Steam Turbine And Boiler

 

What are steam turbines?

Steam turbines are large-scale mechanical devices that are designed to convert the thermal energy from steam into kinetic energy which can then be used to do mechanical work. The mechanical work is focused on a rotating output shaft and this rotary motion is then in turn used to rotate an electrical generator. Though there are other ways to create electricity this is by far the most pervasive technique. It is estimated that about 90% of the United States’ electricity is created using steam turbines. Meanwhile, steam turbines account for about 80% of electricity worldwide.

Steam turbines and boiler

A fuel source is combusted to free the store energy. That energy is then used to heat water into steam. The thermodynamic energy in steam is then used to power a turbine. The turbine is connected to a generator and the generator creates the electricity. Though the boiler itself doesn’t generate the power, boilers are nevertheless a fundamental, indispensable part of the power generation process. So in the power plant, the boiler provides steam, the steam turbine drives the generator to generate electricity.

For electrical power generation the steam turbine will be attached to an electrical generator. The generator needs to rotate at constant synchronous speeds that vary depending on the frequency of the electrical station. The most common speeds are 3,000 RPM for systems that use 50 Hz and 3,600 RPM for systems that use 60 Hz.
