Abstract
A power plant is suggested with an additional heat transfer between the flue gas that flows through a flue gas line (5) and the feed-water in a feed-water line (19). The claimed arrangement of the first heat exchanger (13) upstream and adjacent to a precipitator (7) leads to a reduced space demand and optimizes dust precipitation as well as the pressure drop of the flue gas.
