A back pressure steam turbine is a type of steam turbine used in power generation systems or industrial processes. It works on the principle of extracting energy from high-pressure steam and converting it into rotational mechanical energy to drive electrical generators or other machines.
In a back-pressure steam turbine, high-pressure steam from a boiler or steam generator is fed into the turbine through an inlet. Steam flows through a series of fixed and rotating blades called stages, causing the turbine rotor to rotate. As the steam expands and passes through each stage, its pressure and temperature decrease, and its energy is converted into rotational motion.
By using the steam at a specific pressure rather than condensing it, a back pressure turbine can achieve higher overall efficiency. It increases energy use by using steam for both power generation and other useful processes, reducing the need for additional fuel consumption.
