ARRANGEMENT on SYSTEM FOR THE GENERATION or mm.
Application filed October 23, 1926, Serial No. 143,654, and in Germany July 7, 1925.
My invention relates to an arrangement or system for the generation. of steam.
It is already known to generate steam by raising a liquid working medium to its criti- .5 cal pressure, by a pump or other" suitable pressure producing means, and heating it at this critical pressure at least up to its critical ten'iperature. If steam is generated in this manner the working medium passes steadily from the ,liquid into the vaporous state without taking up evaporation. heat. The .advantage of this process resides in the fact that a separation ofsteam and liquid of equal temperatures but of different physical' properties cannot take place at any point of the process. IllthlS way the dam gers are eliminated which are caused in ordinary steam generators by the wellknown ebullition or boiling phenomena.
This process maybe carried out in such a" manner that a plurality of working media with different critical temperatures are con-. verted into steam inseries relation 'The waste heat "of one working medium hereby 2 serves to heat the second working medium, which also stands under critical pressure, up to the critical temperature and thus convert it into steam.
My invention consists in coupling two vapor generating processes insuch manner,
that the'first working medium is atthe critlcal pressure and the critical temperature converted into vapor, while the second working medium takes up the heat at a temperature below its critical value, the pressure of the second working medium being so regulated that it vaporizes at this temperature. The coupling of a steam generating process carried out at the critical values with a 40 steam generating process-carried out below the critical values presents the advantage that no special source of heat is required for the evaporation of the" second working medium and that furthermore a considerabl greater adaptability of thepla'nt is attaine The process of generatingsteam at thecritical values ofthe working medium presumes- 'altion of the plant as otherwise -load 'sturbances cannot" be avoided. Already a comparatively minuate lowering of the pressurebelow t e critical a very sensitive re pressure may cause a considerable wetnessv through "at t of the .ress ure of the live vapor ad manner t of the vapor whereby the risks which this special manner of generating steam is just intended to avoid, arise in a higher degree. In the described coupling of the two steam generation processes it is on the other hand.
possibleto regulate the pressure of the second working medium within wide limits and to bring it also in dependence from the output of the power engine driven by the first working medium, sincethe temperature, at which the first working medium escapes from the po er engine; rises, the falling output of the engine. The second working medimn may hereby lie utilized directly for the storage of energy which is not so easily'possible whenthe steam is generated above the critical values. The entire plant thus becomes more elastic.
In connection with my improved arrangement or s stem an automatic regulation may be provi ed which in dependence from the allowed steam generator controls the furnace of the primary boiler by means known per se.
In the drawing aflixed hereto an embodiment of m invention is diagrammatically illustrated y way of example. In the system or arrangement shown a process for the generation of .vapor at critical values. is coupled with a process for the generation of vapor below the critical values. The first working medium .is drawn up in liquid state by a ,pump l'from the supply tank 2 and is forced at least at the critical pressure as a rule, with limit pressures of the secondary a system of pipes 3 which by means of the burner t is heated at least up to the critical temperature. The vapor produced in this system of pipesis conductedthrough a feed pipe 5 to an engine 6 which drives a dynamo. 7.- 8 is the regulating valve of the engine 6. After the workingmedium has performed passed through work in the en the pipe coil 9 1n which it I is conde'nsdand from whichit flows back tank 2. In order to keep into the'supply the ressure of the working medium at least he critical pressure, a pressure -control device- ;10 is provided which in dependence nets 2. thrott eyalve 11 in the pipe leading om the 1 to the generator 3 in such a at when the pressure falls in the gine6 it is ipe the valve 11 is opened widerand more iiquid working medium supplied while when the pressure in the pipe 5 rises the regulation heated throu h a I pressure in the boiler procedure is reversed.
The secondary vapor generation takes place in a boiler 12 into which t e h uid working medium is fed from a supp y tank 13 by a pump 14. The boiler 12 is pipe coil 9 by which the primary me ium transmits its waste heat to the secondary working medium. Pres- 'sure and temperature of thesecondary vapor generation process is assumed to-be below the critical values of the secondary working medium. The vapor generated in the boiler 12 is led to the consumers through the pipe 15. In the present case, as an example, a turbine 16 and an electric generator 17 are shown as consumers, and the exhaust of the turbine is condensed in a condenser-18 the condensate of which is returned into storage tank 13. The boiler 12 is preferably designed with a large liquid space so that it acts at the same time as storage vessel, reservoir or accumulator. The prime mover 6 may then continuously run under normal load while the prime mover 16 is primarily intended to cover the peak loads. It is capable of doing this inasmuch as the boiler 12.
acting as storage vesselis at all times in a position to supply the volumes of .vapor required for covering the peak loads and the regulation of the rimary vapor generator need therefore rare y come into action.
In the illustration there is, furthermore, shown a re lation of the primary vapor generation in dependence of the secondary vapor generation, which operates in such a manner that a pressure control device 19 adjusts the fuel valve 20 so that when the 12, rises the fuel supply to the heater 3 is reduced and conversely that the fuel supply is. increased when the boiler pressure falls. 4
Various modifications'and changes may be made without departing from the spirit'and the sco e of the invention, and I desire, therefore, at only such limitations shall be pll gced thereon as are imposed by the prior a I claim as my invention 1-- nation .a' supply well, a p pe system constituting a primary vapor generator, a umfi we a for forcing operating liquid from sai into said generator, means for heating the liqluid in said primary generator to a suitab e temperature to generate vapor at critical values, a prime mover connected to said generator, a condenser system connected to the exhaust-side of said prime mover, a secondary vapor generator containing said condenser system as its source of heat supply, means for feeding operating liquid into said seconda generator, a second prime mover connecte to said secondary generator, and means connected with said secondary generator and responding to varying load conditions therein caused by the varying load of the second prime mover, said means being connected with said primary vapor generator to cont-r01 its vapor output in accordance with the. load variations of the secondary prime mover.
2. In a vapor generating plant in combination a supply well, a pipe system constituting a primary vapor generator, a pump for forcing operating liquid from said well into said generator, means for heating the liquidin said primary generator to a suitable temperature to generate vapor at critical values, a prime mover connected to said generator, a condenser system connected to the exhaust side ofsaid prime mover, a secondary vapor generator containing said condenser system as its source of heat supply, means for feeding operating liquid into said secondar generator, a second prime mover connected to said secondary generator, and a pressure responsive means connected with said secondary generator and responding to the pressure variations therein caused by the varying load of the second time mover, said means being connected with said primary vapor generator to control its vapor output in accordance with the load variations of the secondary prime mover.
