ELECTRICAL ENCYCLOPEDIA

What is a Natural Gas?   Natural gas is a gas consisting primarily of methane, typically with 0–20% higher hydrocarbons[1] (primarily ethane). It is found associated with other hydrocarbon fuel, in coal beds, as methane clathrates, and is an important fuel source and a major feedstock for fertilizers. Most natural gas is created by two mechanisms: biogenic and thermogenic. Biogenic gas is created by methanogenic organisms in marshes, bogs, landfills, and shallow sediments. Deeper in the earth, at greater temperature and pressure, thermogenic gas is created from buried organic material. continue.. Electricity from Natural Gas   The stock of natural gas, like other fossil-based fuels, is limited and is therefore not a renewable resource. The combustion of natural gas produces only a fraction of the nitrogen oxide and carbon dioxide emissions of oil and coal, and also results in essentially no particulate matter or sulfur dioxide emissions. Natural gas therefore becomes an attractive

What is a Coal?   Coal is a combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, with smaller quantities of sulfur, oxygen and nitrogen.. continue..   What is a Coal fired power station?   A coal-fired power station produces electricity, usually for public consumption, by burning coal to boil water, producing steam which drives a steam turbine which turns an electrical generator. Power station operators play a key part in keeping the boilers fired equally and steam adjusted correctly to burn the coal in the most efficient way possible.. continue..

What is the difference between fission and fusion?   Let’s put it in the simplest terms: Fusion works by smashing atomic nuclei together to create heavier nuclei. In order to make this happen, you have to heat things up a bit—say, a few million degrees Celsius. Fusion is promising as an energy source (and potentially dangerous) because it’s exothermic—it produces more energy than it requires to start it and is therefore self-sustaining. How much energy can fusion produce? Well, our sun’s been working for several billion years just fine on fusion... continue.. Fusion Power   Fusion power is power generated by nuclear fusion processes. In fusion reactions two light atomic nuclei fuse together to form a heavier nucleus (in contrast with fission power). In doing so they release a comparatively large amount of energy arising from the binding energy due to the strong nuclear force which is manifested as an increase in temperature of the reactants. Fusion power is a primary area of researc
