1. A method of starting a continuous steam generator, comprising:
providing a combustion chamber comprising a plurality of burners, a water-steam separation device being arranged downstream of a plurality of evaporator tubes of the combustion chamber on a flow medium side, and a plurality of superheater tubes arranged downstream of both the plurality of evaporator tubes and the water-steam separation device; measuring by a sensor a value of a fill level of water-steam separation device;
adjusting a firing power of at least one of the burners by a control unit as a function of a value of the fill level of water for the water-steam separation device to minimize the water quantity flowing into the water-steam separation device during a starting process,
wherein the firing power is adjusted as a function of a change in speed of the value of the fill level such that the firing power is adjusted when the value of the fill level is increasing, and
wherein the water is a result of water discharge due to incipient evaporation.
