CLASS 14: Steam Engines.

Patented in the German Empire on January 11, 1885.

The present construction is intended for refrigerators, which are used to represent Serve fresh water through the condensation of water vapor and especially on seagoing vessels to be used.

The channels used for condensing are arranged in such a way that they are used for cooling the steam water flowing through have a large surface. The arrangement of each Part is such that the apparatus can easily be taken apart, too in construction, care is taken that the individual parts expand and move in together.

The attached drawings show:

Fig. Ι a vertical section through the apparatus,

2 shows a vertical section through a condensation and cooling tube;

Fig. 3 and 4 are cross sections along the lines xx respectively. \ - \ of Fig. 1;

Figures 5 and 6 illustrate two other constructions of condensing and cooling tubes.

The tubes, in the construction of which the essence of the invention consists, are arranged between the upper partition ^ and the lower partition g and are fastened to these walls with their upper and lower ends. These ends formed by the T-shaped pipe sections e are connected to the partition walls at the bottom by the nuts k and at the top by the nuts h.

The partitions / and g are corrugated in the shape of a ring, as indicated in the cross section at f ¹ and g · ¹ , so that when the tubes expand and contract, these walls spring and allow the tubes to change due to the change in temperature. The walls mentioned close the cylinder A ₁ surrounding the pipes, which serves to circulate the cooling water through channels D and E , at the top and bottom. The upper wall / is held by bolts /, Fig. 1, between the upper flange of the cylinder A and that of the steam chamber B, which forms the cover of the apparatus. The lower partition g is also held between the flange of the cylinder A and that of the filter box C by bolts.

The cylinder A for the circulation of the cooling water, the steam chamber B and the filter box are of the usual construction.

The cooling water flows through the opening D into the cylinder A and through the opening E out of the same. The steam chamber B communicates with the steam pipe at F. The filter box C contains the filter H and is connected at the bottom with the outlet pipe J for the condensed and cooled water and at the top with the air pipe L. The purpose of the latter is to let the air flow into the fresh water flowing through the cooling pipes into the filter box.

The ways in which the steam from the steam chamber B is conducted by means of the cooling pipes to the filter box C consist of helical channels a, which can be constructed in various ways, as FIGS. 2, 5 and 6 show.

In these three types of tubes, the channels are located between an inner tube b ¹ and an outer tube b. These

Pipes are best made of copper sheet, are soldered together at the ends or sealed together and in some other way. ■ allow on the one hand the entering steam access and on the other hand the draining water exit from the helical channels α by means of the T-shaped pipe pieces ee, whose branch ^{pipes e 1} e ¹ communicate with the channels α , while the vertical legs of the same are threaded at the end and are connected to the partitions ^^ ", as already described.

The channels α are either, as in Fig. 2 and 5, formed by the pressed into the tube b , winding and the wall of the inner tube b ¹ touching grooves or trains d or, as in Fig. 6, by winding, between the Pipes b and b ¹ inserted wires d, which lie tightly against the pipe walls on the outside and inside. In the pipe in Fig. 2, “only the outer copper pipe b is provided with these trains d, while in the pipe in Fig. 5 both the outer pipe b and the inner pipe b ^{1 have} such helically wound trains d , only the direction of rotation is opposed to it, so that the steam to be condensed flows partly to the right and partly to the left over the surface of the inner tube b ¹ .

When the apparatus is started up, cold water is circulated in the cylinder A and around the outside of the channels α of the condensation and cooling pipes. The steam flowing out of the generator is passed through F into the steam chamber B, from where it flows through the pipes ee ¹ into the channels α in order to condense in the same. The steam water cools down by flowing through the lower part of the channels α and finally passes through the lower pipe sections e into the filter box C, from which it is pumped through the pipe J for use.

The steam as well as the steam water are, in that they pass through the helically wound channels α in a single flow, as in the pipes in FIGS. 2 and 6, or in two intersecting flows, as in FIG. 5, for a longer time Contact with the surface of these channels, which is constantly cooled by the water circulating in cylinder A.
