Description

Steam generating plant. The invention relates to steam generation systems, especially one with several symmetrical to a central combustion chamber arranged evaporator, superheater and preheater elements in the heating gas flow lying one behind the other.

The purpose of the invention is to be simple and cheap in construction To create steam generating plant to be produced, in which in extremely cheaper Way both the space and the heat supplied by the fuel are used will.

This is achieved essentially according to the invention in that the Heizelenientegruppen are arranged to each other that they the combustion chamber Enclose in the plan on all sides without any gaps.

On the accompanying drawing; is a steam generating system according to the Embodiment shown, for example, and Fig. I is a plan view of a System with three groups of evaporation elements, Fig. 2 a vertical rolled up Section along line i-i of Fig. I, Fig. 3 a section along line 2-2 of Fig. I, Fig.4 a vertical section on an enlarged scale through an evaporation tube bundle one of the three groups of evaporation elements, Fig. 5 a vertical section, also on a larger scale, by a bundle. of preheater pipes for the feed water one of the three groups of evaporation elements.

The system consists of three batteries or groups of Evaporation elements or from standing boiler tubes with fixed or removable ones Circulation pipes.

Each of the three steam generators I, II, III consists of a bundle of Boiler tubes A, a water and steam tank B, a superheater bundle C and a Preheater bundle D for the feed water. The whole thing is in an outer coat E.

Each individual evaporation bundle _ 1 (Fig. 4) consists in turn from one or more functional horizontal chambers a, with which the removable boiler pipes b are connected. The box-like chambers are horizontal Direction divided into two compartments by a partition c, so that the one in each Boiler tubes b developed steam into the upper compartment and from there into the steam container B arrives.

The boiler pipes are fed with water through the pipes b 'opening into the lower compartments of the chambers a, which is fed from the container B through pipes f .

To facilitate the outflow of steam from the chambers a, is an opening g is provided in the partition wall c through which the upper Compartment water carried away by the steam immediately into the lower compartment and from there can flow into the tubes b '.

On the chambers a, shorter tubes b ″ are attached to the bottom wall the chambers a to protect against the heat and to prevent their warping.

The boiler tube bundles lie in a jacket F, with three on top of each other arranged openings F '(Fig. i) for the passage of the coming from the boiler pipes Gases is provided. These divide into two streams, the superheater C and the Flush preheating pipes D and then flow into the smoke pipes G, all of which have a common, not shown chimney are connected.

The pre-heaters D (Fig. 5), like the pre-steamers, consist of two concentric ones Pipes h-1 'which open into two-part chambers i corresponding to the boiler pipe chambers.

Fig.3 shows the path taken by the gases, the steam and the water, recognize.

In the upper part H of the combustion chamber is the powdery, solid or liquid fuel is introduced while the ash is removed at the lower end H ' will.

The saturated steam developed in the boiler tube bundle A passes through the connecting tubes c into the container B, from there through the lines j into the collecting tube k and is fed through six tubes L to the six top heaters C.

The superheaters C consist of vertical coiled pipes with uniform Collector. The circulation of the steam: takes place in countercurrent to the one passing through the superheater Gases. The superheated steam leaves the Berliitzer through six lines lead to a common pipe v with the drain cock o for the steam. That Feed water is at p in a collecting pipe, which through six lines q the six Preheater D supplied, pressed. After heating, it flows through the lines r in the containers B.

To completely empty the boiler tube bundle A and the preheater D while maintaining the possibility of unhindered expansion of the tubes, the ends of these flexible lines carry s, which are connected to two manifolds t and zi for the boiler tubes and for the preheater. To completely empty the entire system, it is sufficient to open the two taps v and w.

Claims (3)
