Lämpövoimatuotanto

Lämpövoimatuotanto refers to the generation of electricity from heat. This process typically involves heating a fluid, such as water, to produce steam. The high-pressure steam then drives a turbine, which is connected to a generator that produces electricity. The primary sources of heat for thermal power generation vary widely and include fossil fuels like coal, natural gas, and oil, as well as nuclear reactions and renewable energy sources such as biomass and geothermal heat.

In fossil fuel-based thermal power plants, the combustion of fuels releases heat that boils water into steam. Nuclear power plants utilize the heat generated from nuclear fission to produce steam. Geothermal power plants tap into the Earth's internal heat, while biomass power plants burn organic materials. The efficiency of thermal power plants is influenced by factors such as the operating temperature and pressure of the steam, as well as the technology used. Waste heat recovery systems are often implemented to improve overall energy efficiency by capturing and utilizing heat that would otherwise be lost. Thermal power generation remains a significant contributor to the global electricity supply, although the environmental impact of different heat sources, particularly fossil fuels, is a major consideration in energy policy and technological development.
