Abstract

The water is supplied to further treatment stages and is subsequently condensed. The expansion of the heated water and purificn. of the resultant steam is carried out in the same appts. while the further treatment takes place in a Venturi washer in the satd. steam region and/or in a sepsepg. store. This ensures that the steam is free from the smallest mist particles contg. foreign, e.g. radioactive, material and the resultant steam is of highest purity even in the most unfavourable case of a heavily polluted effluent.
