http:wwweuronewscom with over 300 days of sunshine per year ain beni mathar in morocco near the border with algeria was the perfect site to build a thermal and solar hybrid plant the first of its kind in africa ain beni mathar is a real opportunity for morocco to explore alternative sources the country suffers greatly from its energy dependence importing 97 of its coal and oil energy needsthe national office of energy and the african development bank have opened the doors of the plant to euronews on a guided tour the company039s chief operating officer nour eddine fetian told us: quotthe principle is that the plant consists of two lines two gas turbines two heat recovery steam generators one steam turbine and lines for production and energy discharge so steam is produced by two sources: there is natural gas under the normal combined cycle and the steam produced by the solar field both vapours converge towards the steam turbine and are integrated at the same time to produce electric powerthe total output of the power plant is 472 megawatts 20mw of which is solar allowing it to satisfy about 10 of the country039s energy demand ain beni mathar is supplied with natural gas by the maghreb europe pipelinefetian nour eddine the director of the beni mathar power plant also spoke about the intelligent energy recovery system: quotso the combined cycle recovers energy from the exhaust gases to produce steam basically after bring emitted the exhaust gas enters a recovery boiler the boiler is fueled by water and produces steam through heat exchangers this steam then reaches certain parameters of temperature and pressure to enter the steam turbine where it converges with the steam produced by the solar field to power the turbine and produce electrical energy through this mechanismquot the plant uses an innovative cooling system the giant fans are air-cooled condensers they reduce water consumption by 53 million cubic metres per year and from at least one million cubic metres per year there039ll be an 80 saving of waterthe plant039s director also explained how the cooling system works: quotsince it operates in a closed cycle the steam powering the turbine must condense and so we need a cooling system the system used in this plant is a dry cooling system which minimises water consumption so in effect it becomes an air-water exchanger through the fans it draws in fresh air and is injected into a heat exchanger to condense the steam recycle the water and resume the cycle early but most importantly it reduces water consumption by a very significant marginquotthe solar array occupies 88160 hectares of the site: the 3688 cylindrical and parabolic panels follow the sun039s path the site is a testing ground for morocco a 100 solar plant with a capacity of 2gw giga watt will soon come to ouarzazatefetian nour eddine director of the beni mathar iscc power plant said: quothere we have this parabolic format which allows the dish to track the exact position of the sun to maximise the radiation it quickly reflects the rays back toward the collector this is where you find a special tube that circulates the oil the oil recovers the maximum recovered energy of solar radiation and then transfers that heat to the recovery boilerquotthe plant meets strict environmental standards - allowing morocco to save 12000 tons of fuel oil per year to halt its energy dependence morocco has implemented plans to produce 40 of renewable energy by 2020find us on: youtube http:bitlyzr3upy facebook http:wwwfacebookcomeuronewsfanstwitter http:twittercomeuronews

biomass as a fuel for boilers
Bookmarked 693 weeks ago
http:crowncapitalmngtcomblogpdfbiomass_as_a_fuel_for_boilerspdf biomass for energy often mean plant base material although can equally apply to both animal and vegetable draw from material biomass is actually a biological material derive form living or recently living organisms biomass chemical composition is carbon based and is composed of a mixture of organic molecules containing hydrogen usually including atoms of oxygen often nitrogen and also small quantities of other atoms including alkali alkaline earth and heavy metals metals are often found in functional molecules such as the porphyrins which include chlorophyll which contains magnesium there are five basic categories of material of biomass such as:virgin wood- from forestry arboriculture activities or from wood processingenergy crops- high yield crops grown specifically for energy applicationsagricultural residues- residues from agriculture harvesting or processing food waste- from food and drink manufacture preparation and processing andpost-consumer wasteindustrial waste and co-products- from manufacturing and industrial processesthe question is how are we going to use this biomass as a fuel for boilers but what is a boiler in the first place a boiler is defined as quota closed vessel in which water or other liquid is heated steam or vapor is generated steam is superheated or any combination thereof under pressure or vacuum for use external to itself by the direct application of energy from the combustion of fuels from electricity or nuclear energy quotlet us then go back to the previous question how are we going to use this biomass as fuel for boilers nowadays the prime sources of energy in the world are oil coal and natural gas but these natural sources of energy has their end too unfortunately it is already anticipated that within the next 40-50 years these sources of energy will deplete worst is it is also expected that from these sources lies consequences due to their emissions such as global warming acid rain urban smog due to this fact the world is trying to utilize new sources of energy there are some renewable energy sources that can replace harmful energy sources the solar wind biomass etc are energy sources which are less harmful to the environment but can only be use in a suitable way biomass is one of the earliest ever discovered sources of energy but only comes with specific properties it was then discovered that utilizing biomass in boilers offers many economical social and environmental benefits such as financial net saving conservation of fossil fuel resources job opportunities creation and co2 and nox emissions reduction however care must also be taken for consideration although biomass can be good in some point there are also disadvantages such as: environmental impacts of biomass such as land and water resources soil erosion loss of biodiversity and deforestation problems associated when burning biomass in boilers are fouling marketing low heating value storage and collections and handling the future of biomass in boilers depends upon the development of the markets for fossil fuels and on policy decisions regarding the biomass market

minesto tidal energy
Bookmarked 783 weeks ago
minesto develops a new concept for tidal power plants called deep green deep green is based on a fundamentally new principle for electricity generation from tidal currents the power plant is applicable in areas where no other known technology can operate cost effectively due to its unique ability to operate in low velocities minesto expands the total marine energy potential and offers a step change in cost for tidal energythe principle of the technology can be explained as a two stage process the first stage increases the relative flow speed entering a turbine when the tide hits the wing it creates a lift force since the kite is mounted to the ocean bed with a tether and is controlled by a rudder the kite can be taken in the desired trajectory here in an eight formed path the method increases the flow velocity into the turbine by 10 times compared to the actual stream velocity the second stage uses a generator to convert kinetic energy into electrical powerthe net result is increased power from a smaller package the planned normal full size weighs only 7 tons excluding anchoring which gives an energetic payback time of 3 weeks compared to 8 months for onshore windthe test confirms power production of the plant at marin in holland

though highly flammable it still has good safety credentials at least from a pollution perspectivesafety lpg is non-toxic and a leak of lpg vapour is unlikely to pose any significant ground or water pollution hazard as a liquid it is lighter than water so has the environmental benefit of always remaining above the water level any lpg spillages simply vaporise and do not cause soil or water contamination
