In the embodiment according to FIG. 3, the exhaust steam is first through a special preheater o and only then through the connection n to the heating pipes. of what. box 11;
 EMI2.1
 



   This arrangement and design of the preheating device initially has the advantage that by appropriate distribution of the heating surfaces in the preheater o and water tank t the
 EMI2.2
 preheated to about 90 and more, depending on the size of the preheater, before it enters the boiler at r.

Claims

Another advantage of this arrangement is that, for. B., if the feed water in the water tank k is sufficiently preheated, the preheating in the water tank k is completely switched off by setting the three-way tap s accordingly and the steam can be led outside through the tap s, so that the preheating only takes place in the preheater o PATENT -CLAIM:

Device for preheating the feed water in locomotives by means of exhaust steam which is passed through a feed water tank or a pipe system arranged in the preheater, characterized in that in the middle above the blowpipe about the narrowest transverse rubble of the chimney a possibly sharply pointed steam extraction pipe) is arranged that through the same the middle core of the emerging steam jet for the preheating of the water is intercepted.
