  • the choice of the target level can thus be in the upper range of the respective evaporator tube, initially not filled with flow medium and as compensation space for the underlying column serving as a flow medium of the respective evaporator tube are sufficiently large can be chosen so that an exit is not evaporated Flow medium from the respective evaporator tube also beginning evaporation can be safely excluded.
  • Heating gas is advantageously the actual level of the respective Evaporator tubes adjusted to the specified target level.
  • the respective actual fill level is advantageously by means of a differential pressure measurement between the lower pipe inlet and top pipe outlet of the respective evaporator pipe determined, the measurement value obtained thereby expediently as the basis for feeding the respective evaporator tube with unevaporated flow medium becomes.
  • the start-up phase varies a particularly reliable compliance with the boundary conditions ensure that on the one hand an exit when starting of unevaporated flow medium from the evaporator tubes reliably excluded and on the other hand in everyone If sufficient cooling of all evaporator tubes is guaranteed should be the one for the first filling of the evaporator tubes relevant target level advantageously in Dependency on the intended start-up heating process specified.
  • the start-up heating process will expediently based on characteristic values for the boiler geometry and / or the course of the heat supply over time the heating gas is determined. It can be used for a variety of such Parameter combinations, each adapted start-up heating process in a database assigned to the steam generator be deposited, in particular also the current one Heating cycle previous heating cycles taken into account could be.
