Description
【発明の詳細な説明】 本発明は石炭の自然発火監視方法に関するものである。[Detailed description of the invention] The present invention relates to a method for monitoring spontaneous combustion of coal.
近年における石油の供給不安にもとづき、従来主として
用いられている石油焚火力発電所に代って、石炭焚火力
発電所が見直されつつあり、既にその一部は建設を終了
して稼動を開始している。Due to concerns about oil supply in recent years, coal-fired power plants are being reconsidered in place of the oil-fired power plants that have traditionally been used, and some of them have already completed construction and begun operation. ing.
ところでこの場合使用される石炭としては価額二が安価
であり供給が安定している中国、南アフリカ、豪州など
の海外炭が多く使用されているが、その輸入コストの低
下などから１回の輸入扱い量は極めて多く、従ってまた
貯炭量も５０〜５０万トンと従来のそれの２〜５倍にも
及ぶ大きなものとなる。By the way, the coal used in this case is often imported from countries such as China, South Africa, and Australia, where the price is cheap and the supply is stable, but due to lower import costs, it is treated as a single import. The amount of coal stored is extremely large, and therefore the amount of stored coal is 500,000 to 500,000 tons, which is two to five times that of conventional coal.

多数の温度センサーを用い、しかもセンサー相互の間隔
と狭くして測定しない限り、適確な高温発生部の位置を
検出することが困難である。For this reason, large machines such as coal unloading machines have begun to be adopted in place of conventional bulldozers in order to save labor and improve efficiency in loading and unloading coal. It is not possible to compress the coal as in the conventional method, and natural coal storage with large air circulation gaps is required. As a result, the coal self-heats due to oxidation due to oxygen content in the air, and the chance of spontaneous ignition due to the rise in temperature inside the coal storage due to this is greater than in compressed stacking. Therefore, as a method to monitor the possibility of spontaneous combustion, a method has been proposed in which, for example, thermocouple temperature sensors or semiconductor temperature sensors are randomly inserted into coal storage piles to directly measure points where the temperature is rising. There is. However, the size of natural coal storage piles is unprecedented due to the increase in handling volume as described above, for example, 45 m wide, 90 m long, and 16 m high (20,000 tons of coal). case) becomes even bigger. On the other hand, the high temperature generating part is not only small compared to the overall size, but also moves depending on weather conditions such as wind direction and wind speed. Therefore, it is difficult to accurately detect the position of a high temperature generating part unless a large number of temperature sensors (up to several dozen) are used and the distance between the sensors is narrowed.

も云える方法が依然として採用されている状態であり、
その改善が強く要望されている。Furthermore, with this method, not only do the temperature sensors have to be removed when the coal storage pile is taken down by discharging, but also it is extremely complicated and time-consuming to insert a large number of temperature sensors each time a new coal storage pile is formed. Since there are many temperature sensors, the data processing is also complicated. As a result, even if this method is applicable during testing, it cannot be applied in terms of workability or economy. Therefore, at present, primitive methods such as visual monitoring by workers handling coal storage piles and other methods that rely on experience and intuition are used to predict natural sludge fires in advance and cool high-temperature areas with water sprinkling. The method that can be said to be
There is a strong demand for improvement.

て温度分布の測定を容易とすることが可能となった。The present invention provides a method for monitoring spontaneous combustion, which can easily and accurately detect high-temperature areas to prevent spontaneous combustion even in the case of large-scale coal storage piles such as those described above. This was in response to strong demand. Next, we will explain the details using drawings.The recent development of technology uses an infrared camera and a radiation thermometer to measure the surface temperature of various objects at temperature intervals of about 0.5°C. It has become possible to clearly display the image as an image, and to process the isothermal portions according to color, making it easier to measure the temperature distribution.

りうろことを着想したものである。As a result of experimental research, the present invention has revealed that by applying this technology, it is possible to accurately monitor the temperature distribution on the surface of a coal storage pile. After fully understanding from
By inserting a temperature sensor into a detected high-temperature area, the internal temperature can be measured quickly and reliably without using multiple temperature sensors as described above, and based on this, preventive measures can be taken by cooling the high-temperature area with water spray. It was inspired by the concept of scales.

８０〜９０’Ｃ以上である。On the other hand, according to research 2 of the present inventor, the temperature curve of the high temperature part in the coal storage pile before spontaneous ignition is as shown in Figure 1. It consists of a period of constant temperature maintenance during which radiation is balanced, and it has been revealed that during this period of constant temperature maintenance, the equilibrium flexibility of heat generation and heat dissipation is disrupted for some reason, leading to spontaneous combustion. On the other hand, when we cut down a coal pile that had spontaneously ignited in an experiment and observed the inside of the pile, we found that the area where the spontaneous ignition occurred was extremely dry. Moreover, when comparing and measuring the length of the constant temperature maintenance period until ignition of coal storage piles indoors and outdoors,
Rainwater (A) It has been confirmed that indoor coal storage piles are shorter than outdoor ones.
The state of the moisture inside the coal storage pile, such as drying of the moisture in the coal storage pile, for example, the adhering moisture on the coal surface, which is referred to as moisture in this field, and the contained moisture in the coal pores, which is referred to as moisture in this field.
It has been revealed that the state of total moisture contained in deposited coal (intrinsic moisture) is a direct cause of spontaneous combustion. In other words, if heat dissipation continues without moisture being replenished by rainwater, etc., the inside of the coal storage pile will dry out and the moisture content will decrease, and the oxidation heat that was dissipated as a source of moisture will accumulate, causing rapid The ignition conditions vary depending on the type of coal, but for example, the adhering moisture is 1% or less, the total moisture is 5% or less, and the temperature is 80 to 90°C or more. It is.

なされたものである。From the above, the present invention is capable of measuring the temperature of the high-temperature area confirmed by the image showing the temperature distribution described above, and measuring the moisture content of the accumulated coal using a moisture sensor. This idea was created based on the idea that spontaneous combustion could be predicted and monitored more accurately by using a moisture sensor to measure the moisture state of coal.
