A recirculating oven having dual air plenum chambers each controlled by an individual blower receiving air and oxidized gases from a burner tube intermediate the plenums. The gases leaving the burner tube are drawn by the blowers into the respective plenum and enter a pair of evaporation zone modules at the bottom of the plenums and a curing zone module at the top are fed into a pair of wire work chambers, both air streams mixing between the zones and return with volatile fumes through a return module to a burner mounted in the upper portion of the burner tube which receives the mixture in a swirling fashion from a vortex generator between the tube and burner. The burner tube is mounted within a burner tube housing partitioned so that the volatile fumes returning to the burner are maintained separately from the oxidized gases and air exiting from the burner tube. The wire work chambers are formed in a recess between oven access doors and the oven box and can be increased for larger size wires by positioning inserts between the door and the oven.
An oven for drying and curing coated wire and the like comprising, an outer housing including a plurality of structural members fastened together into a substantially rectangular frame and having exterior surface means fastened to the outer portions of said members, a pair of vertically elongated air chambers disposed within said outer housing spaced from each other, each air chamber including an upstanding wall means, a vertically elongated burner tube housing disposed within a medial portion of said outer housing intermediate said air chambers, a partition disposed across said burner tube housing for dividing said burner tube housing into upper and lower zones, a vertically elongated burner tube disposed within and spaced from said burner tube housing, said burner tube extending through said partition in substantially sealed disposition therewith for communicating the upper zone with the lower zone, said burner tube including a plurality of inlet openings at the upper end and an outlet opening at the lower end, a burner having inlet openings and flame generating means disposed within said burner tube adjacent the upper end, each of said air chambers having separate blower means including an inlet communicating with the lower zone of said burner tube housing and an outlet communicating with the respective air chamber for circulating hot air from the lower zone of said burner tube housing into the air chambers, a door means removably secured to said outer housing in spaced relation with each of said wall means for defining a pair of work chambers therebetween for receiving wire fed vertically upwardly from a wire inlet through each work chamber to a wire outlet upper and lower supply conduit means within each of said air chambers communicating the interior of each air chamber with a respective upper and lower portion of one of said work chambers, and a return conduit intermediate each pair of upper and lower supply conduits communicating each work chamber with said upper zone of said tube housing.
