に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for controlling the operation of a waste incinerator, particularly a method for detecting the burnout point in the incinerator and controlling the combustion state of waste. be.

によってもごみ汚水の切れが違う。In general, incinerators that dry and incinerate waste such as waste wood, agricultural waste, urban waste, wastewater, sewage sludge, and raw sludge while moving it on a stoker, directly monitor the burning condition of the waste in the incinerator. Visually check or use industrial television (
IT, V) feeding rate of waste into the furnace while monitoring;
The stoker speed and combustion air were also controlled. However, waste delivered to incineration facilities is not uniform; for example, in a city, the waste may vary depending on the collection area, weather on the collection day, etc.
The composition, moisture content, and calorific value of garbage vary depending on the season. Furthermore, the amount of waste and sewage drained differs depending on how long it stays in the focus after being brought in.
したがって、性状が不均一で変化のはげしいごみを高負

。Therefore, in order to incinerate waste whose properties are uneven and change rapidly under high load, and to minimize the amount of unburned matter (loss by burning) in the incineration residue (ash), the temperature inside the furnace must be monitored. The waste feed rate, speed, etc. should be adjusted so that the operator can monitor the combustion status of the waste in the furnace directly through the monitoring window or via a monitor TV to maintain the burnout point at an appropriate position. It controlled the force speed, amount of drying/combustion air, etc.
近年、計測技術の進歩により各種の燃え切り点の検知方

方法などである。In recent years, with advances in measurement technology, various burnout point detection methods and automatic driving control methods incorporating these methods have been proposed. For example, there are a method using a photoelectric element, a method using the brightness of an ITV cathode ray tube, a method of detecting the combustion start point from the temperature of the dust on the stoker, a method of detecting the combustion start point based on the temperature of the gas in the furnace, etc.

る必要があった。However, with the ITv image processing method, the mounting position of the monitor television camera (usually in the post-combustion zone or in front of the furnace) is far from the position where the burnout point should be set, so although the overall burnout condition can be determined, the burnout point cannot be accurately determined. In addition, the scanning mechanism to change the camera angle, image processing, etc. are expensive. In addition, with methods that use photoelectric elements or thermometers, the combustion status at a measurement location can be determined from the presence or absence of flame or the temperature level at that location, but in order to locate the burnout point, it is necessary to It was necessary to install a large number of detectors (photoelectric elements or thermometers).
本発明は、焼却炉内の廃棄物の燃え切り点を容易に精度

とするものである。The present invention easily and accurately detects the burnout point of waste in an incinerator, controls the combustion state in the incinerator to maintain this burnout point at a set position, and constantly adapts to changes in the properties of the waste. The purpose is to provide a method that can perform ideal incineration.

ものである。The present invention provides an incinerator that incinerates waste while moving it on a stoker, in which a burnout point for the waste is set, and fire grates are provided on the upstream and downstream sides of the waste flow direction from the burnout point. Temperature detectors are provided, a burnout point is calculated based on the relative values of the output signals of these temperature detectors, and the combustion state of the waste is controlled so that the calculated value maintains the burnout set point. The present invention is characterized in that the relative value is adjusted.

れをまとめると、次のようになる。In other words, the present invention is characterized by the fact that the temperature of the grate constituting the stoker changes near the burn-out point, and in particular, the composition of the waste, the amount of moisture it contains, the amount of heat generated, etc. condition, deposit thickness on the grate, combustion air amount and temperature,
This study focuses on the fact that the same grate temperature can vary greatly even if the burn-out point υ is at the same location but on different dates and times because the amount of radiant heat received from the furnace temperature changes. More specifically, when focusing on the grate temperatures at two arbitrary points before and after the burnout point, there is an extremely high correlation between the relative values of the temperatures at these two points and the burnout point. That is, in FIG. 1, the temperature of the grate temperature detector 7 on the upstream side of the waste flow F across the point (or range) at which the burnout point P is to be set is T1, and the grate temperature on the downstream side is T1. Assuming that the temperature of the detector 8 is T2, when the actual burnout point P moves upstream, T1 increases and T2 decreases. On the contrary, burnout point P
When moves downstream, T1 falls and T2 rises. This can be summarized as follows.
一第１図中、Ｂは燃焼している廃棄物、Ｃは燃焼の終了

整すればよいことに基づいて構成されている。The absolute values of T1 and T2 at the burnout point are not necessarily constant, but the relative value of T+ and T2, for example, T1/T2, varies depending on the amount of incineration, the thickness of the pile, the temperature inside the furnace, etc. Therefore, in the present invention, in order to return the moved burning edge point P to the set range, the grate temperature TI/T2 is adjusted by controlling various combustion states in the furnace. It is structured based on good things.

The figure shows an example in which the present invention is applied to the combustion power of a stepped incinerator for municipal waste. The waste supplied into the furnace I by the garbage input hopper 1 and the input busher 2 is transferred to a drying stoker 3, a first combustion stoker 4, and a second combustion stoker 4'.
, are incinerated while being sequentially transferred through the afterburning stoker 5. A is drying waste, B is burning waste-1
C is the incineration residue after combustion. Waste is burned on the surface even in a dry stoker because the moisture on the surface layer rapidly evaporates due to the radiation inside the furnace, but it is mainly burnt in combustion stokers 4 and 4.
', and in the after-combustion stoker 5, the unburned matter in the accumulated incineration residue C is left and completely incinerated by combustion.

The temperature of the grate at the end of the combustion stoker 4' is measured by temperature detectors 7 and 8, respectively.Since the purpose is to measure the metal temperature of the grate, the temperature detector is installed in the combustion air supply box (wind box). ) It can be installed inside Party B.

に変更する。The temperature detector 7.8 should be installed so as to sandwich the set point (or set range) of the burnout point P, and if there is a possibility that the end of the drying stoker 6 and the post-combustion stoker 5 are also burnt out, the range should be set. Also include. However, if the setting range is too wide, the detection accuracy of the burnout point P will be poor, so a temperature detector 7' is attached between temperature detectors 7 and 8 as shown in Figure 3. It is also possible to change the combination of temperature detectors to be compared as the point P moves. For example, the first 7
If the combination of 7' and 7' is detected, and the calculation result shows that the position has moved downstream by 7', the combination is automatically changed to 7' and 8.

ある。Furthermore, since the maximum value of the grate temperature is often present at the burnout point or around 2 to 3 m upstream from it, the maximum temperature may be used as a complementary factor. Furthermore, if the distance between the temperature detectors to be compared is too narrow, the difference in temperature between the rain detectors will be small and the error will increase, so the distance should be at least about 2tn.

It was in good agreement with Fu M/c JK, and we were able to detect the burnout point P with the same accuracy as in the early evening months.

The burnout point may be calculated using the relative value of the average value of the output signal of ~T6 and the same average value of the plurality of temperature detectors T7 to T12 at the terminal end, and in this case, the burnout point P Detection accuracy is improved.

The incinerator is automatically operated by controlling at least one of the waste supply linkage, the stoker speed, and the amount of combustion air so that the burnout position is corrected to the set point. Alternatively, the burnout point can be displayed on a graphic panel in the incinerator central monitoring room, and the settings of each of the above operating factors can be changed manually.

た理想的な焼却を行うことができる。As described above, according to the present invention, compared to the conventional method using photoelectric elements or the method of processing the brightness of an ITV cathode ray tube, the temperature inside the furnace can be improved by installing an inexpensive temperature detector such as a thermocouple thermometer. It is possible to accurately detect the point at which waste burns out. Furthermore, the various methods that have already been proposed for detecting the burnout point using temperature sensors can only determine whether or not the waste at the location where the temperature sensor is installed has burned out; In order to know where the υ point is, it was necessary to install many temperature detectors at regular intervals in the flow direction of the waste, but in the present invention, the burnout point can be set. Fluctuations in the burnout point can be continuously and accurately determined by detecting the temperature at two points above and below the set point. Furthermore, by inputting the burnout point detection signal to the control equipment for various operating factors displayed on a panel in the control room, it is possible to automate the operation control of the waste incinerator, making it possible to constantly respond to changes in the properties of waste. Ideal incineration can be performed.
