給できず、燃焼が不安定になることがあった。In recent years, refuse incinerators have been operated with an emphasis on improving combustion stability from the viewpoint of preventing the generation of dioxins. However, when the pusher 23 retreats, the dust does not fall into the retreat gap 24 when the pusher 23 retreats, so that there is a problem that a predetermined amount of dust cannot be sent out by the next movement of the pusher 23. In such a case, even if the cycle speed of the pusher 23 is increased, it is not possible to cope with the situation, and it is not possible to supply a predetermined amount of refuse.

により操作される。The pushers 3A and 3B are driven by hydraulic pressure supplied from a hydraulic pump 5 to drive cylinders 4A and 4B via a lower switching valve 6A and a lower switching valve 6B, respectively. As a result, an operation signal is output to each of the lower switching valve 6A and the lower switching valve 6B, and drive control is performed. The pusher operation control device 7 is manually operated by receiving a setting signal from the operation panel 9 and operated manually. Also, the incinerator 2 is controlled based on a detection signal from a dust supply detection device and sensors 10 for monitoring the combustion state in the furnace. It is operated by a signal from the combustion control device 8 which performs the combustion control of.

退限Ａまで後退移動される(STEP.3)。Next, the operation of the waste supply apparatus 1 will be described with reference to FIGS. First, the lower drive cylinder 4A is extended, the lower pusher 3A is protruded from the retreat limit A to the protruding limit B, and the front waste is extruded into the incinerator 2 (STEP.1). At this time, the lower pusher 3A is moved to the projecting limit B by a sensor or the like built in the drive cylinder 4A.
(STEP.2). When the protrusion limit stop time T1 set in the timer elapses, the lower drive cylinder 4A is contracted, and the lower pusher 3A is moved backward from the protrusion limit B to the retreat limit A (STEP.3).

より十分な量のごみが焼却炉２に送り出される。Here, a first standby time W1 for lowering the dust above and below the lower pusher 3A and sufficiently stabilizing the waste is set by a timer, and the elapse of the first standby time W1 is confirmed (STEP. 4) After that, the upper drive cylinder 4B is extended, the upper pusher 3B is moved from the retreat limit a to the protrusion limit b, and the dust on the lower pusher 3A is pushed forward (STEP.5). At this time, the upper pusher 3 is detected by a sensor or the like built in the upper drive cylinder 4B.
It is confirmed that B is at the protrusion limit b (STEP.6). As a result, even if sufficient debris does not descend in the front gap generated when the lower pusher 3A retreats, the gap is filled with the debris pushed out by the upper pusher 3B, so that the next lower pusher 3A protrudes and moves. Thus, a sufficient amount of waste is sent to the incinerator 2.

Further, it is confirmed that a second waiting time W2, which is a falling waiting time set in a timer, elapses (STEP.8) for the dust pushed out by the lower pusher 3A to drop and fill the gap (STEP.8). Returning to step 1, these operations are repeated.

W2 is controlled. In other words, if the operator visually determines the combustion state of the incinerator 2 or monitors the instruments, the increase or decrease in the amount of refuse is determined and the refuse quality is determined to be low, and the refuse quality is low. The first and the first through the pusher operation control device 7 by the board 7
The second standby times W1 and W2 are controlled so as to extend the second waiting times W2 and W2, respectively, so as to secure enough time for the dust to be sufficiently lowered. Conversely, in the case of high compressibility in which the quality of the waste is likely to decrease, the first and second standby times W1 and W2 are shortened to control the waste so as not to supply more waste than necessary.

The incinerator 2 is operated by controlling the operating state of the incinerator 2, and the pusher operation control device 5 is operated based on the output signal from the combustion control device 8. That is, when it is determined that the waste supply amount is smaller than the target value, the first and second waiting times W1 and W2 are extended, and when it is determined that the waste supply amount is larger than the target value. Is the first
The second standby times W1 and W2 are automatically controlled so as to be shortened. Of course, the control panel 7 and the combustion control device 8 allow the upper and lower pushers 3A, 3A as required.
The cycle time S of B and the retraction strokes L1 and L2 are also controlled, or the operation of the upper pusher 3B is stopped.

However, a sufficient amount of dust can be reliably pushed out and stably supplied by the lower pusher 3A.

And the stable combustion of the incinerator 2 can be realized. Thereby, generation of dioxin can be suppressed, and generation of clinker due to abnormal combustion and burning of stoker can be prevented. Further, the number of times the furnace is stopped due to these troubles can be reduced, which can contribute to the suppression of the generation of pollutants such as dioxin which is likely to be generated at the time of startup.
