Enameled wire oven

摘要

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.
