Abstract
Description
(1)高温放熱物体を一時集積して貯蔵する高温放熱物体貯蔵ヤードの建屋の天井部に、頂部が上方へ延びる筒状部となっているチムニーを設け、この筒状部の所要個所に、上昇気流で発電する発電タービンを設置してある。これにより、熱の投入を伴って製造された高温放熱物体の保有する熱で、主として対流伝熱によって高温放熱物体貯蔵ヤードの空気を昇温させ、この昇温した空気が密度低下して浮力が生じることで発生する上昇気流を、上記チムニーの筒状部へ集めて流通させることができる。そして、このチムニーの筒状部を流通する上昇気流により上記発電タービンを回して発電を行わせることができるため、上記高温放熱物体の保有する熱を有効利用することができる。
(2)高温放熱物体貯蔵ヤードの建屋の側壁の下部に吸気口を設けることで、吸気口より建屋内の下部へ温度の低い外気を取り込むことができ、この建屋の下部に取り込んだ空気を、建屋内にて高温放熱物体の保有する熱により昇温させて上昇気流を生じさせることができる。このため、建屋内にチムニーに向かう上昇気流を効率よく発生させることができ、発電タービンにて効率よく発電を行わせることができる。

(6)(1)の構成において、高温放熱物体を、製鉄所の熱間圧延設備にて製造される熱延コイルとし、該熱延コイルを一時集積して貯蔵するようにしてある高温放熱物体貯蔵ヤードの建屋の一側部に、熱間圧延設備の建屋の熱延コイル搬出側端部を連通接続して吸気できるようにすることにより、製鉄所の熱間圧延設備にて高温状態で製造される熱延コイルが保有する熱を、発電に有効利用することができる。更に、熱間圧延設備の建屋内にて熱間圧延処理工程で放出される熱により外気温に比して暖められている空気を、上記熱延コイルを貯蔵する高温放熱物体貯蔵ヤードの建屋内へ吸気できる。このため、建屋内にて熱延コイルの保有する熱を受けて昇温する空気の温度をより高めることができ、チムニーの筒状部の上端出口での空気の最終温度を高めることができるようになるため、チムニーの筒状部を流通する空気のドラフトの強さを増強でき、発電タービンによる発電量を増大させることが可能になる。
(7)(6)の構成において、熱延コイルを一時集積して貯蔵する高温放熱物体貯蔵ヤードの建屋における熱間圧延設備の建屋との接続側となる一側部を除く側壁の内側に、輻射受熱パネルを設けることにより、建屋内における空気の昇温効率をより高めることができる。そのため、上記建屋内で発生させる上昇気流をより増強させることができ、発電量の更なる増大化を図ることが可能になる。
(8)高温放熱物体貯蔵ヤードの建屋の床部に、すのこ状部材を設けて、高温放熱物体を載せるようにすることで、上記高温放熱物体貯蔵ヤードの建屋内にて、上記すのこ状部材の下側を通して高温放熱物体、又は、高温放熱物体としての鉄鋼中間製品、又は、鉄鋼中間製品としての熱延コイルの下側へ空気を通気させることができる。これにより、上記高温放熱物体、又は、高温放熱物体としての鉄鋼中間製品、又は、鉄鋼中間製品としての熱延コイルが保有する熱の建屋内の空気への対流熱伝達を促進することができ、上記建屋内部の空気をより効率よく昇温させ、建屋内で発生させる上昇気流を更に増強させることで、発電量の更なる増大化を図ることが可能になる。
(9)高温放熱物体貯蔵ヤードの建屋の内底部に、高温耐性のある断熱材を敷き詰めるようにすることで、建屋の底部から地盤への熱の散逸を抑えることができる。これにより、上記建屋の内部で空気の昇温に充てる熱量を増加させることができ、建屋内の空気の昇温効率を高めることができるため、建屋内で発生させる上昇気流の増強化による発電量の更なる増大化を図ることが可能になる。
(10)高温放熱物体を一時集積して貯蔵する高温放熱物体貯蔵ヤードの建屋の所要個所を、建屋と別体に外部に設けた上下方向に延びる排気タワーの下端部に、連結ダクトを介して連通接続し、排気タワー又は連結ダクトの所要個所に発電タービンを設け、建屋内で昇温されて浮力を生じる空気が連結ダクトを経て排気タワーへ導かれ、排気タワー内を流通するときの気流で発電させる。これにより、熱の投入を伴って製造された高温放熱物体の保有する熱により、主として対流伝熱によって高温放熱物体貯蔵ヤードの建屋内の空気を昇温させ、この昇温して浮力が生じた空気を、連結ダクトを介して排気タワーの下端部に導くことで、排気タワー内に上昇気流を発生させ、この上昇気流により発電タービンを回して発電できる。
(11)更に、排気タワーは、高温放熱物体貯蔵ヤードの建屋とは別体なので、本発明の高温放熱物体貯蔵ヤード発電装置を実現する上で日数を必要とする排気タワーの建造工事を、高温放熱物体貯蔵ヤードに何ら影響を及ぼすことなく実施できる。これにより、本発明の高温放熱物体貯蔵ヤード発電装置を、既設の高温放熱物体貯蔵ヤードに導入する場合でも、既設の高温放熱物体貯蔵ヤードの操業に支障をきたす虞を回避でき、その操業を継続できる。
(12)高温放熱物体を一時集積して貯蔵する高温放熱物体貯蔵ヤードの建屋の所要個所を、建屋と別体に外部に設けた上下方向に延びる排気タワーの下端部に、連結ダクトを介して連通接続し、建屋内の天井部の所要個所に、建屋内に貯蔵される高温放熱物体へ水を噴霧するための水噴霧ノズルを設けている。更に、排気タワー又はダクトの所要個所に発電タービンを設けて、建屋内で昇温されて浮力を生じる空気と共に、水噴霧ノズルより噴霧する水が高温放熱物体の保有する熱で蒸発して生じる水蒸気を上記連結ダクトを経て排気タワーへ導いて、空気と水蒸気が排気タワー内を流通するときの気流で発電させる。これにより、上記(11)(12)と同様の効果に加えて、水噴霧ノズルより噴霧する水を高温放熱物体の保有する熱で蒸発させることで、大量の昇温した水蒸気が発生し、この発生した水蒸気を、建屋より連結ダクトを経て排気タワーへ導かれる空気流れに合流させることで、排気タワー内を上昇する昇温した気体の量を増大させることができる。これにより、排気タワー内を上昇する気流の風速を飛躍的に増大させ、発電タービンにより回収可能なエネルギーをより増大させ、発電タービンの出力を格段に増加させることができる。
(13)建屋と別体の排気タワーとして、既設の排気設備の煙突を用いることにより、排気タワーの建造工事を省略できるため、本発明の高温放熱物体貯蔵ヤード発電装置を、より容易に実現できる。
(14)高温放熱物体を、製鉄所における鉄鋼中間製品とし、排気タワーの下端部に連結ダクトを介して連通接続する高温放熱物体貯蔵ヤードの建屋を、鉄鋼中間製品を一時集積して貯蔵する貯蔵ヤードの建屋とすることにより、製鉄所にて高温状態で製造される鉄鋼中間製品が保有する熱を、発電に有効利用してエネルギーとして回収できる。
(15)高温放熱物体としての鉄鋼中間製品を、製鉄所の熱間圧延設備にて製造される熱延コイルとし、排気タワーの下端部に連結ダクトを介し連通接続する鉄鋼中間製品を一時集積して貯蔵するための高温放熱物体貯蔵ヤードの建屋としての貯蔵ヤードの建屋を、コイルヤードの建屋とする。これにより、高温状態で製造される熱延コイルが保有する熱を、発電に有効利用してエネルギーとして回収できる。
(16)排気タワーの下端部に連結ダクトを介し連通接続する鉄鋼中間製品を一時集積して貯蔵するコイルヤードの建屋の一側部に、熱間圧延設備の建屋の熱延コイル搬出側端部を連通接続して吸気できるようにする。これにより、熱間圧延設備の建屋内にて熱間圧延処理工程で放出される熱により外気温に比して暖められている空気を、熱延コイルを貯蔵するコイルヤードの建屋内へ吸気できるため、建屋内にて熱延コイルの保有する熱を受けて昇温する空気の温度をより高めることができる。そして、コイルヤードの建屋より連結ダクトを経て排気タワーへ導かれる空気の温度もより高めることができるため、排気タワー内の上昇気流の流速を増強でき、発電タービンによる発電量を増大させることができる。
(17)高温放熱物体を一時集積して貯蔵する高温放熱物体貯蔵ヤードの建屋の天井の中央部に、建屋の上側に設けた上下方向に延びる排気タワーの下端部を連通接続する。更に、建屋の周壁の所要の複数個所に、建屋周壁の内面に沿わせて水平方向に空気を流入できる空気ダクトを、各空気ダクトを通して建屋内へ水平方向に流入する空気の流入方向が平面視で時計回り方向又は反時計空気回り方向のいずれか一方に揃うようにして設け、排気タワーの所要個所に、発電タービンを設置して上昇気流で発電させる。これにより、熱の投入を伴って製造された高温放熱物体の保有する熱により、主として対流伝熱によって高温放熱物体貯蔵ヤードの建屋内の空気を昇温させ、この昇温した空気に浮力が発生することで生じる上昇気流を、建屋の天井の中央部に接続してある排気タワーに集めて流通させることで発電タービンを回して発電できる。更に、建屋内の昇温した空気が排気タワーに向かうことに伴って建屋の周壁に設けた各空気ダクトを通して建屋外部の空気が建屋内へ導かれるときには、各空気ダクトより流入する空気流れの方向が、建屋の周壁の内面に沿う水平方向で且つ平面視で時計回り方向又は反時計空気回り方向のいずれか一方に揃えられているため、建屋内に、鉛直成分の少ない旋回流となる空気流れを発生させることができる。これにより、建屋内の空気の高温放熱物体との熱交換時間を増大させることができ、建屋内の空気を効率よく昇温でき、より大きな浮力を生じた昇温された空気を排気タワーへ導くことができる。これにより、排気タワーの内部を上昇する空気量を増大させることができ、発電タービンにより回収可能なエネルギーを増大させることができるため、発電タービンの出力を増加させることができる。
(18)よって、高温放熱物体貯蔵ヤードの建屋に本発明の高温放熱物体貯蔵ヤード発電装置を装備するために要する初期コストの回収期間を短縮できる。
(19)高温放熱物体を一時集積して貯蔵する高温放熱物体貯蔵ヤードの建屋の天井の中央部に、建屋の上側に設けた上下方向に延びる排気タワーの下端部を連通接続し、建屋内の天井部の所要個所に、建屋内に貯蔵される高温放熱物体へ水を噴霧するための水噴霧ノズルを設ける。更に、建屋の周壁の所要の複数個所に、建屋周壁の内面に沿わせて水平方向に空気を流入させる空気ダクトを、各空気ダクトを通して建屋内へ水平方向に流入する空気の流入方向が、平面視で時計回り方向又は反時計空気回り方向のいずれか一方に揃うようにして設ける。更に、排気タワーの所要個所に、発電タービンを設置して、空気ダクトより建屋内に流入することにより建屋内で旋回流となる空気と共に、水噴霧ノズルより噴霧する水が高温放熱物体の保有する熱で蒸発して生じる水蒸気を上記排気タワーへ導いて、空気と水蒸気が排気タワー内を上昇する上昇気流で発電タービンを駆動して発電させる。これにより、上記(17)(18)と同様の効果に加えて、水噴霧ノズルより噴霧する水を高温放熱物体の保有する熱で蒸発させることで、大量の昇温した水蒸気が発生し、この発生した水蒸気を、建屋内にて旋回流となる空気流れに合流させることで、建屋内より排気タワーへ向かう昇温した気体の量を増大させることができる。よって、排気タワーの内部を上昇する気流の風速を飛躍的に増大させることができ、発電タービンにより回収可能なエネルギーをより増大させて、発電タービンの出力を格段に増加させることができる。
(20)高温放熱物体を、製鉄所における鉄鋼中間製品とし、周壁の所要の複数個所に空気ダクトを設けた高温放熱物体貯蔵ヤードの建屋を、鉄鋼中間製品を一時貯蔵するための貯蔵ヤードの建屋とすることにより、製鉄所にて高温状態で製造される鉄鋼中間製品が保有する熱を、発電に有効利用してエネルギーとして回収できる。
(21)高温放熱物体としての鉄鋼中間製品を、製鉄所の熱間圧延設備にて製造される熱延コイルとし、周壁の所要の複数個所に空気ダクトを設けた鉄鋼中間製品を一時貯蔵する高温放熱物体貯蔵ヤードの建屋としての貯蔵ヤードの建屋を、コイルヤードの建屋とした構成とすることにより、高温状態で製造される熱延コイルが保有する熱を、発電に有効利用してエネルギーとして回収できる。
(22)高温放熱物体を一時集積して貯蔵する高温放熱物体貯蔵ヤードの建屋の天井の所要個所に、建屋の上側に設けた上下方向に延びる排気タワーの下端部を連通接続し、建屋内部の天井部の所要個所に、水噴霧ノズルを設けて、送水ポンプに水供給ラインを介して接続する。更に、排気タワーの所要個所に、発電タービンを設置して上昇気流で発電させるので、熱の投入を伴って製造された高温放熱物体の保有する熱により、主として対流伝熱によって高温放熱物体貯蔵ヤードの空気を昇温させると共に、高温放熱物体の保有する熱により水噴霧ノズルより噴霧する水を蒸発させて大量の昇温した水蒸気を発生させることができる。そして、昇温した空気と水蒸気に浮力が生じることで発生する上昇気流を、排気タワーへ集めて流通させて発電タービンを回して発電させることができる。このため、対流伝熱のみによって高温放熱物体貯蔵ヤードの空気を昇温させる場合に比して、排気タワーを上昇する気流の風速を飛躍的に増大させることができ、発電タービンにより回収可能なエネルギーを増大させることができるため、発電タービンの出力を格段に増加させることができる。
(23)よって、高温放熱物体貯蔵ヤードの建屋に本発明の高温放熱物体貯蔵ヤード発電装置を装備するために要する初期コストの回収期間を短縮させることができる。
(24)高温放熱物体を一時集積して貯蔵する高温放熱物体貯蔵ヤードの建屋の天井の所要個所に、建屋の上側に設けた上下方向に延びる排気タワーの下端部を連通接続し、建屋内部の天井部の所要個所に、水噴霧ノズルを設けて、水噴霧ノズルの設置高さ位置よりも高所位置に設けた雨水タンクに水供給ラインを介して接続する。更に、排気タワーの所要個所に、発電タービンを設置して上昇気流で発電させることによって、上記(22)(23)と同様の効果を得ることができる。更に、雨水タンク内の雨水を、落下エネルギーにより建屋の天井部に設けた各水噴霧ノズルへ噴霧用の水として供給できるため、各噴霧ノズルへの送水に要する送水エネルギーを低減でき、高温放熱物体貯蔵ヤードに貯蔵する高温放熱物体の保有する熱をエネルギーとして回収するために消費されるエネルギーを削減できる。
(25)建屋内部の天井部の所要個所に多数の水噴霧ノズルを設け、各水噴霧ノズルに個別に対応する水供給バルブを備えることで、高温放熱物体貯蔵ヤード内にて、比較的高温の高温放熱物体群に選択的に水噴霧ノズルより水を噴霧することができる。これにより、噴霧する水を効率よく蒸発させて水蒸気を発生させることができると共に、蒸発せずに高温放熱物体貯蔵ヤード内に水が溜まる虞を未然に防止できる。
(26)高温放熱物体を、製鉄所における鉄鋼中間製品とし、天井部の所要個所に水噴霧ノズルを設けた高温放熱物体貯蔵ヤードの建屋を、鉄鋼中間製品を一時貯蔵するための貯蔵ヤードの建屋とすることにより、製鉄所にて高温状態で製造される鉄鋼中間製品が保有する熱を、発電に有効利用してエネルギーとして回収できる。
(27)高温放熱物体としての鉄鋼中間製品を、製鉄所の熱間圧延設備にて製造される熱延コイルとし、天井部の所要個所に水噴霧ノズルを設けた鉄鋼中間製品を一時貯蔵する高温放熱物体貯蔵ヤードの建屋としての貯蔵ヤードの建屋を、コイルヤードの建屋とすることにより、高温状態で製造される熱延コイルが保有する熱を、発電に有効利用してエネルギーとして回収できる。

また、コイルヤード201は、通常、新たに製造された保有熱の大きな熱延コイル202が順次搬入されると、コイルヤード201に既に貯蔵されている熱延コイル202のうち、最も先に搬入されたもの、すなわち、最も長く熱を放散して温度が低くなった熱延コイル202が図示しない搬出口を通して順次搬出される。よって、コイルヤード201の建屋203に、保有熱が大きくて比較的高温の熱延コイル202が新たに搬入された場合は、各水噴霧ノズル209ごとに装備してある水供給バルブ213のうち、新たに搬入された熱延コイル202の上方に位置する水噴霧ノズル209に対応する水供給バルブ213を開操作して、建屋203に新たに搬入された保有熱の大きな熱延コイル202へ水の噴霧を開始すればよい。
