PROBLEM TO BE SOLVED: To provide a binary power generation system in which cold with ultra low temperature which LNG has, is collected for using the cold as a cold source, and a binary cycle in which the cold is combined with other heat source with high temperature, is assembled.SOLUTION: Alternative flon or the like is employed as a working fluid, and ultra low temperature of LNG is utilized for performing cooling and liquifaction of the flon to low temperature about minus dozens of °C and low pressure in a vacuum area. After pressure is raised by a pump 2, the alternative flon is subjected to vaporization and heating by sea water and a high temperature heat source related to a main machine, for making overheated gas. A turbine 14 is driven for rotating a power generator 15 directly connected thereto, for taking out power. On a condenser 21 in the vacuum area, air immersion is prevented by a double structure of the condenser in which the working fluid is filled in the surrounding. The working fluid with low temperature is temperature raised by sea water in advance, for preventing condensation and creation of moisture and sulfur oxide. The LNG fluid is compressed and then serves as a cooling source of the working fluid of the binary system, and at the same time, the LNG fluid is subjected to vaporization and heating by the heat source related to the main machine, for making overheated gas, for rotating a turbine 42 for generating power, similarly.

    【課題】LNGが有する超低温の冷熱を回収して冷熱源とし、別の高温の熱源と組み合わせたバイナリーサイクルを組み立てたバイナリー発電システムを提供する。【解決手段】作動流体として代替フロン等を採用し、これをLNGの超低温を活用して、マイナス数10℃の低温且つ真空領域の低圧まで冷却と液化を行い、ポンプ2によって昇圧した後に海水と主機関連の高温熱源によって気化・加熱して過熱ガスにし、タービン14を駆動して、直結の発電機15を回転させて電力を取り出す。真空領域となる凝縮器21では作動流体を周囲に充満した2重構造として空気の侵入を防ぐ。低温の作動流体は予め海水によって昇温して、加熱ガス中の水分や硫黄酸化物の凝縮と生成を防いでいる。LNG液は加圧した後にバイナリーシステムの作動流体の冷却源となると同時に、主機関連の熱源で気化・昇温し過熱ガスとしてタービン42を回し同様に発電を行う。【選択図】図3
