In a steam turbine, steam at 20 Bar and 500 degrees

Transcribed image text: In a steam turbine, steam at 20 Bar and 500 degrees Celsius is expanded to 10 Bar where 20% of steam is bled off to an open feedwater heater. And the remaining steam continues to expand until it becomes saturated. The steam is then reheated to the same boiler temperature and expanded and bled off steam to another feedwater heater at a pressure of 1 Bar.

Jun 17, 2021 · Combined heat and power (CHP) | The steam turbine. The function of the cooling water in the condenser is to extract the latent heat of evaporation from the steam exhausted by the turbine and this is done at the saturation temperature corresponding to the pressure i.e. at 33-45°C to 49.5°C for pressures of 50-120 mbar.

May 14, 2012 · In a 100-MW steam turbine at a pressure of about 600 psia (41.4 Bar) and 660 °F (350 °C), a 1% reduction in steam consumption can cost between $500 000/year and about $900 000/year. This is based on a boiler efficiency of about 85% and lower heating value (LHV) of fuel at 18 900 Btu/lb (10 500 Kcal/kg).

BR Mini Steam Turbines - specification

For example, if the company has a boiler that can operate with 7 kg / cm2 (or 7 bar) corresponding to steam at a temperature of 170 celsius degrees and the production process of the company needs steam at 170 degrees, there is nothing left to the turbine, because the steam must leave the turbine at 7 bar. If, for exemplo, the steam enters the

Steam enters the high-pressure turbine at 120 bar and 520 o C and expands to 10 bar, where some of the steam is extracted and diverted to a closed feedwater heater. Condensate leaves the feedwater heater as a saturated liquid at 10 bar and then passes through an expansion valve before it is combined with the effluent from the low-pressure turbine.

A back pressure steam cycle works as follows. The boiler produces 8 kg/s of steam at 40 bar and 500oC. This is expanded to 2 bar with an isentropic efficiency of 0.88. The pump is supplied with feed water at 0.5 bar and 30oC and delivers it to the boiler at 31oC and 40 bar. Calculate the net power output of the cycle. (Answer 5.24 MW)
