  • Modular furnace system
    Patent number: 6394794
    Abstract: A modular furnace is fabricated from at least one module having a frame, a removable cover mounted to the frame, exterior cover panels on the frame, and an insulated case fastened to the interior of the module. A conveyor assembly extends through the module. A plurality of process zones, such as heating and cooling zones, are disposed within the module. Field replaceable universal blower assemblies are associated with each process zone. The motor shaft in each blower assembly is provided with a sealed bearing in the motor housing. Insulation within each module is held in place by gas permeable fabric covering large vent openings in cover panels to allow oxygen to diffuse out of the insulation rapidly upon start up.
