2. Description of the Related Art In the process of producing coke from coal in a carbonization chamber of a coke oven, the coal expansion pressure acting on the furnace wall of the coke oven due to the expansion of the coal damages the furnace wall of the coke oven and makes it impossible to operate. Expansion pressure management is an important issue in furnace body management, as the coke oven may be forced to shut down.

In recent years, attention has not been paid to inflation pressure in Japan. However, in the future, the aging of the furnace body will progress and the strength of the furnace body will decrease, and the introduction of coal pretreatment technologies such as the humidifying coal method and the preheating coal method will increase the coal charge density in the coking chamber, and Is increasing, so attention to the inflation pressure is needed.

It is known that the cause of the expansion pressure is the gas pressure in the coal bed in the softened and molten state. In a small test coke oven, the gas pressure in the softened molten layer can be easily and accurately measured, and the test coke oven is capable of directly measuring the expansion pressure acting on the oven wall with one wall movable. Many researchers found that there is a correlation between the maximum inflation pressure when the coal layers softened and melted in the center of the coking chamber and the gas pressure peak value in the coal layer in the softened and molten state at the same time.

However, an actual coke oven has a height of several meters,
The length is as long as several tens of meters, and the variation in the state of coal filling in the furnace height direction and the furnace length direction is extremely large. For example, when viewed in the furnace height direction, since the charging density immediately below the coal charging inlet is higher than that between the coal charging inlets, it is considered that the expansion pressure is also high. As described above, it is presumed that there is a distribution of the expansion pressure in the furnace height and the furnace length direction in the actual furnace.

[0006] Since the expansion pressure is a force applied to the furnace wall and cannot be directly measured in an actual coke oven, gas pressure measurement in a softened molten coal layer which is a cause of the expansion pressure has been attempted in an actual furnace.
Conventional gas pressure measurement methods in actual furnaces include:
It is measured by inserting a metal tube having an inner diameter of several mm with a slit at the tip into the furnace from the coal loading inlet or the furnace lid. For example, Latshaw et al. (GM Lat.

In y), the probe is inserted horizontally from the furnace lid and vertically from the charging port to measure the gas pressure. The probe inserted from the furnace lid has an inner diameter of 9.525 mm and a length of 3 m.
And 3.175mm diameter with 6m steel pipe
Are formed at upper and lower sides at intervals of 25.4 mm from the probe tip. On the other hand, the probe to be inserted from the inlet is a steel pipe with an inner diameter of 25.4 mm, length of 1.5, 2.7 and 3.9 m, and holes of 3.175 mm in diameter at right and left 75.4 mm apart from the probe tip. (Probes are inserted so that the holes are lined up in the furnace length direction). However, in such a method, firstly, the probe insertion position cannot be fixed clearly, secondly, coal is clogged in the probe in the process of inserting the probe into the furnace, and thirdly, the size of the probe Is too large compared to the thickness of the softened molten layer to be measured, the reproducibility is poor, and reliable data is not available, so the expansion pressure distribution of the actual coke oven cannot be accurately grasped. It is the current situation.

Here, the pressure detecting probe has a tube diameter sufficiently smaller than the thickness of the softened molten layer to be measured. The probe may be used alone or may be accompanied by a detecting end of a temperature measuring means. The bent probe is put out of the pipe at the end of the open metal pipe, or the probe is turned back at the end of the metal pipe. Preferably, immediately after charging, insert the probe into an arbitrary position in the actual coke oven using the furnace lid as a guide from the furnace lid with a hole made of a probe with a metal pipe, and then pull out the metal pipe.
By determining the probe position and preventing coal clogging during the probe insertion process, the gas pressure in the softened molten coal layer equal to the expansion pressure acting on the coke oven furnace wall, or the gas pressure distribution in each part in the furnace, is accurately determined. It is to be measured.

First, the probe insertion position is not fixed for each experiment. Since the expansion pressure shows the maximum value when the softened molten layer meets at the center of the carbonization chamber,
Normally, gas pressure measurement is performed when the softened and molten layers meet at the center of the furnace width of the coking chamber. However, in an actual coke oven, there are several meters from the coal charging inlet or the furnace lid to the measurement point, and it is necessary to insert a few meters probe into the furnace. For this reason, it is extremely difficult to accurately position the gas pressure detecting end position at the center of the furnace in the furnace width direction, which is the measurement point, and it is usually shifted to the left or right. In addition, a method of fixing the probe using a fixing jig in the carbonization chamber in an empty kiln state in advance is also conceivable, but the fixing jig becomes a resistance when charging coal, causing a change in the bulk density of the coal, and a steady state during the steady state. Gas pressure cannot be obtained. If the gas pressure deviates slightly from the center of the coking chamber, the gas pressure value will differ greatly, and the gas pressure during steady state cannot be measured due to the change in coal bulk density. In addition, a method is required that can measure the gas pressure at the steady bulk coal density. Second, coal is clogged in the probe during the process of inserting the probe into the furnace. Since the slit at the tip of the probe is as narrow as about 1 mm, little attention has been paid to this point in the past. However, the inventor has confirmed that coal enters the probe in the process of being inserted into the furnace.
If the coal that has entered when the softened molten layer has reached the probe tip position is simultaneously softened and melted, the gas pressure in the softened molten layer apparently becomes higher than the actual value. Also, if the coal inside the probe softens and solidifies before the softened molten layer reaches the probe tip position, the probe will be blocked by the solidified coke, so when the softened molten layer reaches the probe position, the gas pressure will actually Is detected lower than the value of. Therefore, it is necessary to make the probe structure such that coal does not enter.

Third, the conventionally used probe is too large. Conventionally, the probe was required to have a certain thickness in order to be inserted into the coal seam, but as a result, a probe having the same thickness as that of the softened molten layer was used. This caused a remarkably large disturbance. In order to solve this problem, it is necessary to use a probe as small as possible.

【0013】この知見に基づき、発明者は以下に示す具

In the present invention, a probe having a pipe diameter sufficiently smaller than the thickness of the softened molten layer to be measured is used as the gas pressure probe. Softened molten layer thickness is 2-3mm near the wall
Therefore, the inner diameter of the probe must be 1 mm or less, which is smaller than the thickness of the softened molten layer, and the outer diameter must be at most 2 mm or less so as not to affect the process of forming the softened molten layer. If necessary, the detection end of the temperature measuring means having a diameter of 1 mm or less is fixed to the probe with a wire. The thickness of the detection end of the temperature measuring means is limited by the thickness of the softened molten layer and must be 1 mm or less.
