      A Air curtain in Entrance Air atmosphere to prevent the air outside getting inside.
      B Venturi Exhaust Gas Inlet Venturi Exhaust gas inlet, can adjust the exhaust volume of two stacks.
      C Firing gas inlet Used for fresh air supplement.
      D Air curtain in Exit Air atmosphere to prevent the air outside getting inside.
      The actual gas flow of each pipe can be displayed by flowmeters


      3 . 3    The Design of Temperature Control System
    30. Temperature Measuring: use K type thermocouple independent measuring and control on the temperature control point of each zone.   
    31. Temperature Control: use of Intelligent temperature controller to control, with PID parameter auto tuning, high temperature upper limit alarm, thermocouple failure and other protective alarm functions.
    32. Heating Control System: after starting hot air circulation, the heating can be turned on. for the heating control, grouped supply the electricity by some alternating current contacts  to  reduce the instantaneous current impact to the electric fence caused by the equipment.
    33. Control Mode:Solid State relay zero cross trigger mode .
    34. Over Temperature Alarm: whe n over temperature occurred  in some zones, over temperature alarm system in corresponding zones immediately send audible and visual alarm signal and meanwhile the heating of this zone is cut off, the buzzer sounds alarm.

    35. 3. 3   Drive System Design
      3.3.1 Drive Control uses the VFD  control the speed by gear box. T he speed is adjustable continually.
      3.3.2 Belt conveyor device: to drive the driving and driven wheel through chain and sprocket wheel, and then generate the friction force by driving wheel and the belt drive the belt running. There is a belt deviation guide device on the both sides at the entrance and exit.
      3.4  Industrial Computer system(reserved)
      This furnace is not equipped with industrial computer system at this time, the position for installing the computer system is reserved for updating in near future.
