Why is OTEC conducted in a vacuum chamber?

Warm sea water, in an open system, is pumped into a vacuum chamber so that it will boil, and the resultant steam will drive the electricity turbines.


What is the function of gland steam in steam turbines?

Gland steam is steam supplied to the labyrinth glands of the low pressure turbine to prevent air entering in the exhaust side, which disturbs the vacuum (± 50 mbar absolute) in the condenser. Gland steam pressure is to supply at about 0,2 bar.


What are the capacity of Steam Turbines?

The capacity of each steam turbines has more than 530 GW in over 6000 installed units. The steam turbines provide high reliability and sustained high efficiency.


What is the source of power for turbines in electrical power stations?

Turbines are driven by steam so it is thermodynamic energy, but that can be created by burning fossil fuels or by nuclear fission

Fossil fuel plants and nuclear plants both heat water in order to turn?

Steam turbines, which then themselves turn generators.Nearly every method for generating electricity at commercial scales uses turbines at some point (though they may be wind, steam, or water turbines).


Why is excessive moisture in steam undesirable in steam turbines?

moisture present in steam due to quality of steam.


What 2 things do you have today due to the steam engine?

The electric grid (power supply) is one thing mainly dependent on steam engines (turbines), more than 90% of the worlds electric generators use steam turbines to generate electricity (nuclear power plants generate steam to power the turbines). Because of that, anything that uses electricity came into being, such that, we could claim we have computers as a result of the industrial technology created, because of the steam engine.
