Description

Device for dewatering the steam in steep tube boilers. The subject the invention forms a device for dewatering the steam in steep tube boilers with steam collector arranged behind the upper boiler.

In steep tube boilers with only two drums, i. H. an upper and a lower drum, it can happen that with high steam output water from the boiler is entrained into the steam line.

With high steam output, the water level becomes unsteady, and the Breakthrough steam takes water finitely after the steam collector. On the way and Some of the water will be excreted in your steam collector. This excreted Water flows back to the upper boiler. The returning water flows so the rising steam and this takes it over and over again above. So the water cannot separate.

The purpose of the invention is now to eliminate this disadvantage, and this happens primarily because of the fact that on your steam path from the upper boiler until a water collector is switched on. To lead back here to enable the excreted water in the water collector, this can through special pipes are connected to the steep-tube lower or upper boiler.

The drawing shows an embodiment of the subject matter of the invention shown.

It denotes a the upper boiler, e the lower boiler and c the water collector. The latter is advantageously arranged at the same height as the upper boiler a and is connected to it through one or more pipes b. The pipe (s) b initially go vertically to o'-en, then bend into the horizontal right and enter the water collector c in the direction from top to bottom. For example, water entrained by the steam flowing from the upper boiler into the water collector c retains the direction of flow from top to bottom when entering the water collector and collects at the bottom of the water collector, while the steam flows through pipes d to a steam collector g and from here in the line flows. The separation of water and steam is, as a result of this arrangement, a much better ace so far, because the much heavier water does not change the direction once it entered the water collector and falls to the ground and separates from the steam, which changes its direction slightly. This water, which collects at the bottom of the water collector c, can be fed back into the lower boiler e through pipes f. If the water collector c is arranged somewhat higher than the upper boiler tt, the pipes f can also be led to the upper boiler a so that the separated water flows to it. In other respects, too, the most varied of modifications can be made in the structural direction without falling outside the scope of the invention, provided that the arrangement is such that a water collector is connected in the path of the steam between the upper boiler and the steam collector, in which steam and water are forced to separate.
