Abstract
An integrated system in which the required steam of multi effect distillation (MED) desalination, used for producing potable water, is provided by using the waste heat of a high-capacity wind turbine (WT). This system is used in the areas with shortage of potable water supplies and high wind energy potential. In addition, energy, exergy and thermoeconomic analysis are performed. The results revealed that in the areas with average wind speed of 11â¯m/s, the waste heat in a 7580â¯kW WT is 231â¯kW at 140â¯Â°C. The produced steam at 100â¯Â°C and 101.3â¯kPa is enough to produce 45.069â¯m3/day potable water, which is sufficient for the daily use of 4507 people if each person consumes 10â¯L. Furthermore, the findings indicated that the maximum exergy destruction and exergy destruction cost are related to the second effect of MED desalination. Also, the cost of potable water is estimated as 16.676â¯$/m3. Using the waste heat of the WT increases the exergy efficiency of the integrated system 7.34%. Considering the cost of potable water, average rate of return and payback period are estimated as 6.76% and 6.33â¯years, respectively.
