ABSTRACT:
In a steam condenser in which the steam is condensed on tubes (13) through which cooling water flows and which are combined in separate banks (20), each bank (20) being subdivided into compartments (10) by supporting plates (5) arranged perpendicularly to the tubes (13), a residual-steam/inert-gas mixture is drawn out of a precooler (2) via orifices (9) into an air cooler (3). The residual steam is condensed in the air cooler (3) and the collecting condensate (23) flows off on account of a slope of the air-cooler bottom (21) through a recess (18) to an adjacent compartment (10) having an air-cooler bottom (21) situated at a lower level. In this case, the condensate (23) flowing off from a compartment (10) situated at a higher level is retained at a retaining wall (22) on the air-cooler bottom (21) of the compartment (10) having the air-cooler bottom situated at the lowest level, this retaining wall (22) being arranged parallel to a supporting plate (5). Due to the retained condensate (23), the recesses (18) in the supporting plates for the condensate flow from a compartment (10) situated at a higher level can be closed hydraulically in both a gas-tight and a steam-tight manner.
