Description
ハインリヒ・ランツ・アクト・ゲスによるドイツ特許出願DE−444588「ダンプユーバヒッツアー」(蒸気過熱器)にも非円形管が記載されている。しかし、この実施形態では、エネルギー吸収により蒸気の温度と容積が増加するが、管内流速を一定に保ちながら管の長さに渡って管の断面が変化する。これはボイラー内をジグザグに走る長い管の場合に特に関係する。管を何度も平たくロールして管の断面を単純に変化させる提案された方法の結果で非円形が形成される。本発明では煙道ガス側の流れを最適化する明白な目的が非円形である。これは2つの管寄せ間に取り付けられた比較的短い直管にも(これだけではないが)適用できる。
非円形管による管群で剛性を異ならせる別の方法として、目的に応じて特別に設計した剛性付与および補強によって管の固有振動数に影響を与えることも可能である。
また、管を非円形とし、固有振動数を作動方向に依存させ、選択された作動方向は管の縦方向に垂直な方向とする方法も好ましいものである。
また、好ましい実施形態によれば、発明は少なくとも2つのセクションの前方にシールド管または蒸発管が配置された熱交換器に関係する。
図1に廃棄物焼却設備の概略図を示す。煙道ガスは第1室に導かれて垂直に上昇し、次に第2室に移り煙道ガスは下方に導かれ、さらに第3室に移る。第1室は公知の(図示しない)板状溶接壁でもっぱら作られる。
さらに好ましい変形として、図3,4および5に示すように、OVO管41,30は多少楕円形状にし、その短径は煙道ガスの流れSの方向に直角に向ける。これで、煙道ガスに含まれる飛灰によって起こされる侵食に基づく管41の磨耗が減少する。OVO管を振動させることによって(例えば、管端部が取り付けられて機械式あるいは空気式ハンマ69を有する管寄せ61,62,63(図5参照)を打つことで)図4に示すOVOの管30上の飛灰の堆積物34を除去する従来技術の方法は、OVO管の特別の固有振動数を与えることでかなり改善できる。なお、管30の非円形に起因する剛性の違いに基づき、異なる方向71,72においてこの固有振動数は異なる。管寄せ61をこの固有振動数で振動させて、堆積した飛灰34は制御された方法で除去することができる。管の固有振動数を互いに(すべて同一に)適切に調節することによって、限定されたエネルギー入力で最大の結果が得られる。飛灰堆積物の付着量が違いすぎるためにこれが困難なときは、すべてのOVO管に異なる振動数(振動の異なる方向71,72でさらに異なる)を与えて、個々の管30が共振状態となることを可能とする。したがって、非円形管が管を共振状態にもっていける特別に選択された固有振動数を有するシステムが好ましい。さらに、振動パターンを決定するため測定計器73を備えることが好ましい。
本願で使用する用語「非円形」は、少なくとも管の長さの一部に渡って、非円形管のように見える補強管である実質的な円形管にも同様に、また限定することなく適用される。
