Today, the energy problem is one of the most important issues that the world needs and needs to be solved. Since combined cycle power plants also have advantages such as efficiency, high power and ease of operation, the establishment of these types of power plants attracted investors and caused them to have a large share among electricity generation facilities in recent years. While the efficiency in a simple cycle power plant is between 35% and 40%, the efficiency in combined cycle power plants has reached 60% with today’s technology.
