CONDENSING-TURBINE.
Specification of Letters Patent.
Patented July 25, 1911.
Application filed March 6, 1909. Serial No. 481,816.
To all whom it may concern:
Be it known that I, Gnoncn vES'llNGw HOUSE, a citizen of the United States, and a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have made a new and useful Invention in Condensing-Turbines, of which the following is a specification.
This invention relates to elastic fluid turbines; an object being the production of a compact, efficient, relatively slow speed con- (lensing turbine which is cheap to manufac= tufe and maintain.
In the drawings: Figure-l is a longitudinal section of a turbine embodying this invention; .Fig. 2 is an end elevation and shows such turbine coupled .up to a condensing apparatus; and Fig. 3 is a developed section showing the nozzle and blade lay-out.
The turbine illustrated comprises two reentrant wheels with nozzles and collecting chambers therefor operating in series on steam or other elastic fluid from the same source of supply and the second of the turbines discharges into a condenser. Two running wheels i and 5 mounted on the same shaft 6 journaled in suitable bearings (not shown) are surrounded by a casing 7 provided with steam packing 8 through which the shaft passes.
The casing 7 is divided into halves on its horizontal axis, as is now common, and is provided with a partition or diaphragm 9 which separates the casing into two running wheel compartments. The diaphragm near the hubs of the wheels is provided with steam packing 10 to prevent leakage between the compartments. The lower half of the casing preferably carries all of the nozzlesand collecting chambers for the turbine so that the upper half and the rotor can be removed withoutint'erfering with the, uozzles or collecting chambers. 7
Any number of expansion stages for each of the wheels may be provided and in the drawings, for the sake of illustration merely, I have shownthe series of nozzles 11 for the first or high-pressure wheels and the collecting chambers 12 which coopcoupled to the condensing apparatus l9,
which may be of any type preferred. In
addition to the main inlet 20, the first wheel is supplied with an overload inlet 21 for admitting live steam to the collecting chamber of one of the intermediate stages of expansion.
Leakage from stage to stage and from the stages to the interior of the casing, lying inside of the blades, is prevented by themeans illustrated, the same being described by me in two of my co-pending applications for Letters Patent.
Of course if desired three or more running wheels, may be employed.
In accordance with the provisions of. the patent statutes. I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to ha ve it understood that the apparatus shown is only illustrative and that the invention can be carried out by--other means. i
What I claim is:
1. In a reentrant turbine, a running wheel, a casing divided into a stationary part and a cover, and fluid discharge devices located entirely inthe stationary part.
2. The combination with a plurality. of
reentrant turbine wheels, of a casing for said wheels, divided on its horizontal axis, means divldi'ng said easing into wheel compartments and fluid-discharging devices for 4.
