Natural gas power plant

Natural gas power plant

Natural gas power plants generate electricity by burning natural gas as their fuel. There are many types of natural gas power plants which all generate electricity,but serve different purposes.All natural gas plants use a gas turbine , natural gas is added,along with a stream of air,which combusts and expands through this turbine causing a generator to spin a magnet, making electricity. there is waste heat that comes from this process, because of the second law of thermodynamics.Some natural gas plants use this waste heat as well, wich is explained below

Natural gas power plants are cheap and quick to build.They also have very high thermodynamic efficiencies compared to other power plants.Burning of natural gas produces fewer pollutants like NOx, SOx and particulate matter than coal and oil . on the other hand , natural gas plants have significantly higher emissions than a nuclear power plant.This means that air quality tends to improve when switching to natural gas plants from coal plants_but nuclear power does even ,more to improve air quality

Despite the improved air quality,natural gas plants significantly contribute to climate change , and that contribution is growing (see pollutant vs greenhouse gas).Natural gas power plants produce considerable carbon dioxide,although less than coal plants do.on the other hand, the process of getting nutural gas from where its mined to the power plants leads to considerable release of methane(natural gas that leaks into the atmosphere.) As long as natural gas plants are used to produce electricity their emissions will continue to warm the planet in dangerous ways
