What are the 2 main types of wind turbines?

What are the 2 main types of wind turbines?

There are two basic types of wind turbines:

  • Horizontal-axis turbines.
  • Vertical-axis turbines.

What are water turbines used for?

A water turbine is much like a windmill, except the energy is provided by falling water instead of wind. The turbine converts the kinetic energy of falling water into mechanical energy. Generator. Connected to the turbine by shafts and possibly gears so when the turbine spins it causes the generator to spin also.

What is the difference between a steam turbine and a gas turbine?

Steam turbines deliver power at a smooth, constant rate, and the thermal efficiency of a steam turbine is higher than that of a reciprocating engine but lower than gas turbine engines due to higher operating temperatures of the gas turbines (Gas turbines ~1500°C and steam turbines ~550°C).

How do gas turbines work?

Gas turbines, steam turbines, and water turbines are all turbines, meaning they are devices which continuously convert energy stored in a fluid into work. The turbine rotates as the working fluid is constantly flowing through it, and if you connect something to the shaft it can do work.

What is the efficiency of a gas turbine?

Gas turbine efficiencies range between 29 and 33\%. Gas engine efficiencies range between 48.5\% and 49\%. Energy Ratio of Cogeneration In a gas turbine, the energy ratio of cogeneration consists of electricity (33 percent), steam (50 percent), and loss (20 percent).

What is the internal temperature of a gas turbine?

In the gas turbine, the internal temperature reaches 1,500 degrees Celsius, which is significantly hotter than a steam turbine’s temperature. In the steam turbine, the internal temperature only reaches 500 to 650 degrees Celsius, less than half of the temperature of gas turbine reactions.
