Abstract:
A method of preventing a jamming condition of one or both of feed and compression auger-screws in a compression device for feeding a waste material to a reactor, comprising the steps of:(a) providing a logic means operably connected to a drive means for independently rotating the feed and compression auger-screws; (b) detecting a torque-resistance in one or both of the feed and compression auger-screws from the drive means; (c) comparing the value of the detected torque-resistance with a preset value; (d) alerting an operator if the detected torque-resistance value is higher than a preset value; (e) varying a normal rotational speed and direction of one or both of the feed and compression auger-screws; (f) monitoring the torque-resistance of the feed and compression auger-screws until the torque-resistance in both is lower than the preset value; and (g) returning the rotational speed to normal upon reaching the condition in step (f).
