand travel path. Apparatus includes carrier means having resiliently deformable parallel sensing surfaces with an elastomeric core, and plural lateral and plural diagonal inductive distance measuring means pivotally linked to the sensing surfaces for generating roll gap and alignment signals. These signals are recorded. Single and multiple harness means attach single and multiple measuring apparatus to a powered starter bar at one or more lateral strand axes, thereby to make lateral roll position measurements during multiple or single passes, respectively.
