Abstract
The invention relates to a steam generator wherein a continuous heating panel of a generator, which is formed from a number of evaporator tubes, and an overheating panel, which is formed from a number of over-heating tubes which are arranged downstream from the evaporator tubes and on the flow side, are arranged in a heating gas channel. According to the invention, a water separating element is integrated into a number of over-flow tubes which are connected on the flow side of one of several evaporator tubes to one or several overheating tubes.
Claims9
A steam generator, comprising:
- an evaporator once-through heating surface formed from a plurality of evaporator tubes;
- a superheater heating surface arranged in a heating gas side of a heating gas passage and faulted from a plurality of superheater tubes connected downstream of the evaporator tubes with respect to a flow medium;
- a plurality of water separation elements each attached to an overflow tube section that connects the evaporator tubes to the superheater tubes with respect to a flow medium,
- wherein the water separator element comprises an inflow tube section connected to the evaporator tubes which are connected upstream of the water separator element and the inflow tube section, as seen in its longitudinal direction, merges into a water discharge tube section, and
- wherein the water separator element also comprises a plurality of outflow tube sections, connected to the superheater tubes which are connected downstream of the water separator element, branching off in a transition region between the inflow tube section and the outflow tube section.
