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 deg.C at the time of 56.5 atm, cooling water is generally around 20 deg.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.

To do. The liquefaction of carbon dioxide can be cooled to 20 ° C. at 56.5 atm, so the cooling water is generally around 20 ° C., so if the exhaust pressure is set to around 60 atm, it can be liquefied by applying a slight pressure to it. It requires less energy. Since the efficiency of the pressurizer is generally low, it is not advisable to use it in a place where the pressure difference is large. Based on this concept, the exhaust pressure is adjusted based on the efficiency of the pressurizer, the temperature of the cooling water, etc. to generate electricity with high efficiency.
