The present innovation, on the other hand, has the task 2U-Grund «* the separation of the resulting steam «water« .MixB as well as the removal of the separated water directly into the outlet headers of the evaporator heating surface »,

To durchaufuhren such a gravity separation in the accumulator, even at high flow rates sure it is erforderliehf the flow velocity of the incoming steam-water Semi Sehes to shrink so _f that reliable separation into the liquid and the vapor phase enters "Heuerungsgemäß are for laterally completed in the collectors Built-in tubular body with a hollow seat on the steam duct

When exposed to much water it is expedient "that is * · built Röhrkörper are disposed of the same parallel to the axis of the collector in the upper part _f so that not yet been mixed with a sick possibly forming water level in the accumulator of the steam emerging with the water · It is also possible, however, to install the ear bodies at any angle to the collector axis * so that in the case of a renaissance the pipe bodies are arranged transversely or even perpendicular to the collector axis «

The flow velocity is determined by these tubular internals of the steam * water mixture is considerably reduced, since the available flow cross-section in this tubular body is considerably larger than in the feed line through which the flow was previously flowing This results in a safe separation of the mixture *

In this collector, according to the illustrated embodiment, tubular fittings 5 are provided parallel to the axis of the same, the end faces 6 and 7 of which are closed and the side facing the vapor discharge line 4 has a longitudinal slot 8 until the mixture feed lines 2 open radially into this hollow body 5 ei & * Sie Iiättgssehlitg © $ the pipe bodies 5 are attached at an angle to the axis of the 4-way supply line, so that a direct flow passage through the termies and an additional deflection is achieved.

Now the supplied steam / water mixture enters the pipe body 5 via the supply lines 2, the available flow crossover increases, so that the flow speed of the mixture is considerably reduced The flow direction is deflected to the described laterally attached Mngsschlitzen 8, a safe separation of the steam or water- like phase takes place so that the water runs down into the collector 1, while the steam flows into the upper area and is discharged there via the steam discharge lines.

In the design of such collectors, it turned out to be water-steam racing vessels proved to be sufficient # if the number of water discharge lines 3 is less than that of the steam discharge

With the design of the collector described as a gravity separator for the water carried along in the steam tank, considerable cost savings result from the saving of the previously customary "very expensive water" steam race vessels behind the evaporator required »to enlarge the actual collector in volume * but it is completely sufficient to provide the previously usual collectors with the drill bits described *
