<p>The continuous steam generator (1) has a surrounding wall (2), which forms a gas draught (20) and whose lower section is configured from gas-tight evaporator tubes (6) that are welded together and whose upper section is configured from gas-tight superheater tubes (6') that are welded together. The superheater tubes are connected downstream of the evaporator tubes on a flow medium side by a water separator system (14). The water separator system has water separator elements (30) connected downstream or upstream to evaporator tubes.</p>
