本発明は、金属板外被を有する熱交換器特に高炉設備の
熱風炉用の保護袋ｊｒ１に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a protective bag jr1 for a heat exchanger having a metal plate jacket, particularly for a hot blast furnace of blast furnace equipment.
本発明の課顯は、゛このような熱交換器において金属板
外被の応力腐食割れをできるだけ回避することである。An object of the present invention is to avoid stress corrosion cracking of the metal plate jacket in such a heat exchanger as much as possible.

発明による手段は、このような熱交換器の燃焼室および
蓄熱室に関するだけでなく、その後に接続されて高炉の
熱風環状管まで通ずる熱風木管にも関するものである。Here, the present invention takes advantage of the new knowledge that climate-induced temperature differences on the outside of the metal plate jacket of a heat exchanger, such as a hot blast stove in a blast furnace installation, can cause undesirable stress corrosion cracking. The proposal of the invention makes it possible to avoid climatic influences that cause such temperature differences. However, the measures according to the invention concern not only the combustion chamber and the heat storage chamber of such a heat exchanger, but also the hot-air wood pipes connected afterwards and leading to the hot-air annular pipe of the blast furnace.
このような手段はＤｉ造に対して重要であるだ１）でな
く、特に連続操業において遮断できない設備部分の改心
に対しても重要である。Such measures are important not only for Di-building (1), but also for centering parts of equipment that cannot be shut off in continuous operation.
本発明による手段を実現するために、熱交換器を気候に
対する保護装置特に設備例えば高炉設備の他の部分の風
よけあるいは特別に設けられた風そらせ体に設けること
ができる。In order to realize the measure according to the invention, the heat exchanger can be provided in a climate protection device, in particular in a wind shield or a specially provided wind deflector of other parts of the installation, for example a blast furnace installation.
風そらせ体はなるべく熱交換器の近傍に設置されるか、
あるいは案内板あるいは保護板として熱交換器に取付け
られている。Is the wind deflector installed as close to the heat exchanger as possible?
Alternatively, it is attached to the heat exchanger as a guide plate or protection plate.
さらに熱交換器に雨よけを付属させることができる。Furthermore, a rain cover can be attached to the heat exchanger.
風そらせ体と雨よけが設けられている場合、これら両者
を熱交換器の建屋状改心部として構成することができる
。If a wind deflector and a rain screen are provided, both can be constructed as a building-like conversion part of the heat exchanger.

異なり、金属板外被温度の露点超過による応力腐食割れ
を回避するという課題をもっていない。In addition, wind deflectors and rain shields are preferably made from metal or plastic sheets. However, it is also possible to use inorganic or organic coatings for wind deflectors and rain protection. These protection means, unlike known insulation means, do not have the problem of avoiding stress corrosion cracking due to excess of the dew point of the metal plate jacket temperature.
最ＰＩＪから風、温度あるいは雨の影響が比較的少ない
ような地理的場所に熱交換器を設置することも可能であ
る。It is also possible to install the heat exchanger in a geographical location where there is relatively little wind, temperature, or rain influence from the highest PIJ.
