Description
図1のORC30は、図2のORC92と同様に機能する。具体的には、硫黄回収ユニット28の最後の熱交換器228からの加熱されたボイラ給水236は、図2のORC92に流入する加熱された流体94と同等である。硫黄回収ユニット28の最後の熱交換器228に流入する冷却されたボイラ給水234は、図2のORC92からの冷却された流体96と同等である。明らかなように、一部の実施形態では、冷却されたボイラ給水234は、熱交換器192、212、228のいずれかを通って、加熱されたボイラ給水236を生成する。
明らかなように、ガス化システムの一部の実施形態は、1つ、2つ、3つ、又は複数の有機ランキンサイクルシステム(22、30、64)を含む。言い換えると、ガス化システムを使用して加熱された流体を生成し、これを1つ又は複数の有機ランキンサイクルシステム(22、30、64)で使用できる。例えば、一部の実施形態では、高温の生のシンガスからの熱を利用して、ガス冷却システム(例えば、低温ガス冷却システム)、硫黄回収ユニット、抽気冷却システム、又はそれらの任意の組合せで、加熱された流体を生成できる。こうした実施形態では、ガス化システムの1つ、2つ、3つ以上の部分からの加熱された流体を合流させて、一つの有機ランキンサイクルシステム(22、30、64)に流したり、この加熱された流体を複数の有機ランキンサイクルシステム(22、30、64)に流したりできる。同様に、1つ又は複数の有機ランキンサイクルシステム(22、30、64)からガス化システム、ガス冷却システム、硫黄回収ユニット、抽気冷却システム、又はそれらの任意の組合せに、冷却された流体を流すこともできる。
