The Effects of Silica on Steam Turbines

Steam turbines are machines that convert the heat energy of steam from a water boiler into rotary motion. Their interior consists of a series of blades that capture the steam and provide a rotational force. As it rotates within a magnetic field, the turbine generates electric power. This principle constitutes 80 ...
