PROBLEM TO BE SOLVED: To properly control the temperature and pressure of steam generated by the evaporator of a Rankine cycle device when an engine is started. SOLUTION: When the internal density of the evaporator is lower than a set value when the engine is started, the internal density of the evaporator is increased by increasing the supplied amount of water to rapidly converge the temperature of the steam to a target temperature and an expansion engine is stopped or controllably run at a very small speed near stoppage to prevent it from rotating to rapidly raise the pressure of the steam for starting the expansion engine. When the internal density is higher that the set value when the engine is started, the internal density of the evaporator is reduced by reducing the supplied amount of water to rapidly converge the temperature of the steam to the target temperature and the expansion engine is controllably run at a predetermined speed to efficiently discharge a liquid-phase working medium accumulated in the evaporator.
