Description
また、本発明は、2010年2月19日に日本国に出願された特願2010−034776号に基づき優先権を主張し、その内容をここに援用する。
また、水(第1の作動流体)と当該水よりも沸点が低い第2の作動流体とを用いる従来の排熱回収方法は、200℃程度の比較的低温の熱源からの熱回収を念頭に置いたものであり、第2の作動流体を気化させて得られる蒸気の温度は、第1の作動流体を気化させて得られる蒸気の温度よりさらに低いため、比較的高温の排熱からの有効エネルギの回収は殆ど不可能である。
また、本発明は、効率、また省エネ率やCO2削減率が従来よりも高いエネルギ供給システムを提供することを目的とする。
〔第1実施形態〕
最初に、本発明の第1実施形態について図1及び図2を参照して説明する。
本第1実施形態に係るエネルギ供給システムP1は、図1に示すように、排ガス管1、高沸点熱媒蒸気発生器2、水蒸気発生器3、高沸点熱媒予熱器4、水予熱器5、高沸点熱媒蒸気過熱器6、水蒸気過熱器7、高沸点熱媒供給ポンプ8、給水ポンプ9、高沸点熱媒蒸気タービン発電機10、高沸点熱媒蒸気凝縮器11、復液タンク12、水蒸気タービン発電機13、水蒸気凝縮器14、復水タンク15及び冷却水供給装置16によって構成されている。なお、この図1において、符合Gは高温排ガス、R1は高沸点熱媒、R2は高沸点熱媒蒸気、R3は水、またR4は水蒸気を示している。
次に、本発明の第2実施形態について図3及び図4を参照して説明する。
なお、図3では、図1に示した第1実施形態に係るエネルギ供給システムP1の構成要素と同一の構成要素には同一符合を付している。
次に、本発明の第3実施形態について図7及び図8を参照して説明する。なお、図7では、図3に示した第2実施形態に係るエネルギ供給システムP2の構成要素と同一の構成要素には同一符合を付している。
(1)上記各実施形態では、蒸気圧が異なる2種類の液体、つまり水R3に加え、当該水R3よりも蒸気圧が低い高沸点熱媒R1を用いて高温排ガスGの排熱を熱回収するが、これに代えて、高沸点熱媒R1のみを用いて、あるいは蒸気圧が異なる3種類以上の液体を用いて高温排ガスGの排熱を熱回収するようにしても良い。
また、本発明によれば、上述したように排熱回収における有効エネルギの回収効率が高いので、従来よりもエネルギ効率が高いエネルギ供給システムを提供することができる。
