Abstract
In this research, a mathematical model was created to study the performance of the development of basic design of dual electro thermal centers dedicated to the production of electric energy and desalinated water together. In the form of a measure of the effectiveness of the heat and maintaining the lowest level of pollution of the surrounding medium , for electricity and desalinated water together , in the proposed design compared to the independent production of electric power and desalinated water through a processing plant and reverse osmosis desalination unit .The effect of multi-effect evaporated desalination unit and the gas turbine unit , as well as the thermodynamic thermal properties of this unit , were compared with the basic design of the steam plant . The result of the study has been shown:
The effectiveness of using dual-pressure double –phase in the development of steam station to the centers of electro thermal. Where the minimum savings in the amount of fuel consumed 77.9 kg/hr to MW (Mega Watt ) .of electric energy produced in the basic design of the steam plant and the lower resulting pollution rates such as a nitrous oxide( 0.26 kg/MW.hr ) , and carbon dioxide present in the air pressure supplied to the desalination unit from 0.3 bar ,( as result of this improvement , the design number of the effects of desalination unit =8 ,and the water quantity produced 15.7 ton/MW.hr ) .
High pressure steam supplied to the desalination unit from 0.3 bar to 0.38 bar, and the high quantity of desalination water produced by 15.3 %, as well as decrease in the electric power produced by the steam turbine unit ay rate of 2.9 %.
Thermal and environment performance of the use of successive gas turbine unit in the development of steam turbine to the centers of electro thermal ,where the lowest level of increase by the amount of fuel consumed and environment indicators above 14.9 %.
