Abstract
Description
その一方、タービンの運転中のロータの温度分布は、ロータ回転軸に対して対称である。このため、ロータは、熱伸びしてもロータ回転軸の高さは大きく変位しない。
その結果、タービンの運転中、車室がロータに対して相対的に上方に動き、車室とロータとの間の隙間は、上部で広がり下部で狭まることとなる。
車室の熱変形が大きい場合には、車室とロータとが下部で接触して振動が発生する。熱変形が極端に大きな場合には、車室とロータとが強く接触してこれらの車室とロータとが損傷して、タービンの運転に支障をきたすこともある。
特許文献1(段落[0044]~[0045]及び図4など参照)に開示された技術では、前記支持台に相当する支柱(6)の内部に通路(13)を形成し、この通路(13)内に、空気や水等の冷却流体を流通させて支柱(6)を冷却している。これにより、支柱(6)の熱膨張(熱伸び)を抑え、タービン車室(1)の鉛直上方への変位を抑えている。
したがって、ランニングコストや設備費の増大を抑えつつ、支持部の熱伸び・熱変形を抑制することができる。
以下に示す各実施形態はあくまでも例示に過ぎず、以下の各実施形態で明示しない種々の変形や技術の適用を排除する意図はない。以下の各実施形態の各構成は、それらの趣旨を逸脱しない範囲で種々変形して実施することができると共に、必要に応じて取捨選択することができ、あるいは適宜組み合わせることが可能である。
以下の各実施形態では、本発明をタービンに適用した例を説明する。
[1-1.タービンの全体構成]
以下、図1を参照して本実施形態としてのタービンの全体構成について説明する。
図1は、タービンの全体構成を示す模式的な側面図である。
タービン(回転機械)1は、ロータ(回転体)2と、ロータ2を収容する車室(ケーシング)3と、ロータ2を回転可能に支持する軸受箱(軸受部)4と、地盤200上で車室3を支持する車室支持部(以下「支持部」とも表記する)5と備えている。
ロータ2は、その回転中心線(以下「ロータ回転中心線」とも表記する)CLを水平にした姿勢で車室3内に収容されている。ロータ2は、ロータ本体(回転体本体)20と、ロータ本体20の軸方向両外側に設けられた一対のロータ軸端(回転軸端)21とを、ロータ回転中心線CL上に並べて一体形成されている。
ロータ本体20は車室3の内部に収容されている。各ロータ軸端21は車室3を貫通しており、各ロータ軸端21の先端側は車室3の外部に露出して軸受箱4により支持されている。
ロータ本体20は車室3の内部を流れる作動流体(例えば過熱蒸気や燃焼ガス)によって駆動されて回転力を付与され、この回転力によってロータ軸端21を介して連結された発電機や圧縮機(いずれも図示略)を駆動する。
支持部5は、上車室30の本体又は下車室31の本体、本実施形態では上車室30の本体(以下「上車室本体」とも表記する)30aの四隅近傍からロータ軸端21の軸方向に突出した突出部50と、地盤200上に立設された箱型形状の支持台51とを備えており、支持台51の上面(天井壁外面)51a1に突出部50を載置することで車室3が、支持部5を介して地盤200上に支持される。突出部50はその形状から猫足と呼ばれており、以下、突出部50を猫足50とも表記する。
図2を参照して、軸受箱4及び支持台51についてさらに説明しつつ、本発明の第1実施形態としての車室支持部の冷却装置100を説明する。
図2は、本発明の第1実施形態としての車室支持部の冷却装置100の構成を示す模式的な斜視図を要部拡大図と共に示す図である。
軸受箱4のロータ軸端21を支持する軸受面(ロータ軸端21が摺接する摺接面)41には、潤滑ライン6(図1では省略)により、低温(例えば外気温度程度)の潤滑油(潤滑流体)が順次供給される。支持台51は中空部51Aを有した中空箱型形状をしており、潤滑ライン6はこの中空部51Aを経由して軸受面41に供給される。
潤滑ライン6は、支持台51に内蔵された熱交換部60と、給油管61と、軸受箱4に穿設された給油孔62と、ロータ軸端21と軸受面41との間の微小なクリアランス63と、軸受箱4に穿設された排油孔64と、排油管65とが、上流側からこの順に並べられると共に接続されて形成される。熱交換部60には、タンクやポンプや配管等からなる潤滑油供給装置(図示省略)から潤滑油が供給される。
なお、図2では、便宜的に、クリアランス63を大きく示し、図中左側の支持台5についての潤滑ライン6,冷却装置100を省略している。
複数の枝管60aは水平方向に並べられて設けられている。各枝管60aは、支持台51の正面51bにおいて一端(図2中右端)を、前記潤滑油供給装置に接続された水平管60a1と、水平管60a1の他端(図2中左端)に上端を接続された垂直管60a2と、垂直管60a2の下端に一端(図2中左端)を接続された水平管60a3とを備える。
つまり、各枝管60aは、支持台51の中空部51A内を折り返すUターン形状をしている。
また、各枝管60aを支持台51の中空部51A内で折り返すUターン形状とすることで、各枝管60aの管長(流路長)を長くして熱交換面積を広くとることができる。これにより、支持台51が効果的に冷却されて熱伸びが抑制され、且つ、支持台51を広い範囲で冷却して均等な温度分布とすることにより熱変形が抑制される。
本発明の第1実施形態によれば、軸受面41に潤滑油を供排する潤滑ライン6の一部を、支持台51に熱交換部60として内蔵することで、この熱交換部60を流通する潤滑油により、支持部5(猫足50及び支持台51)を冷却することができる。
したがって、支持部5の熱伸びを抑制することができ、特にその厚み方向への熱伸びを抑制することで、車室3の鉛直上向きの変位を抑制できる。
さらに、潤滑油を冷却媒体として兼用するので、支持台51及び猫足50を冷却するための冷却媒体を別途用意する必要がなく、支持部5を冷却するための専用の設備が殆ど不要となる。
したがって、ランニングコストや設備費の増大を抑えつつ、支持台51及び猫足50を冷却して支持台51及び猫足50の熱伸び・熱変形を抑制することができる。
また、支持台51よりも高温となる猫足50に近い上部から、熱交換器60に潤滑油が供給されるので、最も低温の状態の潤滑油により高温となる猫足50を効率的に冷却することができる。
(1)第1変形例
背景技術の説明の中で上述したように猫足50には先細りとなる熱変形(以下「先細り熱変形」とも表記する)が生じる。この先細り熱変形は、猫足50の根本に近づくほど、つまり図2中右上に位置して上車室本体30aに近くなるほど高温となる(逆の言い方をすれば先端になるほど低温となる)温度勾配が生じることに起因する。
そこで、猫足50の根元に近い枝管60aほど潤滑油が多く流れるようにしてもよい。つまり、枝管60a(1)の潤滑油の流量F(1)、枝管60a(2)の潤滑油の流量F(2)、枝管60a(3)の潤滑油の流量F(3)を、この順に大きくなるように設定してもよい(流量F(1)<流量F(2)<流量F(3))。
この流量設定の具体的な手法は何ら限定されないが、例えば、枝管60a(1),60a(2),60a(3)の順に内径が大きくなるように管サイズを設定してもよい〔枝管60a(1)の内径<枝管60a(2)の内径<枝管60a(3)の内径〕。或いは、枝管60a(1),60a(2),60a(3)内にオリフィスを設置して流量を調整するようにしてもよいし、枝管60a(1),60a(2),60a(3)への各流量を調整する調整弁を設けて流量を調整するようにしてもよい。
本変形例について、図3を参照して説明する。
図3は、本変形例の構成を示す模式的な側面図である(軸受箱4及びロータ軸端21は省略)。
図3に示すように、耐熱性に優れた保温層7を、上車室本体30a及び猫足50において外部に表出する外周面、つまり図3において網点を付した箇所に設けてもよい。
上述したように、猫足50には、先端側ほど低温となる温度勾配があることがわかっており、保温層7を設けることで、この温度勾配を緩和することができる。つまり、猫足50の根元から先端にかけての温度分布を平坦化できる。これは、高温の上車室本体30aから離れているために放熱し易い猫足50の先端側が、保温層7を設けることで当該放熱が抑制されて低温化が抑制されるので、前記温度勾配が緩和されるためである。これにより、前記温度勾配に伴う猫足50の先細り熱変形を抑制することができる。
このように、支持台51に熱交換部60を内蔵すると共に保温層7を上車室本体30aと猫足50との外周面に設けることで、相乗的に猫足50及び支持台51の熱伸び・熱変形を抑制できる。
[2-1.構成]
図4を参照して、本実施形態の車室支持部の冷却装置100Aを説明する。なお、上記第1実施形態と同様の構成要素については同一の符号を付してその説明を省略する。
図4は、本発明の第2実施形態としての車室支持部の冷却装置100Aの構成を示す模式的な斜視図を、要部拡大図及び制御ブロック図と共に示す図である。なお、図4では、便宜的に、クリアランス63を大きく示し、図中左側の支持台5についての潤滑ライン6,冷却装置100Aを省略している。
具体的には、前記潤滑油供給装置(図示省略)が給油管61′に接続されて、前記潤滑油供給装置から潤滑油が先ず給油管61′に供給される。そして、給油管61′から分岐した分岐管66が分配ヘッダ67の延在方向中央に接続される。
分配ヘッダ67は、枝管60a(1),60a(2),60a(3)の並び方向(ここでは水平方向)に延在し、分配ヘッダ67の周面にはこれらの枝管60a(1),60a(2),60a(3)の入口が並列的に接続される。枝管60a(1),60a(2),60a(3)の出口は集合ヘッダ60bの周面に接続され、集合ヘッダ60bの出口は、合流管68の入口に接続され、合流管68の出口は、分岐管66と給油管61′との接続部よりも下流側(軸受面41側)で給油管61′に接続されている。
また、支持台51の温度(以下「支持台温度」と表記する)T1を検出する温度センサ(温度検出手段)12が備えられると共に、この温度センサ12により検出された支持台温度T1の温度が高くなるほど、流量調整弁11の作動を制御して流量調整弁11の開度を大きくする制御装置10が備えられている。
或いは、支持台温度T1から基準温度THを減じた温度差(=T1-TH)が大きいほど、流量調整弁11の一回当たりの開度変更量を大きく設定してもよい。
なお、基準温度TLは、基準温度THよりもΔT〔>0(零)〕だけ低い温度に設定されており、これにより制御のハンチングを防止している。
この他の構成は第1実施形態と同様であるので説明を省略する。
本実施形態では、図5に示すフローチャートに示すように制御が行われる。
先ず、ステップS10において、温度センサ12により支持台温度T1が検出される。
次いで、ステップS20において、この支持台温度T1と基準温度THとの比較が行われ、支持台温度T1が基準温度THよりも高い場合(T1>TH)には、ステップS30に進んで流量調整弁11の開度を所定開度だけ増加する一方、支持台温度T1が基準温度TH以下(T1≦TH)の場合にはステップS40に進む。
ステップS40では、支持台温度T1と基準温度TLとの比較が行われ、支持台温度T1が基準温度TLよりも低い場合(T1<TL)には、ステップS50に進んで流量調整弁11の開度を所定開度だけ減少してリターンする一方、支持台温度T1が基準温度TL以上(T1≧TL)の場合には、流量調整弁11の開度を変更せずにリターンする。
(1)支持台温度T1に替えて、猫足50の温度(以下「猫足温度」と表記する)T2を検出し、猫足温度T2が基準温度THよりも高い場合には、流量調整弁11の開度を大きくし、猫足温度T2が基準温度TLよりも低い場合には、流量調整弁11の開度を小さくするようにしてもよい。
或いは、熱交換部60の入口又は出口における潤滑油の温度TFを計測し、支持台温度T1(又は猫足温度T2)と潤滑油温度TFとの差ΔT(=T1-TF又はT2-TF)が大きいほど流量調整弁11の開度を開くようにしてもよい。
(1)上記各実施形態では、潤滑油が流通する熱交換部60を支持台51に内蔵して支持台51を冷却するようにしたが、この態様に限定されない。例えば、熱交換部を、潤滑ラインを構成する管の一部を猫足50の所定箇所(例えば根元)に接触させることで構成してもよい。或いは、熱交換部を、潤滑ラインを構成する管の一部を、支持台51の外側に巻き付けるなどして支持台51の外面と接触させることで構成してもよい。
