Assumptions :
1- Mass flow rate enters RSCC = 1Mkg/hr (277.78 kg/s) .
2- Wind velocity =1 m/s.
2
3- Heat transfer coefficient h out = 10 W/m K.
4- Heat loss in pipes neglectable .
5- Pressure difference between each stage 1.5 bar .
6- The domain of salinity we working with does not have effect of flow and
boiling temperature .( Appendix A3)[14]
The energy balance equation based on the first law of thermodynamics needs to
rise the brine temperature from 41° c to 110° c is :

= . . ( – ) (3.1)
= 277.78 * 3800 (110-41)
= 72.83 MW
Solar collectors calculations :
In this project, the module of the LS-2 PTC [1,2,3] is used in order to gain the
required energy to heat brine water. it is illustrated in Figure 1a.
