ABSTRACT:
A steam turbine-generator power plant is described wherein solar energy is used to preheat feedwater to a steam generator. Two parallel feedwater supply branches are proposed for preheating the feedwater upstream from the steam generator. A first preheater branch utilizes extraction steam from the steam turbine for preheating feedwater and is called an extraction branch. A second preheater branch utilizes solar energy for preheating feedwater and is called a solar branch. The two branches are joined upstream from the steam generator and the proportion of flow from each branch is based on the temperature difference between the extraction branch and the solar branch. A variable speed pump is used to pump feedwater from the solar branch at a rate proportional to the temperature difference between the two branches.
