Abstract :

Over the past 6 years, the country’s energy production has increased as much as 8.29% per year on the average. At the present time, power plants play a major role in the production of greenhouse gases and the optimization of the systems of the newly-constructed power plants is one of the country’s main environmental challenges. Therefore, the assessment of the construction of energy recovery systems aiming at increasing the efficiency of gas power plants with little pollution can be a great help to the environment. In this study, a techno-economic evaluation of energy recovery systems has been done in Kerman power plant considering air pollution reduction.   Fortunately, the potentials for the construction of combined cycle power plants exist in the country.   Since such power plants save the fuel and increase the efficiency, they can reduce contaminating gases. The application of energy recovery systems in gas power plants is quite economical and their pay-back rate is 9-10 years. The results of the present study show that with these plants, 152 million liters of gas-oil and 58.3 billion cubic meters of natural gas will be saved over a period of 30 years. As a result, 1.652 million tons of greenhouse gases will be reduced.
