PURPOSE:To hold the overall balance of a system so as to stably collect driving power for the operational condition, in a wide range, of a concentration difference engine, by allowing a surplus flow of lean and rich solutions generated in accordance with a change of the operational condition to circulate bypassing a turbine or a pump. CONSTITUTION:Turbine-pump flow rate of Gt/Gp in a turbine pump 11 is set to a value almost equal to the minimum value of lean and rich solution flow ratio of Gw/Gs in the operational condition range of an engine, accordingly heght of the internal liquid level in a generator 1 tends to increase in accordance with rotation of the engine. However, the system is constituted such that a liquid level detector 16 detects the height of this liquid level to output a signal of the liquid level to a controller 17, controlling a flow path control valve 15 in a bypass flow path 14 and allowing a part of a lean solution to flow in the bypass flow path 14. In this way, the flow of the lean solution to a liquid turbine 12 of the turbine pump 11 is always controlled in an almost fixed level, the liquid turbine 12 is always driven by a flow at the maximum point of efficiency, thus the energy included in the lean solution at a high pressure is stably and surely collected and can be used as the power for driving a pump 13. |
