Basic combined cycle
The thermodynamic cycle of the basic combined cycle consists of two power-plant cycles. One is the Joule, or Brayton, cycle, which is a gas-turbine cycle, and the other is the Rankine cycle, which is a steam-turbine cycle. The cycle 1–2–3–4–1, which is the gas turbine power plant cycle, is the topping cycle. It depicts the heat- and work-transfer process taking place in the high-temperature region.
