STEAM GENERATER IN RANKINE CYCLE ENGINE

摘要

PURPOSE:To eliminate an electric motor for operating a pump by a method wherein a liquid reservoir is arranged in the midway of a heat conductive pipe for the steam generating unit. CONSTITUTION:A liquid reservoir 14 is arranged in the midway of the heat conductive pipes 4a and 4b of the steam generating unit 4 which are divided into two and a large volume of operating or working fluid is remained in the steam generating unit 4 even if the Rankine cycle is stopped. Therefore, since the pressure required for starting operation of the system can be kept longer than a specified period of time even if the working fluid is not forcedly fed into the steam generating unit 4 in advance by the pump 5 when a temperature in the heat accumulater tank 3 is raised to restart the Rankine cylcle, it is possible to eliminate the electric motor 9 for operating the pump and to connect the pump 5 directly to the expansion device 6.
