![]() ![]() Super-heated steam then flows through the turbine. The steam generated is passed through the superheater. Heat produced due to burning of coal is utilized in converting water contained in boiler drum into steam at suitable pressure and temperature. Coal received in coal storage yard of power station is transferred in the furnace by coal handling unit. ![]() Miller, Computational Methods of Neutron Transport, American Nuclear Society, 1993, ISBN: 2-4.Figure shows a schematic arrangement of equipment of a steam power station.

Less responsive to changes in power demand compared with gas turbines and with reciprocating engines.They have longer startup than gas turbines and surely than reciprocating engines.Steam turbines are less efficient than reciprocating engines at part load operation.Steam turbines have greater reliability, particularly in applications where sustained high power output is required.Īlthough approximately 90% of all electricity generation in the world uses steam turbines, they also have some disadvantages.In general, the turbine moves in one direction only, with far less vibration than a reciprocating engine.This implies lower mass flow rates compared to gas turbines. In general, steam contains a high amount of enthalpy (especially in the form of heat of vaporization).They are made in various sizes up to 1.5 GW (2,000,000 hp) turbines used to generate electricity. Steam turbines are suitable for large thermal power plants.Fewer moving parts than reciprocating engines.The very high power-to-weight ratio, compared to reciprocating engines.The thermal efficiency of a steam turbine is usually higher than that of a reciprocating engine.Since the steam turbine is a rotary heat engine, it is particularly suited to be used to drive an electrical generator.The reheater heats the steam (point D), and then the steam is directed to the low-pressure stage of the steam turbine, where it expands (point E to F). High content of water droplets can cause rapid impingement and erosion of the blades, which occurs when condensed water is blasted onto the blades. The steam must be reheated to avoid damages that could be caused to the steam turbine blades by low-quality steam. Steam Turbine Diagram with Parts generator#In HP turbine, the high-pressure stage receives steam (this steam is nearly saturated steam – x = 0.995 – point C at the figure 6 MPa 275.6☌) from a steam generator and exhaust it to moisture separator-reheater (MSR – point D – ~ 1.15 MPa ~186☌ x ≈ 0.9).
