Abstract

PURPOSE: To accomplish automatic operation of the hopper such as a clinker hopper disposed at the bottom of a furnace, by providing a transmitter and a receiver at a lower portion of the hopper in the manner that they face toward each other, and starting ash discharging operation when a signal from the transmitter is received by the receiver.

CONSTITUTION: The clinker hopper disposed at the bottom of the furnace is filled with water to a reference level 11, and ash 10 accumulated inside the side wall 1 of the hopper is carried into a clinker crusher 5 via a through-gate 2 opened and closed by a cylinder 4 and an enclosure 3. In the crusher 5, the ash is crushed into pieces, which are then drawn out by a jet pump 7 and carried via transport pipe 6 to an ash discharging station. In the above arrangement, a transmitter 12 is fixed to the side wall 1 at a portion thereof facing the opening 9 which is opened and closed by the gate 2, and a receiver 13 is fixed to the inner wall of the enclosure 3 in the manner that it face the transmitter 12. In discharging ash, it is known that the discharging of ash has been completed, when a signal from the transmitter 12 is received by the receiver 13.
