Any improvement in the design of steam turbine enables more efficient use of fuel and results in reduced cost. The high pressure steam at 5650 C and 156 bar pressure passes through the high pressure turbine. The exhaust steam from this section is returned to the boiler for reheating before being used.
The steam pressure can reach as high as 3500 psig (241.32 bar (g)) at the inlet and as low as 0.5 psia (0.034 bar (a)) at the exit of the steam turbine . Steam turbine…
Consider Installing High-Pressure Boilers with
31/10/2020 · steam temperature of about 640˚C. The High Pressure Boiler generally in a power plant develops steam pressure at 65 bar and steam temperature at 500˚C. Water tube boilers are generally favored for high pressure and high production, however, shell boilers for low
Installation of the steam turbine introduced the need to use water in accordance with the standards PN-EN 12952-10 and PN-EN 12952-12. The water treatment plant is designed and built to supply boiler feed water for high-pressure boilers as well as make-up water for the district heating network.

HP Turbine - High-pressure Steam Turbine | nuclear-power.net
The steam coming out from the turbine is then passed through steam reheater before supplying to low pressure turbine. About 35% of total superheated steam is used for power generation and remaining 65% is used in the evaporating drum for generating steam.
The steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves after giving up most of it. The high-pressure steam from the boiler is expanded in nozzles to create a high-velocity jet of steam. The nozzle acts to convert heat energy in the steam into kinetic energy. This jet is directed into blades mounted on the …
High Pressure Boiler - Coal Fired Boiler, Biomass Boiler Aug 14, 2018· High Pressure Boiler is mostly water tube boiler in which water is on the tube side while flue gas flows through the tube, hence transferring heat from flue gas to water with cross flow heat transfer.
Expansion in the high-pressure stage of the steam turbine A high-pressure stage of steam turbine operates at steady state with inlet conditions of 6 MPa, t = 275.6°C, x = 1 (point C). Steam leaves this stage of turbine at a pressure of 1.15 MPa, 186°C and x = 0.87 (point D).
Turbine with steam extraction: It is carried out in high-pressure stages, sending part of the steam back to the boiler to overheat it and re-send it to intermediate stages. In some occasions, the steam can also be extracted from some stage to derive it to other industrial processes.
High pressure boilers (1) - SlideShare 2/2/2016 · Thus, a boiler operation at high pressure will require less heat addition for steam generation. 3.1 Features of High pressure Boilers High-pressure boilers have the following features: Forced circulation of water – in all
