Description

Steam locomotive with condensation.

The invention relates to steam locomotives with condensation and aims to reduce the feedwater losses of the locomotive to a particularly advantageous one Way to balance.

The advantages of condensation can only then be used in locomotives If it is made possible, the inevitable feedwater losses are eliminated Replace the supply of purified feed water to the locomotive boiler. The required However, the amount of purified feed water cannot be carried with condensation locomotives because the necessary to suppress the vapor in the condenser are large Water quantities and the dry cooler all available space on the tender and the locomotive take away; Furthermore, purified feed water is not available at the intermediate stations. The invention makes practical operation challenged by these circumstances of condensation locomotives possible by the fact that they the locomotive boiler with a for the intake of raw water serving additional boiler connects, which except for the Train heating is able to deliver a further amount of steam required by the steam train, whose condensate is sufficient to cover the feedwater losses.

In the drawing, Fig. 1 shows the relevant parts of a Embodiment of the object of the invention in side view, Fig. 2 the eligible parts of a second embodiment in side view, partially in section, Fig. 3 shows a third embodiment in one of Fig. I. corresponding representation, Fig. 4 a section according to 4-4 of Fig. 3, from the left seen, Fig. 5 is a representation of a fourth embodiment corresponding to Fig. 4, Fig. 6 a fifth embodiment in longitudinal section through the locomotive boiler, Fig. 7 is a cross-section to Fig. 6 and Fig. 8 is a section on a larger scale after 8-8 of Fig. 7, seen from the left.

First of all, the embodiment illustrated in FIG to be discribed.

In the smoke chamber at of the locomotive boiler A is an additional boiler B used, which is provided with two nozzles bl and b2.

The connection bl is in with a (not shown) feed pump Connection that supplies boiler B with not particularly purified feed water from a Container feeds. The connection piece b- 'is to the heating line and to another secondary consumption point connected.

The feed of the additional boiler can, as the water evaporated in it either not recovered or returned to the boiler in the form of condensate is supplied, take place with raw water. It is therefore necessary to cover the feedwater losses the locomotive boiler only has a relatively small supply of purified feed water to be carried.

In the embodiment shown in Fig. 2, the auxiliary boiler B inserted into the standing boiler a2 of the locomotive boiler, in such a way that its heating takes place both by steam and water and by the fire gases of the fire box a3.

In the example shown in Fig. 3 and 4, the additional boiler is located B on top of the long boiler A of the locomotive. The heating is done by boiler steam, which is fed through a pipe b3 (Fig. 4) to the additional boiler B and in a heating coil M is partly knocked down. The condensate flows into the boiler through a pipe b back to.

In the embodiment illustrated in Fig. 5 is sufficient Additional boiler B into the steam and water space of the long boiler A so that this increases its heating surface. However, the additional boiler only extends so far into the long boiler that the condensate formed in its heating coil b4 can still flow automatically to the boiler.

In the embodiment according to Fig. 6 and 7, the additional boiler Dz used directly in the steam and water space of the Langt boiler A. As an introduction opening the manhole is used.

In all of these embodiments, the water must be in the additional boiler must be kept approximately at the same height, so that perfect operation is guaranteed will. For this purpose, a float 1 (Fig. 6 to 8) is provided, which is located in a special housing k is located. If the water in the additional boiler rises above the intended stand, the water in the housing k also rises, lifting the swimmeri and prevents further water from flowing into the boiler.

The equipment required for this is shown in Fig. 8. That Raw water is continuously fed through a pipe 1 by a pump (not shown) The float chamber k is supplied via the check valve m.

If the water in this area rises above the intended level, it rises the float i, and a tooth nl of the float shaft n pushes the valve o to the right, as a result, the water delivered by the pump no longer passes through the check valve m, but flows back directly through the pipe p to the pump.

As can be seen from Fig. 6 and 7, the additional boiler D a shape so simple that it is very easy to clean.

It can also easily be exchanged for a reserve boiler will.

Claims (4)

PATENT CLAIMS: I. Steam locomotive with condensation, characterized in that that with the Lokomotivkessei an additional boiler serving to receive raw water (B or Ü) is connected, except for the amount of steam required for train heating able to deliver a further amount of steam, the condensate of which is used to cover the feedwater losses sufficient. 2. Steam locomotive according to claims, characterized in that the Additional boiler passed through the steam room into the water room of the locomotive boiler is (Figs. 6 and 7). 3. Steam locomotive according to claim i, characterized in that the additional boiler through the steam space of the boiler part containing the furnace to into the fire box (Fig. 2). 4. Steam locomotive according to claim I, characterized in that the Additional boiler free through an opening designed in the manner of a manhole of the boiler shell is inserted into the steam and water space of the locomotive boiler.
