INDUSTRIAL FURNACE WITH IMPROVED HEAT TRANSFER |
摘要 |
An improved industrial furnace employing a new and unique heat transfer arrangement is disclosed. The furnace is a closed end cylindrical chamber with a circular, concentrically positioned plate dividing one side of the furnace into a fan chamber containing a fan and the other side of the furnace into a heat treat chamber containing the work. The plate has a central under-pressure opening and its outer circular edge is spaced from the cylindrical wall to define an annular space which is non-orificing. Fan rotation in the fan chamber produces an annulus of wind mass swirling at high circumferential speed which axially travels through the non-orificing space towards the closed end of the heat treat chamber at slow speed. Heating elements extend through the non-orificing space into the heat transfer chamber and are constantly impinged by the swirling annulus wind mass to effect good heat transfer therewith. The under-pressure opening causes the heated wind to contact the work before it is drawn into the under-pressure opening for recirculation. An incineration track is provided in the furnace insulation for incinerating the furnace flue products while also heating the wind mass.
