In Section 1, steam turbine operating conditions are described including the steam cycle, the chemical control of the steam/water circuit and the distribution of temperature, pressure and steam wetness in the turbine.
Steam turbines work on the principle of the Rankine cycle, which consists of a heat source (boiler) that converts water into high-pressure steam. A multistage turbine allows the high-pressure steam to expand, which lowers its pressure. The steam is then transported to a condenser, which is like a vacuum chamber and thus has negative pressure and converts, or condenses, the steam into water
principle is made use in hydraulic turbine. In a turbine, blades or buckets are provided on a wheel and directed against water to alter the momentum of water. As the momentum is changed with the water passing through the wheel, the resulting force turns the shaft of the wheel performing work and generating power. A hydraulic turbine uses potential energy and kinetic energy of water and
