Specification of letters Patent.
Patented June 20, 1022.
Application filed February 21, 1921. Serial No. 446,868.
To all whom it may concern.
Be it known that I, NrLs' GUs'rAF Hnzn- KIEL FRENNE, subject of the King of Sweden, residing at Fleminggatan -13, Stockholm, Sweden, have invented certain new and useful Improvements in Locomotive Sheds or the like, of which the following is a specification.
According to the methods heretofore practised in locomotive sheds and other gathering places for locomotives, an engine, when coming in only to be again put on service after a few hours, has been heated all the time when in shed, and the pressure of the steam has been maintained immedi ately below the operating steam pressure of the engine. Locomotives not wanted in service for a longer time have been allowed to cool down until the pressure has sunk to zero, after which the water has been emptied from them.
This'way of managing the service will be found to be highly uneconomical. In the first instance large quantities of fuel are consumed by nursing a small fire in order to compensate for the losses of radiation, the fuel combustion being then very incomplete, while the furnace is operated approximately as a gas generator. Secondly, the losses due to radiation will be rather great when the pressure or the temperature of the locomotive is kept high; as is well known, the losses due to radiation are proportional to the difference between the temperature of the water in the boiler and the temperature of the surrounding atmosphere. In locomotives which are not to be used anew, and which are thus allowed to cool down, the whole quantity of heat contained in the boiler of the locomotive will be wasted.
The present invention has for its ob ject, partly to utilize a large quantity of the heat contained in a locomotive boiler which is to be put out of service, and partly to keep a locomotive boiler ready for service in an economical manner. The invention comprises a steam storer provided with means for connecting a locomotive boiler thereto, steam or water being supplied to the said storer from the locomotive boiler, or vice versa. By this arrangement the heat of the locomotive, or part thereof, may be stored in the storer with only small losses of heat; the said stored heat can then on demand be reintroduced into a locomotive boiler or any other appliance.
The invention is illustrated in the accompanying drawing in which the figure is a diagrammatic View of a locomotive shed.
Referring to the drawing in detail A indicates the storer to which steam is supplied through the steam piping S and water through the water piping V from a locomotive T or vice versa, the locomotive running on the lines L.
Thus, after a locomotive T has been brought into the shed to be put out of service, or to be left standing for a longer time, the heat thereof, or part of such heat, is supplied to the storer A in which it is stored. In order to utilize as much as possible of the heat, the storer is adapted for very low pressures. The steam space of the locomotive boiler is connected with the storer by the pipe S and, while the pressure is allowed to sink in the locomotive boiler, the steam is supplied to the steam storer or, if desired, the water space of the boiler may be connected with the storer by the pipe I so that the hot water is brought into the storer. If this locomotive or another one is then to be used again without change of water, steam or water is supplied to the locomotive boiler from the storer either during the whole of the time until the locomotive shall be used, or, only during the latter part of the time, before using it. Immediately preceding the using of the locomotive, the same is heated up in the usual manner, and the water in the locomotive boiler having been kept at a temperature of for instance 100 to 110 centigrade, there is required but a relatively short time and little fuel only for raising the temperature of the locomotive for instance to 180", or corresponding to the pressure used in service. The combustion then being much more thorough, owing to the load on the grate surface approaching the normal one, the fuel will be utilized in an entirely economical manner.
Of course, the steam storer may also receive steam from sources other than the locomotive boilers, for example from a stationary steam boiler plant or the like.
What I claim as new and desire to secure by Letters Patent of the United States is An arrangement in locomotive sheds or other similar places where locomotives are brought in either for changing water or in order to stand ready for service during a longer or shorter period, consisting in a steam and Water storer provided with connecting means by which a locomotive boiler may be connected thereto to permit steam or Water to enter the said storer from the locomotive boiler, or, vice versa, to permit steam or Water to enter a locomotive boiler from the said storer, so that the heat of the locomotive, or part thereof, in the form of steam or heated Water, may be stored with only small losses of heat, in order to make it possible to supply this heat back 15 again to the boiler ot' the locomotive, when rmnired.
In testimony whereof I affix my signature in presence of two Witnesses.
