    KEY FEATURES OF STEAM ENGINES

    KEY FEATURES OF STEAM ENGINES                         Working Steam engine works with steam made in the boiler. It converts heat energy of steam into mechanical motion. Then it is converted into electrical energy. It is achieved  with the help of a generator coupled with the […]

     STEAM ENGINE PERFORMANCE PARAMETERS OF A STEAM ENGINE Meaning of performance is to study the various efficiencies and losses in a steam engine. we will also like to study how to improve the efficiency. Mechanical efficiency η m e c h = Brake HP/Indicated HP Friction HP = I HP –B HP, energy lost in friction […]

    Losses in steam turbines

    LOSSES IN STEAM TURBINES There are two main types of losses in a steam turbine. (a) Internal losses (Due to flow of steam inside the turbine) (b) External losses (Losses not concerned with steam) The internal losses in steam turbines may be enumerated as follows: Losses due to steam Leakage (i)  Steam leakage in regulating and main valves (ii) Steam […]

    STEAM TURBINES AND STEAM ENGINES

    STEAM TURBINES AND  STEAM ENGINES  STEAM TURBINES Steam turbine is a prime mover which gets its rotary motion from the gradual change in momentum of steam jet by simply changing the direction of the jet which is coming at high velocity from nozzles and striking the blades of the turbine. ADVANTAGES OF STEAM TURBINES OVER […]

    TURBINE THEORY

    Turbine Theory TURBINE It is a device to produce power first by generating rotary motion by consuming kinetic energy of a high speed of the working fluid and simultaneously running the coupled generator. In most of the cases a high velocity jet is produced which strikes the blades, buckets or vanes of the turbine rotating […]
