Abstract
In a process for preheating and deaerating make-up water in a power generation plant by steam, the required make-up water is initially heated up to the saturation temperature without substantial deaeration and is subsequently deaerated. The steam used for heating and deaerating is expanded steam from a condenser, which steam is almost fully condensed during the heating of the make-up water and is recycled to the steam circulation of the power generation plant.
