Title: Method and apparatus for feeding an oxidant  within a furnace enclosure
Inventor: SOLANO WILLIAM E

Granted: 1981-12-22
Abstract: ABSTRACT OF THE DISCLOSURE     Method and apparatus for feeling an oxidant such as air and/or a fuel rich gas within the confines of a substantially air tight enclosure employed in the heat treatment of volatile containing materials which are deposited on the floor of a rotary hearth mounted within the enclosure   The oxidant is admitted into the furnace enclosure through concentrically arranged rows of inlet openings formed in the roof of the enclosure.  The oxidant mixes in the upper portion of the enclosure with the volatiles evolved from the materials and combusts therewith and following combustion of the said oxidant and released volatiles the waste gases of com-bustion are caused to travel radially outwardly to a peripherally mounted exhaust  manifold whereas the materials undergoing heat treatment or the hearth are gradually advanced from the point of entry thereof to a centrally located discharge outlet.  Means are provided in the exhaust manifold to cause said oxidant and waste gases of combustion to travel in a line of direction outwardly of the enclosure and into the said exhaust manifold.  Thus, the direction of flow of the oxidant and waste gases of combustion within the enclosure is counter-current to the direction  of travel of the materials undergoing treatment on the hearth.

A timing capacitor in a motor speed control portion of the circuitry has a constant sum of resistances in the charge and discharge paths for fixed frequency of power pulses applied to the motor.  The timing capacitor is electrically connected to a wiper arm of a variable resistor located in both the charge and discharge paths such that resistance may be shifted between the paths to vary the duty cycle of the pulses over a wide range.  A pulse generating portion of the circuitry includes a threshold comparator and a trigger com-parator to respectively monitor the voltage on the timing capacitor for high or low conditions and cause a bi-stable circuit to change output states upon the occurrence of either condition to generate a train of pulses.  The bi-stable circuit is adapted to control the conductive states of transistors in series connection between the motor and the power source to apply repetitive constant-freguency, variable duty cycle pulses of power from the power source to the motor in accordance with the train of pulses.  Related methods are also disclosed.

Abstract: LOW LOAD COAL BUCKET            Abstract of the Disclosure An improved fuel-air admission assembly incorporating a split coal bucket which permits a pulverized coal-fired furnace to be operated at low loads without the use of auxiliary fuel to provide stabilization.  The split coal bucket comprises an upper and a lower coal nozzle pivotally mounted to the coal delivery pipe, the upper and lower coal nozzles being independently tiltable.  When the furnace is operating at low loads, the primary air and pulverized coal stream discharging from the coal delivery pipe is split into a first and a second coal-air stream and independently directed into the furnace by tilting at least one of the nozzles away from the longitudinal axis of the coal delivery pipe, thereby establishing an ignition stabilizing pocket in the locally low pressure zone created between the spread apart coal-air streams.

Abstract: METHOD OF FLASH BUTT WELDING         Abstract of the Disclosure Work pieces to be joined together by the flask butt weld-ing method are brought together, fused at a preset no-load voltage, and upset.  The invention consists in that the amount of the upsetting is set within from 1.2 to 3.0 of the amount of the maximum gap between the work pieces being welded together, which gap forms in the course of fusing the end faces of the work pieces, the maximum gap being determined from the follow-ing relation:                       .DELTA.max = f(Uo, .delta. ), where: .DELTA.max = maximum gap:          Uo = no-load voltage; .delta.  = thickness of the work pieces being welded together.    The method of the invention may be employed to advantage in constructing pipeline, welding together out-of-measure semifinshed sections in metal rolling, and fabricating various metal structures from rolled section.  Empirical formulas to determine the maximum gap for work pieces of various thicknesses are presented.
