| Abstract: | This design adopts theory of closed loop control, and makes use of controllable silicon technology to implement whirlwind warm-up device's digital control,and controls whirlwind device though turn-on angle of controllable silicon which are changed by the feedback of voltage. So heat energy is used absolutely by cement rotatory kiln, and reduce exhaust gas which is let by cement rotatory kiln.The validity of design was proved by simulation experiment and locale debugging. |
