Steam dryer for low pressure steam boilers

The innovation relates to steam dryers for low-pressure steam boilers, For example, for low-pressure steam generation in gardening businesses for steaming, i.e. sterilizing potting soil can be used and are either stationary or mobile.

A disadvantage of the low-pressure steam boiler has been that when the water content of the boiler boils, water splashes into the Steam outlet line was carried away, affecting the overall operation of the boiler had an adverse effect. About being carried away by splashing water To avoid this, the water level in the boiler had to be correspondingly low be held so that the efficiency of the boiler was reduced. -

It is the task of the innovation to eliminate this disadvantage and to create a steam dryer through a simple structural design, which allows a higher filling of the boiler and ensures a higher ■ efficiency.

A steam dryer for a low pressure steam boiler is according to the innovation characterized in that a housing closed on all sides is welded to the upper part of the boiler until in the upper half of which protrudes a steam pipe of the boiler, which from a dome-shaped, closed at the top and open at the bottom Splash water catcher is surrounded all around at a distance that on A splash water return pipe is connected to the bottom of the housing, which extends to the lower part of the SsHpisfeEHsküSEgskMüHSS low-pressure steam boiler is performed, and that at the upper end of the steam dryer housing a steam outlet pipe leading to a steam superheater connected.

It is also essential that the cross section of the steam pipe Many times larger than the cross-section of the spray water return pipe it is.

The splash water return pipe can be inside or also outside of the boiler in the lower part of the same.

One embodiment of the steam dryer according to the invention is shown schematically in the drawing. Mg. 1 shows a longitudinal section of part of a lying low-pressure

Steam boiler with attached steam dryer. Fig. 2 shows a schematic cross section.

The steam dryer consists of a housing 1, which is on all sides is closed and is placed on the upper part of the steam boiler 2. The bottom 3 of the housing 1 is at a distance from the jacket of the boiler 2 arranged. A steam pipe leads through the bottom 3 4 from boiler 2 to the upper half of housing 1. A hood-shaped splash guard 5 is spaced on all sides "Put" over the steam pipe, so to speak, so that spray water carried along by the steam rising in the steam pipe 4 on the wall of the splash water catcher 5 expires and collects on the bottom 3. From there it is returned to the lower part of the boiler 2 through a spray water return pipe 6. The one freed from splash water Steam emerges from the housing 1 of the steam dryer through a steam outlet pipe 7, which leads to a steam superheater (not shown) running through the combustion chamber 8 of the boiler 2.

By providing the steam dryer, the water level 9 in the Boiler 2 are kept very high, so that a good efficiency is achieved.

In Fig. 2 is the spray water return pipe 6 within the Kessel 2 relocated. It can of course also be guided along the outside of the boiler 2. But it is essential that the spray water return pipe 6 extends into the lower part of the boiler and that its cross section is considerably smaller than that of the steam pipe 4, so that no water can rise in the spray water return pipe 6 due to the pressure conditions thereby given.

The low-pressure steam boiler 2 is, for example, by a Heated oil atomizer burner. In FIG. 2, the heating gas pipes 10 are of the boiler 2, which have been omitted in Fig. 1 for the sake of simplicity. Of course, is the low-pressure steam boiler 2 with fittings prescribed for such devices and Provide safety devices that are not part of the innovation and are therefore not described in detail.
