höyryturbiinijärjestelmät

Höyryturbiini is the Finnish word for steam turbine. A steam turbine is a rotary engine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. The steam is generated in a boiler, where water is heated to produce high-pressure steam. This steam then flows through a series of turbine blades, causing them to rotate. The rotation of the blades drives a generator, which produces electricity.

Steam turbines are widely used in power generation, particularly in thermal power plants. These plants can be fueled by various sources, including coal, natural gas, nuclear energy, and biomass. In nuclear power plants, the heat generated from nuclear fission is used to produce steam, which then drives the turbines. Similarly, in fossil fuel power plants, the combustion of coal or gas heats water to create steam.

The design of steam turbines varies depending on their application. They can be single-stage or multi-stage, with different types of blades and casings to optimize efficiency and power output. The steam can be expanded in a single turbine or in a series of turbines, each operating at a different pressure and temperature.

In addition to power generation, steam turbines are also used in industrial applications, such as in refineries and chemical plants, where they can be used to drive pumps, compressors, and other machinery. The efficiency of a steam turbine is a critical factor in the overall performance of a power plant or industrial facility, and considerable research and development efforts are focused on improving turbine design and operation.
