It is a mechanical device that extracts heat energy from vapor pressure, and converts it into rotating motion. Its modern look was invented by Sir Charles Parsons in 1884 It almost replaced the piston steam engine.

This is primarily due to the increase in its thermal efficiency and the increase in the energy generated from it in relation to weight Because turbines generate rotating motion, they are particularly well suited to be used to rotate generators that produce electricity at a large scale in power stations about 80% of the world's electricity is generated by the use of steam turbines. This applies to power plants that run on coal oil or nuclear reactors, as they all convert the heat of the fuel into high pressure steam, and by means of a steam turbine the steam turbine is operated and with it the electric generator rotates producing electrical energy that operates factories and supplies electricity to homes. Solar power plants are also based on heating water heating oil, or heating salts.

They heat the water with the heat of the sun and turn it into steam, and from the steam the electric current is produced by a turbine and an electric generatorThese are excerpts from steam turbines In the course we are working on explaining 5 basic topics which are 1- Ideal Rankine Cycle and main components of steam power plant 2-Steam generator characteristics, heat transfer modesand operation3-Turbine sector and turbine operation4-Overhaul and maintenance 5-Control and InstrumentationsWe will explain 5 topics and divide each lecture into parts and explain it in detail so that the viewer knows what the steam turbines are accurately described This course is for both the beginner and the professional. If you are looking for work or self-development or know maintenance, operation and repair Steam turbines The course is divided into 24 videos, number of hours 11Includes explanation and information from start to professionalism And that's a description of lectures to explain. 1-ntroduction to Steam Power Plants2-Rankine Cycle Modification on Rankine Cycle How to increase efficiency of Rankine Cycle Power plants main components How Generator worksHow turbine works3-Steam Generator System Design considerations Ash CharacteristicsWater CirculationNatural Circulation Forced CirculationDrumSuperheaters and ReheatersEconomizerDraft SystemFansAir HeatersGaseous EmissionSteam Generator Control Firing System Boiler Operation4-Steam turbines Configuration and components Part load operation Steam turbine theory Impulse principleReaction principle Radial flowAxial flowTurbine classification Turbine cylinder Double shell casingDisk rotorWelded rotorTurbine bladesImpulse type bladingReaction type bladingVelocity diagram Velocity compounded stageDegree of reaction Blade fixing in rotorTurbine Operation5- Steam turbine accessories Turbine bearings Journal bearing Thrust bearing Lubrication systemCouplingFlexible couplingSolid couplingShaft gland sealTurbine seal ringsGland exhaust system Turbine gearTurbine control valvesSteam turbine operationIntroduction Preparing turbine auxiliary Turbine lubricants StartingWarming up turbine Thermal stressTurbine vibration Turbine shut down Annual maintenance Thrust bearing inspection Preventive maintenanceDescription of lectures 1- Introduction to Steam Power Plants and overview of the system2.
