Inside Station B of the Wairakei Power Station showing a Mixed Pressure steam turbine. The steam turbine is grey and red with two steam control valves infront of it. The generator is light green and its exciter is smaller and to the far right. The most striking feature is the bright green and massive condenser beneath the turbine. It is this condenser that makes such turbines economic, efficent and workable. Waikato River water enters the condenser through the two central pipes and is sprayed into the steam to cool it, creating a vacuum that pulls the low pressure steam through the turbine - Image: Heurisko Ltd.
