| Research Abstract |
In this study, a novel type of cooling water system for thermal power plant is proposed, that is, the cooling water would be contained in a closed circuit pipe system and circulated between cold regions of the deep water and the condenser for turbine steam cooling. As a result of the case study on the new system applying to 100 MW class thermal power plant, the gain of power would be available up to 2.5% if the drag reduction is achieved with adding surfactant to circulated cooling water, and when the system is designed properly. And the outlines of new pipe laying method and sub-sea heat exchanger are described. Moreover, the possibility of fertilizing the sea with use of upwelling due to the input of heat via sub-sea heat exchanger is investigated.
