Abstract:
1. A method for operating a steam generator, comprising: arranging a continuous heating panel of an evaporator in a heating gas channel that is cross-flown in a substantially horizontal direction of a heating gas, comprising; a plurality of pipes of a steam generator are connected in parallel to each other and are constructed such that they cross a flow medium and are provided with a portion of a substantially vertical down pipe that can be cross-flown by a flow medium in a downward direction and with the part of a riser pipe connected downstream with respect to the down pipe on a flow medium side and is substantially vertical and can be cross-flown by the flow medium in an upward direction and the continuous heating panel of the evaporator is arranged such that one pipe of the steam generator that is hotter than an other pipe of the steam generator of the same continuous heating panel of the evaporator has a flow medium rate that is higher than that of the other pipe of the steam generator, wherein the flow medium of the continuous heating panel of the evaporator is supplied in such a way that the flow medium in the part of the down pipe of the specific pipe of the steam generator has a flow velocity which is higher than a minimum flow velocity predefined in the down pipe.
