この発明は、コークス炉炭化室壁面に付着したカーボン
を焼落として除去するコークス炉の操業方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a coke oven operating method for burning off and removing carbon adhering to the wall surface of a coke oven carbonization chamber.
従来の技術

因となるほか、熱伝導率の低下等の原因となる。このた
め、定期的な除去作業が必要である。BACKGROUND ART - Carbon generated by decomposition of hydrocarbons during the process of carbonizing coal may adhere and grow to form a thick layer on the wall surface of the carbonization chamber of a coke furnace. If left unattended, this will cause an increase in extrusion resistance during coke extrusion, clogging, and a decrease in thermal conductivity. Therefore, periodic removal work is necessary.
従来の炭化室に付着したカーボンの除去方法としては、
当該炭化室を１サイクル空窯となし、上昇管天蓋並びに
上昇管と反対側の装炭口蓋を開放し、上昇管のドラフト

気を導入し、付着カーボンの焼落としを行なっている。The conventional method for removing carbon attached to the carbonization chamber is as follows:
The carbonization chamber is made into an empty kiln for one cycle, the riser pipe canopy and the charging port on the opposite side of the riser pipe are opened, and air is introduced from the open coal charging port on the opposite side of the riser pipe due to the draft effect of the riser pipe. The attached carbon is then burned off.
しかし、この方法は、長時間炭化室を学窓とするため、

ましくないといわれている。However, this method uses the carbonization chamber as a window for a long time, so
Not only did the heat of carbonization increase, but production decreased during this period, and the coal charging port where air was introduced was cooled, causing damage due to spalling. This is said to be undesirable from the viewpoint of extending the life of the furnace body, since the expansion and contraction of the coking chamber wall bricks is large compared to the periodic fluctuation of the period.

が発生する。Another method, as described in Japanese Patent Publication No. 60-2348, is to use a spear-shaped jig with a sharp tip and manually push the coal out of the charging port on the furnace. However, with this method, the carbon layer completely peels off from the wall surface, impairing the sealing function of the furnace wall joint to the right of the carbon, and causing black smoke to be generated from the chimney due to gas leaking from the carbonization chamber to the combustion chamber.
又、この作業は、高熱重筋労働であり、しかも、炭化室
天井部や装炭口間の壁面上部に付着するカーボンは、炉
上からは死角となるので、突き落とし作業が困難である
。Further, this work requires high heat and heavy physical labor, and carbon adhering to the ceiling of the coking chamber and the upper part of the wall between the coal loading ports becomes a blind spot from above the furnace, so it is difficult to push it off.

しかしこの方法は、炭化室の付着カーボン層厚測定や、

りでなく、設備費が高価となる欠点が有る。However, this method is difficult to measure the thickness of the deposited carbon layer in the carbonization chamber.
This method not only complicates operations such as setting the injection conditions of the injection nozzle, but also has the disadvantage that equipment costs are high.
発明の目的
前記のごとく、炭化室の付着カーボンの除去方法として

この発明は、かかる現状にかんがみ、コークス炉の操業
方法を一部変更するのみで、炉壁面に付着したカーボン
を簡単に除去する方法を提供づるものである。In view of the current situation, the present invention provides a method for easily removing carbon attached to the oven wall surface by only partially changing the operating method of the coke oven.

This is a method of operating a coke oven, characterized in that the coal loading port is in an open state from the closing to the charging of coal, and the outside air is introduced into the carbonization chamber to burn off adhering carbon.

炭を開始している。Normally, coke oven carburizing work is carried out after extrusion is completed.
After the front and machine side furnace covers are installed, the coal loading vehicle opens the cover of the coal loading port of the carbonization chamber after extrusion is completed, and coal charging starts immediately.

の装炭口の蓋を開放したのち、石炭塔へ受炭走行する。In the carburizing work in this invention, when extrusion is completed and the coke side and machinite furnace cover are installed, the carburizing car is used to load one or two carburizers on the opposite side of the riser pipe of the coking chamber after extrusion is completed. After opening the mouth lid, it travels to the coal tower to receive coal.

。この短時間の空窩状態は、窯出しのたび毎に実施する
こともできるし、付着カーボンの状況に応じて、数回の
窯出しで１回実施することもできる。For this reason, while the coal loading car is traveling to receive coal, the relevant carbonization chamber becomes empty, and outside air is introduced into the carbonization chamber from the open coal loading port due to the draft effect of the riser pipe, and the carbon adhering to the furnace wall is combusted. The carbon is burned off. This short-time void state can be carried out every time the kiln is taken out, or it can be carried out once every time the kiln is taken out, depending on the state of attached carbon.
さらに、装炭車の石炭塔への受炭走行は、通常４〜５分
間であり、１ザイクル空窯を実施する場合に比較して、
極めて短時間であり、開放した装炭口部が冷却されてス
ポーリング等の発生する心配もない。Furthermore, the coal loading car usually takes 4 to 5 minutes to receive the coal from the coal tower, compared to the case where one cycle empty kiln is carried out.
It takes an extremely short time, and there is no fear that the open coal charging port will be cooled and spalling will occur.
発明の図面に基く説明
以下にこの発明の具体例を示す図面に基いて、発明の詳
細な説明する。DESCRIPTION OF THE INVENTION Based on the Drawings Below, the invention will be described in detail based on the drawings showing specific examples of the invention.

ように操業されている。As shown in Figure 1 (a), in the conventional operating method, before the extrusion in the current extrusion kiln is completed, the charging of coal into the kiln that completed the previous extrusion is completed, and before the transfer to the next extrusion kiln. In the meantime, operations are being completed to complete the coal receiving run for coal loading into the current extrusion kiln.

によって、受炭走行の間、前回の押出し窯を空窩状態と
するのでおる。On the other hand, as shown in FIG. 1(b), the operating method of the present invention is such that charging of coal into the previous extrusion kiln is started only when extrusion in the current extrusion kiln is completed. After opening the cover of the coal charging port on the opposite side of the riser pipe,
A coal receiving run is performed to load coal into the previous extrusion kiln, thereby keeping the previous extrusion kiln in an empty state during the coal receiving run.
この受炭走行の間の一時的な空窩状態によって、約４〜

極めて少なく、スポーリングも殆ど発生しない。Depending on the temporary void state during this coal receiving run, approximately 4~
Outside air is introduced into the carbonization chamber through the opened coal charging port due to the draft effect of the riser for 5 minutes, and the attached carbon is burned and removed. Moreover, since this time is 4 to 5 minutes, the cooling of the furnace wall bricks near the open coal charging port is extremely small, and spalling hardly occurs.

され、炉壁面の付着カーボンが燃焼除去される。When the coal loading car completes its coal receiving run, it loads the previous extrusion kiln, and when it completes, it opens the cover of the coal loading port on the opposite side of the rising pipe of the current extrusion completed kiln, and then shifts to coal receiving run. It is. By repeating these operations, each extrusion kiln is temporarily maintained in a closed state while the coal loading car is traveling to receive coal, and carbon adhering to the furnace wall surface is burned and removed.

のみで、炉壁面に付着したカーボンを窯出し時に焼落と
しできるから、１サイクルの空間実施による乾留熱量の
増加、生産量の減少、空気導入部の過冷却よる炉壁煉瓦
のスポーリング等による損傷が防止できる効果を有する
。Effects of the Invention As mentioned above, the method of this invention can burn off the carbon adhering to the furnace wall surface at the time of exiting the kiln by only partially changing the operating method, increasing the amount of heat of carbonization and reducing the production amount by performing one cycle in space. This has the effect of preventing damage caused by spalling of furnace wall bricks due to overcooling of the air introduction section.
