Back Pressure Steam Turbine

What is a Back Pressure Steam Turbine and what is its

The high pressure, high temperature steam turns a turbine; having done the useful work, the steam leaves the turbine at a lower temperature and pressure. This steam is condensed into water, which again enters the boiler and the cycle repeats. The above structure works quite good for a system whose main aim is to generate power. Now, consider a

Types of Steam Turbine - an overview | ScienceDirect

The back pressure steam turbine is so-called because the steam exiting the turbine exhaust will still contain a significant amount of energy and will be at relatively high temperature and pressure. This exhaust steam is used either to provide heat for an industrial process or to produce hot water.

What are the effect if high back pressure in steam

High backpressure causes the steam exiting the turbine to have higher enthalpy than it would at a lower backpressure, and this higher exit enthalpy causes a decrease in both power output and turbine efficiency. High backpressure also causes the ex

Effect of exhaust pressure | The steam turbine

2018-6-2 · The efficiency of the cycle is strongly influenced by the LP turbine exhaust pressure. The back pressure of the condenser sets the saturation temperature at which the expanded steam rejects its latent heat of vaporisation to the cooling water. Consequently, changes in back pressure affect the temperature of cycle heat rejection.

The steam turbine operates on basic principles of thermodynamics using the part of the Rankine cycle. Superheated vapor (or dry saturated vapor, depending on application) enters the back pressure turbines, after it having exited the boiler, at high temperature and high pressure. The high heat/pressure steam is converted into kinetic energy
