What is Boiler and Condenser Pressure - Rankine Cycle - Definition

22/5/2019 · Decreasing the turbine exhaust pressure significantly increases the specific volume of exhausted steam, which requires huge blades in last rows of low-pressure stage of the steam turbine. In a typical wet steam turbines, the exhausted steam condenses in the condenser and it is at a pressure well below atmospheric (absolute pressure of 0.008 MPa, which corresponds to 41.5°C).

Source: Babcock & Wilcox. Total heat rates for condensing steam turbines, including boiler efficiency losses, typically range from 7,500 to 15,000 Btu/hp-h (10,612 to 21,222 kJ/kWh). This correlates to thermal efficiencies ranging from 34 to 17% (HHV). Other than the 15 to 20% boiler efficiency losses and various minor losses in the turbine

Relation Between Steam Turbine Inlet pressure and Steam …

In a backpressure steam turbine, energy from high-pressure inlet steam is efficiently converted into electricity and low-pressure exhaust steam is provided to a plant process. The turbine exhaust steam has a lower temperature than the superheated steam created when pressure is reduced through a PRV. In order to make up for this heat or enthalpy loss and meet process energy requirements, steam plants with backpressure turbine installations must increase their boiler steam …
