Abstract

In a regenerative high-pressure feedwater preheater of upright construction with a U-shaped tube bank (9, 10), with built-in heat removal zone (4), with integrated, submerged undercooling zone (18) and with a water chamber (27, 28) lying below, the heat removal zone and the undercooling zone are each shielded with a cover (6 and 20 respectively) against the condensation zone. In the heat removal zone (4), a chamber (23), which is not flowed through by vapour, is arranged around the tube bank (10). <IMAGE>
