兩種以上的熱機學原理的組合。一組布萊頓循環(氣渦輪機/燃氣引擎)和一組朗肯循環(汽渦輪機/鍋爐)。將第一段循環的煙氣熱損失由後續的循環轉變為有用的能量(Combined cycle: combination of two or more thermodynamic cycles, e.g. a Brayton cycle (gas turbine/combustion engine) with a Rankine cycle (steam turbine/boiler), to convert heat loss from the flue-gas of the first cycle to useful energy by subsequent cycle(s))
