Nuclear power stationNuclear power station

►Nuclear power station– the object of industry and energy (heat and power plant), producing electricity by using energy from fission of nuclei of atoms, mostly of uranium (natural uranium or slightly enriched in the isotope U-235), in which heat is necessary to obtain the pair, is obtained from nuclear reactor.

Construction of nuclear Construction of nuclear power stationpower station

► The general principle of a nuclear power plant (for example, circulation PWR):

► In a nuclear reactor by the reaction of fission of atomic nuclei emit large amounts of heat that is picked up by a working medium (usually water under high pressure in the so-called primary circuit - PWR and WWER reactors). Factor flows to the steam generator, which supplies heat to the boiling water re-circulation of a lower pressure, and then returns to reactor. Water vapor (steam wet, which is dried before reaching the turbine - the water molecules in a pair of wet, high pressure turbine have destroyed, so first couple passes wet from the steam generator systems drying before it reaches the turbine) then drives the steam turbine combined generator. Separation of circuits is more secure in case of leakage from the steam turbine.

Friendly: renewable energy sourcesLess friendly: coal combustion petroleum nuclear energy (already mentioned) burning of fossil fuels

Renewable energy sources are energy sources, whose use is not associated with their long-term deficit - the resource renews in a short time.

The most important renewable energy is a drop of water. Other renewable sources include:

solar power (mentioned earlier), wind energy (already mentioned) biomass, biogas, geothermal energy , hydropower.

Renewable energy should not be confused with energy environmentally friendly because its production facilities may (but need not) cause environmental damage.

Biomass - mass of matter contained in the organisms. Biomass is given in relation to the surface (per square meter or kilometer) or volume (eg in the aquatic environment - per cubic meter).

Biomass is expressed in terms of fresh weight (living organisms or natural mass of living organisms) and dry mass (weight of living organisms after drying or evaporation of water). Biomass is expressed in units of weight (eg gram or kilogram) and also in terms of organic carbon, or in units of energy (calorie, joule).

        Measurement of biomass can calculate the biological production (see productivity) of the individual units of biological organization: individual, population, biocenosis ecosystem, biom

or the entire biosphere.

Through photosynthesis solar energy is accumulated in the biomass, plant organisms initially, and later in the food chain and animal. Energy contained in the biomass can be used for human purposes. This involves the processing of other forms of energy by biomass burning or incineration of its degradation products. As a result of heat of combustion is obtained, which can be processed into other forms of energy such as electricity.For the purposes of energy is used most often :

timber of low technological quality and waste animal faeces sludge straw, oil cake and other wastes of agricultural

production seaweed grown specifically for energy purposes organic waste such as beet pulp, corn stalks, grass,

alfalfa vegetable oils and animal fats.

Biomass energy is achieved inter alia through :

gasification - producer gas (mainly hydrogen and carbon monoxide) resulting from gasification of biomass in closed reactors (so-called gazogeneratorach) - it is burned in a boiler or directly drives a gas turbine or internal combustion engine can also be a raw material for Fischer-Tropsch synthesis.

by fermentation of biomass derived biogas, methanol, ethanol, butanol and other compounds that can be used as fuel.

esterification – biodiesel.

Biogas, landfill gas - a combustible gas, the product of anaerobic fermentation of organic compounds (eg sewage, including waste water, sugar, municipal waste, manure, slurry, waste, agri-food industry, biomass) and partly also to their decay resulting in a biogas plant . As a result of combustion of biogas formed contrary beliefs as much nitrogen oxides, which in case of combustion of fossil fuels.

The crude biogas consists of approximately 65% (between 50-75%) of methane and 35% of carbon dioxide and other greenhouse gas admixture (such as hydrogen sulphide, carbon monoxide), its calorific value ranges from 1917 to 1927 MJ / m3 (megajoules per cubic meter of biogas, in normal conditions, ie 0 ° C and 105 Pa),

depending mainly on the content of methane. Composition of biogas
