Basic Concept of Gas Turbines for Power Generation
The gas turbine used for power generation is a type of rotary heat engine that is activated by high pressure, high temperature gas to produce mechanical energy, which is then converted into electrical energy by the generator connected to the turbine. Liquefied natural gas (LNG) emits comparatively less fine particulate matter(PM 2.5), about one-ninth of that emitted by the burning of coal, and the emission level of atmospheric pollutants, such as sulfur oxides and nitrogen oxides, is also about just one-third of that emitted by coal, revealing just how environment-friendly LNG is as a fuel.
