Review of Methods for Increasing Efficiency in Thermal Power Plants and Study of Shazand Power Plant

Power plants are one of the most energy intensive industries in our country. This paper reviews the most common methods for reduction of energy consumption and increasing of efficiency in power plants. For steam power plants, several methods have been presented to recover waste heat and water in water blowdown and for heat integration with solar energy. For gas and combined cycle power plants, change in conditions of inlet air to gas turbine, use of solar energy and steam injection system have been investigated. Also, the proposed procedures for steam power plants have been applied in Shazand power plant. The results showed that the efficiency increased compared to the base case.
