Abstract

In a process for starting a continuous steam generator (1), through the evaporator tubes (4) of which water flows on the supply side from bottom to top, in order to prevent starting losses at least some of the water discharged from the evaporator tubes (4) on the outlet side is fed back into the inlet side. To this end there is a starting system with a discharge line (44) connecting the evaporator outlet (10) to the evaporator inlet (8).
