THE SPIRO STEAM TURBINE
Fig. 4 shows a turbine of 10 horsepower capacity that is directly connected to a 25-inch fan which, at present, is furnishing forced draft through Jones underfeed stokers for a 300 horsepower boiler. These turbines are said to be highly adapted to fan service as the high rotative speeds enable the size of the outfit to be reduced to a minimum. When the turbines are coupled to fans having a constant load, no governor is used, but for variable loads, a sensitive quick-acting governor is provided. These turbines are also applicable to the driving of centrifugal (pumps, for auxiliary service on shipboard where economy of space is so important, and for many other obvious purposes. The starting torque is high and the maximum speed quickly obtained.
Tests made on turbines of this type show the following results: (1) Capacity of turbine, 25.3 horsepower; boiler pressure, 120 pounds; initial pressure, 101.5 pounds; speed, 2450 revolutions per minute; water per brake horsepower, 53.2 pounds (non-condensing).
