Abstract:
This paper presents thermodynamic simulation, economic modeling and annual profit optimization of a multi generation system which produces both power and fresh water. The fuel of the combined system is natural gas plus synthesis gas which is produced in biomass gasification reactor. In order to evaluate thermodynamic performance of the biomass gasification reactor, visual simulation software was developed in C# programming language. The multi generation system is analyzed both with inlet air cooling and without inlet air cooling. The final results show that the total cost of produced power is ۰.۰۲۸۶ /kWh and total cost of produced water is ۰.۷۴۰۸۲۸۶ /m۳. Also the total annual profit which comes from selling power and water to the market is ۳۵.۱۰۳ M and the CHP efficiency is ۶۷.۰۸. Optimization of the configuration is carried out once the simulation phase is finished. The optimization results in ۱۰.۵% increase in total annual profit and ۶.۶% increase in CHP efficiency.
