What are steam turbines used for in the power industry?

Steam turbines convert thermal energy from pressurised steam into mechanical energy to generate electricity. They are integral to thermal power plants, including coal, gas, and nuclear power stations, as well as renewable energy facilities such as biomass and concentrated solar power plants. The mechanical energy produced is used to rotate generators, producing electrical power.

How do steam turbines contribute to cleaner energy production?

Modern steam turbines, integrated with technologies like Integrated Gasification Combined Cycle (IGCC) and carbon capture systems, reduce emissions and improve energy efficiency. These advancements help meet stringent environmental regulations, making thermal power generation more sustainable and acceptable.

What are the main types of steam turbines used in power generation?

There are three primary types of steam turbines: condensing, non-condensing, and extraction turbines. Condensing turbines are the most common in large-scale power plants, converting maximum energy into electricity by condensing exhaust steam. Non-condensing turbines are used in industrial applications, while extraction turbines allow for more flexible power generation.

Which companies lead the steam turbine manufacturing industry?

Global leaders in steam turbine manufacturing include companies such as GE Power, Siemens, Mitsubishi Power, and Doosan Enerbility. These companies develop advanced turbine technologies for various applications, offering solutions that enhance efficiency and reduce emissions in power generation.

How has steam turbine technology evolved in recent years?

Steam turbine technology has evolved with the development of supercritical and ultra-supercritical turbines, which operate at higher temperatures and pressures for greater efficiency. Carbon capture and storage (CCS) integration has also become more prevalent, helping to reduce the environmental impact of thermal power generation.
