Function of condenser in a feed system for boiler and steam turbine ; The condenser is a heat exchanger which removes the latent heat from exhaust steam so that it condenses and can be pumped back into the boiler. The feed system completes the cycle between boiler and turbine to enable the exhausted steam to return to the boiler as feedwater.
