Multi-part heating tube boiler with high performance

The invention relates to a heating tube boiler of high power for generating superheated water, the structure of which is a
Road transport permitted in one or more elements.

The weight and dimensions of the known high performance boiler do not allow road transport, so that a
costly assembly required in final location
that does not have the quality of work done in the factory. The construction on site also delays the date for commissioning, as this can only begin after completion by the heating engineers.

The heating tube boiler according to the invention does not have these disadvantages and has the following features:

- The boiler can be built in one piece while remaining within the dimensions of the street dimensions.

- To facilitate its transport, its installation and
it can be divided into several elements to reduce transport and installation costs.

- It consists of a combustion chamber that can be divided into two parts and behind which the convection beams and
if necessary, a built-in preheater are arranged, the
can be transported in one or two elements.

- These elements are connected to each other by two welds
connected, which are very easily accessible on the upper collecting chambers.

The boiler according to the invention, in particular a combustion chamber and has an in-line convection bundle, the combustion chamber and the convection bundle forming pipes with at least two longitudinal collecting chambers are connected, is characterized in that the longitudinal collection chambers consist of several parts welded together.

According to a modification, the longitudinal collecting chambers consist of three parts, the combustion chamber, the convection bundle and
correspond to a preheater arranged in its extension.

According to a preferred embodiment, the longitudinal collecting chambers exist the combustion chamber consists of two parts.

Regardless of the number of parts of the longitudinal collecting chambers, a divisible heating tube boiler for generating superheated water is obtained in this way, of which all elements, which are preferably one behind the other in a line, have a direct one
Allow smoke evacuation without unnecessary pressure loss, whereby

a good, evenly distributed heat exchange and a good equilibrium of expansion is achieved.

Further features and gate parts of the invention emerge from dee The following description of an exemplary embodiment, reference being made to the accompanying drawing.

Fig. 1 is a section through the heating tube boiler along the line 1-1 of Fig. 2,

FIG. 2 is a plan view of the heating tube boiler, one half of which is cut along the line 2-2 of FIG. 1,

Fig. 3 is a section along the line 3-3 of Fig. 1, and FIG. 4 shows a section along the line 4-4 of FIG. 1.

1 shows the combustion chamber 1, the convection bundle 6 and the preheater 12. The combustion chamber 1 can be divided by the cuts 2 into two elements, the top and bottom be made on the longitudinal collecting chambers 3 between the two transverse collecting chambers 4 and 5.

The convection bundle 6 consists of upper and lower transverse collecting chambers, to which the vertical water pipes 9 are welded, which form the Konvektion3 heat exchange surface. The longitudinal collection chambers 3 are cut at section 10 and are provided with welded-on bottoms. They are split at 11 to am To be welded easily accessible location.

The preheater 12 consists of discontinuous finned tubes 13 » which are welded to four vertical collecting chambers 14. It is fed via the connection 15. The two lower collecting chambers 3 are divided at 17 and provided with two full floors. The two upper collecting chambers 3 are divided at 16

609827/0204

and are connected to one another by an easily accessible weld after assembly on site.

To further reduce the dimensions of the heating tube boiler, the flanges 19 are embedded in the thermal insulation jacket, so that the transport height of the heating tube boiler is reduced.

Fig. 2 shows the combustion chamber 1, the longitudinal collecting chambers 3 » the transverse collection chambers 4- and 5 »between which the cut is located is located, as well as the cut 10 between the combustion chamber and the convection bundle 6 and the cut 17 between the convection bundle 6 and the preheater 12. On the top is the nozzle 15 for the water inlet and the nozzle 18 for Water leakage. The tubes 20 of the side walls of the combustion chamber are outwardly deformed at 21, so that the combustion chamber is maximally widened and facilitated the expansion will.

In FIG. 3, which shows a section through the convection bundle, the longitudinal collecting chambers 3 are shown, on which the transverse collecting chambers 7 and 8 are welded on. The tubes 9 forming the convection surface are welded to these.

In Fig. 4, which shows a section through the built-in preheater, the longitudinal collecting chambers 3 are shown, where the vertical collecting chambers 14- are welded, which are fed via the nozzle 15 and between which the finned tubes 13 are mounted, which the thermal heat exchange surface of the Form preheater. The circulation of the water is rational: entry of the water on the side of the coldest smoke and Exit on the side of the hottest smoke.

From the description, in particular from FIG. 1, it can be seen that the heating tube boiler is based on the embodiment shown consists of four parts, namely:

609827/0204

a part corresponding to the front half of the combustion chamber with four longitudinal collecting chambers, a part corresponding to the rear half of the combustion chamber with four longitudinal collecting chambers, a part corresponding to the convection bundle delimited by four longitudinal collecting chambers, and a part that corresponds to the preheater, which also has four longitudinal collecting chambers

The individual longitudinal collecting chambers are butted together so that they can easily be combined to form a high-performance boiler can be welded.

Depending on the output and thus the size of the boiler, it is thus possible to use a more or less large number of longitudinal * collecting chamber parts to be provided

The invention thus allows the manufacture of very high performance boilers from independently manufactured ones Elements that are particularly easy to assemble because they are assembled from a weld the longitudinal collecting chambers, which are arranged on the circumference of the boiler and can thus be easily reached.

The invention is not limited to the embodiment described above limited, but allows changes, in particular the invention is also applicable to boilers for generating saturated or superheated steam.
