When you complete this lesson you will be able to explain how closed heat exchangers use extraction steam and latent heat to increase the temperature of the condensate and feedwater prior to entering the boiler. In addition, you will be able to describe how extraction steam and heater drains are used to increase the overall efficiency of the plant cycle.
