Patented June 11,1907.
' Application filed December 22,1906. Serial No. 292,902-
To all whom, it may concern: Be it known that I, FREDERICK SAMUEL- SON, a subject-of the King of Sweden, residing at Rugby, En land,'have invented certain new and usefdl Improvements in -.Elastic- Fluid Turbines, of which the following is a specification.
This invention relates to steam turbines and has for its object to provide simple and efficient means for separating moisture from the steam in its passagethrough a turbine of the multi-stage type, thereby preventing the loss inefficiency arising from the presence of moisture in the steam during its passage through the turbine.
. The accompanying drawing which is a art.
sectional view of a multi-stage turbine o the Curtis type, clearly illustrates one method of carrymgm inventioninto eifect.
In the a'wing 1 re resents the turbine casing, 2 the shaft ant 3 the rotating elemerits or ,wheelscarrying the fluid receiving vanes or buckets 4 on their peripheries. Each of the wheels 8-,is shown as provided with three rows of buckets and inter osed between these rows. are-stationary buc ets 5 secured to the cas' 1. y
Iihe' turbine illustrated is a two-stage machine and the steam. is delivered into each of the stages througlinezzles 6, which may be e anding or non-expanding in characters he nozzles of the second stage are secured on the underside of a dis hragm iseparating centrifugal force .and collects in an annular the first from the seconc stage. On the upper side of diaphragm 7 is secured an inclined annularpartition S which overhangs the dis-j tributing nozzles 6 of the second stage and extends -for some distance toward the axis of the turbine, so that the steam as it is discharged from the first wheel is caused to flow radially inward toward the turbine shaft and thenl'outward under the partitions 8 to the pozzles of the second stage. Any moisture in the steam instead;of gassing radially inward with'the steam is t own outward by de'ression-ior channel 9 formed at the' perip hery of" the diaphragm 7. By thus de fleeting the steam in its passage between sta es themoisture is effectively separated and the: steam is delivered to. thesucceedingeta sin a dry condition.
be water which collects in the channel 9 may be discharged from'the turbine but I my invention a plura 'employed to direct thesteam' in any prefer to provide drainage-channels 10 some or all of which may be fitted with stop-cocks 11. These channels discharge the water into an annular chamber 12 the water passes through passages 13 on to the diaphragm of the second stage. Some of the water which isthus drained off from the first to the second stage is caused to evaporate owing. to the lower pressure and the steam so roduced does useful work in passing througi the remaining stages of the turbine.
Steam or other elastic fluid is admitted by the chest 14 containing one ormore admission valves. C In the resentillustration of iity of valves are employed, each under the control of an electromagnet 15. J
Mounted in the base of the turbine is a condenser 16. and between the condenser tubes and the last wheel is awall or dia- 'hragm l7 slanting toward the shaft and oYming a part of the condenser casing.- It is provided with suitable openings, shown in dotted lines, to enable the steam-topass to the condenser tubes. This wall may also be desired manner through the condenser.
. Although I have particularly described my invention as applied to a two-stage tu-r- "bine of the Curtis type it will be obvious that it is equally applicable to turbines havin more than two stages and also to any vertica discharging devices, wheel buckets acted upon by the fluid from said devices, and an annular device which causes the fluid exhausting from one stage to flow inwardly toward the shaft to discharge moisture in so doing, and to flow outwardly to the fluid-- 'dis'chargin devices of a lower-pressure stage. 2. e astic-i luid turbine of the mutistage type: having means for preventing moisture from passing with the fluid from one stage to the next comprising an annular inclined partition overhanging the inlet nozzles of a stage so that the fluid has to pass inward toward the axis of the turbine and then outward to the nozzles, the liquid being thrown outward While the elastic fluid is passing inward, substantially as described.
3. In'an elastic-fluid turbine of the multistage type, the combination of inlet nozzles, an inclined annular plate overhanging the inlet nozzles between one stage and the next succeeding stage, an annular channel surrounding said plate, and passages leading from said annular channel to the succeeding stage, substantially as and for the purposes described. a
4. In an elastic-fluid turbine which is divided. into stages of expansion, fluiddischarging devices and wheel buckets for each stage, and a means for separating moisture from the fluid as it flows from one sta e'tb another, comprising a plate for suddenly changing the direction of flow, one or more passages receiving the liquid discharged "from the fluid and that flowing over the plate, and a means in a stage of lower pressure for collecting the liquidand dischar ing it at a point or points out of the norma path of the entering fluid.
In witness whereof, I have hereunto set my hand this 7th clay ofDeeember, 1905.
