Turbine wheels and power plants
Abstract
"A turbine water-wheel is one through which the water passes guided by channels either interior or exterior to the wheel its self and the walls of these channels or guides as they are termed, are placed in such positions, as to impinge the water on to the blades or wheel buckets at such an angle as will insure the greatest efficiency. The guides and buckets are usually curved in opposite directions, and are so placed with regard to each other, that the water enters the wheel with the least possible shock and leaves it with the least possible velocity. Turbines may be placed in any position from a horizontal to a perpendicular and another advantage they possess over the old style of wheel is, the higher the fall, the smaller the wheel required, whereas with the overshot wheel (the best form of old style) the reverse is the case. The velocity of a small turbine under a high fall is necessarily very great and this proves to be an advantage too, for it permits of the doing away with the heavy and expensive gearing which was necessarily used in connection with the old style wheels of great power; and it also gives a greater regularity of motion. The turbine was first introduced into general use by Fourneyron in France, in 1827 and shortly after, it was used in England, and later it was introduced into the United States, by Boyden. Turbines are termed inward- flow, outward-flow and parallel-flow wheels, &etc. according to the direction the water takes in passing through them. The modulus of a wheel is found as follows: The amount of water flowing through the wheel is found by gauging and its weight is measured by the height of fall; The actual amount of power exerted by the wheel is ascertained by means of a dynamometer"--pages 3-4.
