Abstract

(57)【要約】 【目的】二酸化炭素を用いて発電する場合ターピンより
の排気圧力を液化に適合した圧力として発電効率を高め
る。 【構成】二酸化炭素の液化時の圧力と冷却水の温度とか
ら最も効率のよい構成とする。

Description

【発明の詳細な説明】 水を用いる発電方式とは異り二酸化炭素を用いる場合に
はターピンよりの排気圧力を低くすると出力は得られる
けれども液化に伴う加圧エネルギーが大きくなりその分
出力を消費する。二酸化炭素の液化は５６．５気圧の時
に２０℃に冷却すればよいので冷却水は一般に２０℃前
後であるから排気圧を６０気圧前後に設定すればこれに
若干の圧力を加えて液化出来、その必要エネルギーも小
さくてすむ。一般に加圧機の効率は低いので圧力差の大
きい所で使用するのは得策でない。このような考え方の
もとで加圧機の効率、冷却水の温度等を基礎として排気
圧力を調節して高い効率の発電をする方式である。
【図面の簡単な説明】
１は二酸化炭素の加熱器で地熱火力等を用いる。２はタ
ーピンで３は発電機、４は冷却機で５は二酸化炭素液の
タンクである。６は二酸化炭素液を加熱機に送るポンプ
である。
