Also the bearing journals of rotors are subjected to sliding wear due to rotation at high RPM. Also solids contained in dirty steam cause wear on critical components such as rotor and stator blades, sealing areas and other zones subjected to the steam flow. In the process blade tips of LP turbine rotor get worn out due to droplet erosion thereby reducing the efficiency of rotor.
However, such power plants suffer from severe high-temperature corrosion andĮrosion of critical components mainly triggered by aggressive gases like HCl, H 2S etc., often inĬombination with alkali and metal chlorides that are produced during fuel combustion. Ceramic, CarbideĪnd Cermet based Thermal spray coatings play a significant role in improving the performance ofĬomponents as well as their lifetimes thus significantly increasing the thermal/electrical efficiency ofĪ steam turbine is a device that extracts thermal energy from super-heated high velocity pressurized steam and uses it to do mechanical work on a rotating output shaft.
Raw form of conventional thermal, wind or fluid energy into power include Steam turbine, Gas turbine, Sector has always been under tremendous pressure to provide clean and sustainable energy in the mostĮfficient and cost effective way, acknowledging the fact that the process itself is pretty conventional andĪ technologically advanced system is required to get the desired output. Power Generation sector form the backbone of any country in terms of growth and development.
