Abstract

PURPOSE:To enable to effect a correct refuse discharging by a method wherein two sets of time constant circuits having different time constants which are connected to a supersonic wave transmitting and receiving instrument are provided and the refuse level signals from these circuits are outputted under selecting refuse throwing time and refuse discharging time. CONSTITUTION:The supersonic wave transmitting and receiving instrument 5 is provided above the refuse throwing hopper of the refuse incinerating furnace to receive the supersonic wave sent toward the accumulated refuse. The received supersonic signal is converted into an electric signal by a convertor 6 and is outputted into the time constant circuits 7, 8 while either one of the outputs of these time constant circuits 7, 8 is switched to the output terminal 15 of the level meter automatically by switching a change-over switch 9 by the relay 13 of a controller 10. When the refuse is thrown into the hopper, it is switched to the side of the circuit 7 having a smaller time constant or a quick response, on the other hand, when the refuse is discharged, it is switched to the side of the circuit 8 having a larger time constant or the slow response. The controller 10 controls the relay 13 in accordance with the result of comparison between the differential signal of the outputs of both circuits 7, 8 and a preset value.
