Claims (9)
- 廃熱蒸気発生器において、縦型の強制流動蒸気発生器を起動するための方法であって、前記強制流動蒸気発生器に、作動流体として給水が供給され、前記強制流動蒸気発生器において、前記給水はまず、給水予熱器(1)を貫流した後に、蒸発器(2)を貫流し、その際に少なくとも部分的に蒸発し、部分的に蒸発した前記作動流体は、水分離システム(3)に供給され、前記水分離システム(3)内では、蒸発しなかった前記作動流体が、蒸発した前記作動流体から分離かつ回収される方法において、
前記水分離システム(3)内で回収された蒸発していない前記作動流体の少なくとも一部は、前記蒸発器(2)に測地学的に供給され、蒸発しなかった前記作動流体が蓄積し、特定の量を超えると、余剰の部分は自動的に、前記水分離システム(3)から排出されることを特徴とする方法。 - 前記水分離システム(3)が、分離器(4)及び瓶(5)を含んでおり、蒸発しなかった前記作動流体は、前記分離器(4)から再循環される、請求項1に記載の方法。
- 蒸発しなかった前記作動流体を、前記水分離システム(3)から前記蒸発器(2)に再循環させるために、遮断装置(6)が開かれ、再循環される前記作動流体の量が、ただ前記水分離システム(3)の形状によってのみ制御される、請求項1又は2に記載の方法。
- 廃熱蒸気発生器において、縦型の強制流動蒸気発生器を起動するための装置であって、
−給水ポンプ(7)を用いて給水供給管(8)を通じて作動流体として給水が供給され得る給水予熱器(1)と、
−前記作動流体の流れる方向において前記給水予熱器(1)の下流に接続され、前記作動流体によって貫流可能であり、前記作動流体を少なくとも部分的に蒸発させることが可能である蒸発器(2)と、
−前記蒸発器(2)の出口における、蒸発していない前記作動流体を蒸発した前記作動流体から分離することが可能である水分離システム(3)と、を有している装置において、
前記水分離システム(3)は、別個の容器として設計された分離器(4)及び瓶(5)を含んでおり、戻り配管(9)は、前記分離器(4)から、前記蒸発器(2)の接続点(10)に合流しており、前記分離器(4)内の前記戻り配管(9)のための作動流体出口(11)は、前記接続点(10)よりも上方に離れて位置しており、これによって、蒸発しなかった前記作動流体が前記戻り配管(9)を通って前記蒸発器(2)内に測地学的に戻ることが可能であり、さらに、流出導管(12)が、前記分離器(4)から分岐し、前記瓶(5)内に合流し、前記水分離システム(3)内に配置され、これによって、前記流出導管は、少なくとも一部が、前記戻り配管(9)の上方に配置されていることを特徴とする装置。 - 遮断装置(6)が、前記戻り配管(9)内に配置されている、請求項4に記載の装置。
- 逆止め弁(13)が、前記戻り配管(9)内に配置されている、請求項4又は5に記載の装置。
- 前記流出導管(12)が、前記分離器(4)の底面(14)を通って、前記分離器(4)内に突出している管(15)を含む、請求項4から6のいずれか一項に記載の装置。
- 第1の排出導管(16)が、前記分離器(4)の下端(17)に配置され、前記瓶(5)内に合流しており、これによって、前記分離器(4)を可能な限り完全に空にすることが可能である、請求項4から7のいずれか一項に記載の装置。
- 前記流出導管(12)の部分が、前記分離器(4)と前記瓶(5)との間でサイフォン様に設計されており、前記部分の最も深い位置(18)において、前記瓶(5)に合流する第2の排出導管(19)が設けられている、請求項4から6のいずれか一項に記載の装置。
