%A Sadri, Somayyeh %A Rahmani, Fereshteh %D 2019 %T Novel technical and economic analysis of water and power co-generation in coastal areas %K water production, cogeneration, technical analysis, economic approach %X Analysis of the current status of power plants and finding solutions to increase their efficiency is essential because of longterm rising fuel prices, environmental concerns and an ever-increasing demand for energy in the world. A basic approach to maintaining the existing units is to increase energy efficiency by using these units in the cogeneration cycle, based on technical and economic considerations. In this paper, the technical and economic evaluation of a gas power plant in central Iran is used with reference to a combined electricity and freshwater generation system on Iran’s southern shores. Results show that the two gas turbines, a heat recovery boiler, condensing steam turbine and reverse osmosis unit at Chabahar is the most attractive scenario, because it has the highest net present value, internal rate of return, the quickest payback period and the lowest price in the studied scenarios. %U https://papers.itc.pw.edu.pl/index.php/JPT/article/view/1545 %J Journal of Power Technologies %0 Journal Article %P 209–217%V 99 %N 3 %@ 2083-4195 %8 2019-09-26
