Steam Turbine Configuration

چکیده
Most electric power is produced by steam turbines. This is because the steam cycle is well suited to the conversion of heat to work and steam turbines can be built in a wide range of capacities up to about 1500 MW. Steam turbines are basically very simple having fixed blades to accelerate the steam and moving blades to absorb the resulting kinetic energy. The moving blades are mounted on a rotating shaft which drives an electrical generator. A characteristic of the steam turbine is the ability to produce high power outputs in a fairly compact machine though steam turbines are by no means small.

Silicone-polyether Copolymers as New Steam Turbine Oil Demulsifiers
Turbine oil plays an important role in supporting optimal steam turbine performance. Some additives in turbine oil can cause emulsification when the oil is contaminated by water, so demulsibility is a very important property of the steam turbine oil. In order to improve the demulsibility of steam turbine oil, two kinds of polyether-silicone comb copolymers are synthesized and used as steam turb...

متن کاملTechno-Economic Assessment of Different Inlet Air Cooling Systems in Warm Dry & Wet Climate Stations
Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...
