2. Recovery boilers
At the design stage, performance gains on combined-cycle power plants are mainly achieved on the water-steam cycle. For a given power level, the choice of gas cycle often results in the same machines (standardized combustion turbine), hence the importance of the steam cycle to distinguish solutions.
This cycle corresponds to the Hirn cycle.
2.1 General presentation
The recovery boiler is the component of the combined cycle that links the gas cycle and the water-steam cycle. The improved performance of combined cycles is certainly linked to technological advances in combustion turbines and steam turbines, but also to developments in boilers (increased energy recovery from combustion turbine exhaust gases, more complex positioning of...
