Abstract

PROBLEM TO BE SOLVED: To increase power generating efficiency by causing a pressure exhausted from a turbine to be a prescribed atmospheric pressure and cooling and liquefying the same when thermal or geothermal power generation is performed by using carbon dioxide.
SOLUTION: When thermal or geothermal power generation is performed by using carbon dioxide, although an output is obtained by reducing a exhaust pressure from a turbine 2, a pressure energy is increased following liquefaction and output consumption is increased by an amount equivalent to this. Since for liquefaction of carbon dioxide, the dioxide is cooled clown to 20°C at the time of 56.5 atm, cooling water is generally around 20°C and thus by setting an exhaust pressure to around 60 atm, liquefaction is performed only by adding a small pressure and energy needed for this is small. It is not advisable to use a pressure machine in a place having a large pressure difference because the efficiency of the pressure machine is small. Thus, highly efficient power generation is performed.

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。 Used DETAILED DESCRIPTION OF THE INVENTION water power generation method and increases the pressure energy due to liquefaction but output is obtained with lower exhaust pressure from Turpin in the case of using the roasted carbon dioxide consumes correspondingly output to. 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。 Liquefaction of carbon dioxide can be liquefied by adding a little pressure exhaust pressure to be set at around 60 atmospheres since it is sufficient to cool to 20 ° C. cooling water is around generally 20 ° C. at 56.5 atm, the necessary energy is also small. 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。 Efficiency generally the intensifier is not advisable to use a large at the pressure differential is lower. 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。 Such original by pressing machine efficiency concept is a method of power generation of the adjustment to a high efficiency exhaust pressure on the basis of the temperature of the cooling water.
