Abstract

PURPOSE:To miniaturize a system available, by installing a two-phase flow generator in position between an evaporator and a turbine, in case of an open cycle marine temperature difference power generation. CONSTITUTION:Hot seawater 1 is deaerated at an deaerating chamber 2 and partially turned into steam by an evaporizer 3. Hot seawater 4 whose temperature gets dropped is exhausted outside. The steam enters a 2-phase flow generator 6. In this 2-phase flow generator 6, a liquid-drop group is produced and simultaneously a part of steam kinetic energy is given to this liquid-drop group. The 2-phase flow is made to increase intensity of its energy and provides an electric output to the external in such a way, as turning a generator 8 upon being led by a 2-phase flow turbine 7. The 2-phase flow, which has performed its job, is drawn into a condenser 9 and turned into a condensate water by an abyssal cooling sea-water 10. A part of the condensate water is returned to the 2-phase flow generator 6 by means of a pump 11. The rest is applied to other application purposes as a fresh water source.
