Abstract

A preheater 1 for feedwater in steam power plants, with a vertical heat exchange vessel 2 with U-shaped tubes. These are divided into two groups 9a and 9b, respectively. The group 9a passes downwards through a drain cooler shaft 13 and bends back at the bottom of the vessel 2. The other group has less length and bends back at a considerable height above a condenser surface 15 such that between this surface 15 and the group of tubes 9b, a tube-free space 7 is formed, which is utilised as a flashbox. <IMAGE>
