  • The Water-Steam Cycle

    The gas exhaust flue supplies heat to the HRSG, where it is used to generate steam. The vapour travels from the HRSG via pressurised pipelines where it is used to drive three sections of the Steam Turbine. This process converts the thermal energy of the steam into kinetic (rotational) energy which is sent by a fixed shaft to the Electrical Generator to be then converted into electrical energy. The fixed shaft arrangement is illustrated opposite.

    Once the vapour has fully passed through the blades of the turbine it enters the Condenser section where it undergoes a change of state back into water. This liquid form can then be efficiently re-sent to the HRSG so as to continue the Water-Steam Cycle.
