Description

【０００１】
【発明の属する技術分野】
本発明は複合発電（コンバインドサイクル発電）プラントに用いられる排熱回収ボイラ（以下、ＨＲＳＧと称すことがある）に関し、特に排熱回収ボイラの熱交換器の伝熱管パネルの立て起こし方法と伝熱管パネルの立て起こし治具に関するものである。
【０００２】
【従来の技術】
ガスタービン複合発電プラントは石炭焚きボイラ等を用いる火力発電プラントに比較して熱効率が高く、燃料として主に天然ガスを用いるので硫黄酸化物及びばい塵の発生量が少ないため排ガスの浄化処理の負担が少なく、将来性の高い発電プラントとして注目されている。また複合発電プラントは負荷応答性に優れており、電力需要に応じて、その発電出力を急激に変えることができる高頻度起動停止運転（Ｄａｉｌｙ Ｓｔａｒｔ Ｄａｉｌｙ Ｓｔｏｐ）に適した発電方式としても注目されている。
【０００３】
複合発電プラントは、発電用ガスタービンと該ガスタービンの排ガスを用いて蒸気を発生させるＨＲＳＧと、該ＨＲＳＧで得られた蒸気を用いて発電を行う蒸気タービンを主要な構成機器とするプラントである。
【０００４】
図１に助燃バーナを内部に備えた横型ＨＲＳＧの概略構成図を示すが、ＨＲＳＧは水平方向にガスタービンからの排ガスＧが流れるガスダクトであるケーシング１を備え、該ケーシング１のガスタービン排ガスが導入される入口付近の内部に助燃バーナ２が配置され、その後流側に多数の伝熱管パネル３が配置されている。前記伝熱管パネル３は一般的には上流側から下流側に過熱器３ａ、蒸発器３ｂ及び節炭器３ｃが順に配置されているが、再熱器（図示せず）を配置する場合もある。
【０００５】
図５には従来の横型排熱回収ボイラの熱交換器の伝熱管パネル３の据付方法を示す。図５に示す横型排熱回収ボイラの伝熱管パネル３は、熱交換フィン巻チューブからなる伝熱管群と該伝熱管群の上部管寄せ４と下部管寄せ５を組み合わせた構成であるため、伝熱管パネル３の撓みによりフィン巻チューブが損傷しないように立て起こす必要がある。そのために伝熱管パネル３の立て起こし方法としては、図６に示すように立て起こし治具６に伝熱管パネル３の上部管寄せ４に設けられた仮設吊りラグ７を立て起こし治具６の固定ラグ８にボルト９で固定し、下部管寄せ５を立て起こし治具６の支持サポート１０に固定し、図５に示すように立て起こし治具６の上部吊りラグ１１及び下部吊りラグ１２をそれぞれのクレーンのワイヤ１３、１４で吊上げて立て起こし、立て起こし治具６を垂直にした状態で所定の作業床の位置に移動し、立て起こし治具６を地上に立て、クレーンで吊った状態で作業者は仮設足場１８で上部管寄せ４の仮設吊りラグ７と立て起こし治具６の固定ラグ８を連結していたボルト９を外して、立て起こし治具６の上部吊りラグ１１に係止させていた吊り込み用クレーンの吊り金具１５を取りはずし、伝熱管パネル３の固定ラグ１６（図６）に吊り込み用クレーンの吊り金具１５を取り付け、所定の吊りこみ位置に伝熱管パネル３を移動させていた。また、立て起こし治具６は再度２台のクレーンを使用し、元の地上へ吊り降ろして、次の伝熱管パネル３の立て起こしに備えていた。

【発明が解決しようとする課題】
上記従来技術は、図５に示す伝熱管パネル３の切り離し作業においては、高所に設置された仮設足場１８で、吊り込み用クレーンの吊り金具１５を立て起こし治具６の上部吊りラグ１１から伝熱管パネル３の固定ラグ１６に取り付け換える作業と、伝熱管パネル３の仮設吊りラグ７と立て起こし治具６の固定ラグ８を連結していたボルト９を取り外す作業などの危険な作業をすることになる。また、図６で示す本設の固定ラグ１６に吊り込み用クレーンの吊り金具１５を取付けた後、仮設吊りラグ７の前記クレーンの吊り金具１５を取り外す一連の作業が完了するまでクレーンが拘束され、作業能率が悪いという問題があった。
【０００９】
本発明の課題は、吊り込み用クレーンへの掛け替えのための吊り金具の掛け替え工程を不要として立て起こし作業時間を短縮し、また、危険な高所作業を排除した横型排熱回収ボイラの熱交換器の伝熱管パネルの据付方法と伝熱管パネルの立て起こし治具を提供することである。
【００１０】
【課題を解決するための手段】
上記本発明の課題は、伝熱管群と該伝熱管群の上下管寄せとからなる伝熱管パネルを横型排熱回収ボイラの設置部位に据付するために吊り上げクレーンで立て起こす伝熱管パネルの立て起こし方法において、立て起こし治具上に伝熱管パネルを載せ、伝熱管パネルの上部管寄せを立て起こし治具に固定しないで立て起こし治具と伝熱管パネルの上端部をそれぞれ吊り上げクレーンで立て起こす伝熱管パネルの立て起こし方法により解決される。
【００１１】
また、上記伝熱管パネルの立て起こし方法において、立て起こし治具上に伝熱管パネルを載せ、伝熱管パネルの下部管寄せを立て起こし治具に固定し、上部管寄せは立て起こし治具に固定しないで、立て起こし治具及び伝熱管パネルの上部管寄せをそれぞれ吊り上げクレーンで吊り上げながら立て起こすことができる。
【００１２】
さらに、立て起こし治具及び伝熱管パネルの上部管寄せをそれぞれ吊り上げクレーンで吊り上げながら立て起こす際には立て起こし治具の下部管寄せ固定部に設けたピンを中心に立て起こし治具を回転させることで、常に立て起こし治具のピンを中心に伝熱管パネルを立て起こすことができ、回動支点が常に同じ部位であるので伝熱管パネルの立て起こし作業が安定する。
【００１３】
また、本発明の上記課題は、上記伝熱管パネルの立て起こし作業を実施するための伝熱管群と該伝熱管群の上下管寄せとからなる伝熱管パネルを横型排熱回収ボイラの設置部位に据付するために、前記伝熱管パネルを保持して吊り上げクレーンで立て起こす伝熱管パネルの立て起こし治具であって、伝熱管パネル下部管寄せを固定するための固定部と、下端部に設けた下部サポートと該下部サポートの基部に該下部サポートのなす平面に対して直角方向に伸びるように設けたストッパーと前記下部サポートとストッパーとを回転自在の連結するピンとを備えた伝熱管パネルの立て起こし治具により解決される。
【００１４】
【発明の実施の形態】
図２は、本発明の実施の形態の立て起こし治具を使用した概略作業要領を示す図、図３は図２に示した立て起こし治具の平面図（図３（ａ））と側面図（図３（ｂ））、図４は伝熱管パネル３が図２に示した立て起こし治具を使用して立て起こされ、横型排熱回収ボイラに据え付けられる一連の作業の概略を示す図である。
【００１５】
図２と図３に示すように、伝熱管パネル３は立て起こし治具６上に載せられ、伝熱管パネル３の上部管寄せ４に取付けられた本設の吊上用ラグ１７にボルト９を取り付け、立て起こし治具６に設けられた荷重受け固定ラグ２０と接するように伝熱管パネル３を調整する。
【００１６】
伝熱管パネル３の上部管寄せ４に取付けられた吊上用ラグ１７に図２に示すように吊上げ用クレーンのワイヤ２２を取付け、立て起こし用のクレーンのワイヤ１３を立て起こし治具６の上部吊りラグ１１に取付ける。
【００１７】
立て起こし治具６の下端部には、その長手方向に伸びた下部サポート２７と該下部サポート２７の基部に設けられたピン２８と該ピン２８の取り付け部に下部サポート２７のなす平面に対して直角方向に伸びるストッパー２９が設けられており、立て起こし治具６はピン２８を支点として立て起こされ、立て起こし治具６の立て起こし操作により、ピン２８を中心に回転するストッパー２９が下部サポート２７に当接すると伝熱管パネル３が立て起こし治具６の下部サポート２７に対して角度８０度で止まる構造としている。
【００１８】
立て起こし治具６を吊上げると、立て起こし治具６の下端部には下部サポート２７とピン２８と該ピン２８の取り付け部に設けた下部サポート２７のなす平面に対し直角方向に伸びるストッパー２９がピン２８を支点として立て起こされる。前記立て起こし操作によりストッパー２９が下部サポート２７に当接すると伝熱管パネル３が立て起こし治具６の下部サポート２７に対して角度８０度で止まる構造になっているので、その時点で伝熱管パネル３の上部管寄せ４の吊上用ラグ１７にセットしておいた吊上げ用クレーンのワイヤ２２を巻上げ伝熱管パネル３を取り外し、伝熱管パネル３の所定の吊り込み作業を行う。伝熱管パネル３を取り外した後、立て起こし治具６は、立て起こし用クレーンのワイヤ２２を巻下げることにより元の定位置に戻る。
【００１９】
この方法では、図２に示すように伝熱管パネル３の自重を荷重受け固定ラグ２０に預けた状態で立て起こし、伝熱管パネル３を吊上げるため、伝熱管パネル３のフィン巻チューブに曲げ応力を掛けることなく吊上げ作業が可能となる。また、立て起こし治具６と伝熱管パネル３をボルト・番線等で固定していないので取り外しのための高所作業床・危険作業を排除することができる。
【００２０】
【発明の効果】
以上の説明のように、本発明によって高所での作業が排除されることにより、作業用床の設置が不要となり、伝熱管パネルの吊上げクレーンへの掛け替え作業が不要となることから、高所での危険な作業をなくし、かつ作業時間を短くすることができる。
【００２１】
また、伝熱管パネルの立て起こし操作がピン構造であるため、同一の繰り返し作業となり、吊上げの熟練工・監視員の少数化が図れる。
