Reciprocating Engine or Steam Turbines. Thesteam next goes from the separator to the main power generating units. The main units in earlier practicewere reciprocating engines, in modern installationsthey are steam turbines. Reciprocating engines may be divided into severalclasses, the details of which will not be outlined inthis general discussion. Suffice it to say, however,that the main principle upon which reciprocating en-gines act is that steam enters a cylinder under pres-sure, thus forcing ahead a piston which is connectedto a crank arm, thereby causing rotation and the con-sequent generation of power. Steam turbines are divided into two general classesknown as impulse turbines and pressure turbines. Inthe impulse turbine steam is allowed to expand inpassing through a nozzle, thus causing the steam totravel at an enormous velocity. The steam, having. Vertical Type Steam Turbine With Condenser Base. acquired this velocity by impinging against movableblades, causes rotation and the consequent generationof power. In the pressure turbine, however, the steamis allowed to enter the buckets or rotating vanes at acomparatively low pressure. These vanes are so de-signed that the steam may expand in this movableportion and by means of its expanding pressure causerotation and hence the generation of power. Turbines as a general rule have two other classi-fications known as vertical and horizontal. The ver-tical turbine revolves upon a vertical shaft, which issupported at the bottom by a thin film of oil under 202 JOURNAL OF ELECTRICITY, POWER AND GAS [Vol. XXXII—No. 10 the high pressure of about 900 to 1000 lb. per in. Thehorizontal turbine, however, as the name indicates,rotates on a horizontal axis, and is supported in theusual manner, by means of suitable bearings. Condenser. From the steam turbi
