Abstract: This chapter deals with the theory behind power plants with particular reference to cogeneration and combined cycle power plants (CCPPs). The two key cycles are the Brayton (gas turbine) and Rankine (steam turbine) cycles, within each of which there are further subdivisions. A combination of the Brayton and Rankine cycles, often known

Natural gas combined cycle (NGCC) power plants are rapidly expanding worldwide to produce electricity due to various advantages compared with other types of gas power plants. The efficiency of NGCC plants ranges from 45 to 57%. Furthermore, carbon dioxide gas emissions from NGCC power plants are lower than those from coal-fired

Combined cycles correspond to this new generation of thermal power plants. Keywords: compression, expansion, combustion, combined cycle, HRSG, afterburner. The principle of a combined cycle is to operate in cascade one or more gas turbines, followed by a steam power plant whose heat source is the cold source of gas turbines (Figure 17.1.1).
