What Are The Advantages And Disadvantages Of Gas Turbine

Water turbines are near the oldest ways to run power without using fossil fuels. The new age had turned these into hydro turbines that generally reside in dams. These machines take similar shape to wind turbines. Hidden in the base of a dam, there is a very large turbine that, in a simple explanation, when water runs through it spins. With the energy used by the spinning turbo it is turned into different power sources that are stored into power cells. Way back in time, this idea was used in power mills. Those old spinning wheels on the side of houses that rotate with water pressure. The first power plant was constructed in 1879 at Niagara Falls, Canada. In the United States the first plant was in 1882 in Wisconsin. These extravagant machines seemed marvelous, but that is no longer the outcome. The current age hydroelectricity dams are currently being shut down for harmful aspects triggered from the giant production. Causing an environmental failure to marine life and habitats all around. The possible outcomes are: changing the oxygen levels in the water that cause organisms to perish; fluctuating water levels that cause different

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the

These turbines are connected to the compressor and also the fan. So basically when turbines rotate, the compressor and the fan also rotate. What happens is that the airflow coming from the combustion chamber makes the turbines rotate and as the turbines rotate, they also make the fan and the compressor spin. Finally the gases exit through the nozzle.

In 1831, scientist Michael Farday discovered the first form of electricity. He found that when a magnet moved inside a copper coil it created what is known as an electric current. This invention is known as a turbine generator. Even today, in full sized power stations this simple invention is still used and works very effectively. These power stations create mass amounts of energy to turn the turbines. Most of the time the energy is made from the heat, for example when coal is burned. More environmentally friendly power stations use wind or flowing water to turn these turbines. This is known as renewable energy because it will not run out, unlike when oil and coal are used.(3)

The main components of a windmill consist of blades, rotor and generator etc. The blades are the most important feature of the wind turbine. It looks like sails, normally have two or three blades, they are aerodynamically shapes to make the most of the energy in the wind, turning a shaft which is connected to a generator and turn into wind power. When the wind forces the blades to move, it has transferred some of its energy to the rotor which is the technical term for the entire hub. It is also known as a propeller. The rotor usually consists of two or more wooden, fiberglass or metal which rotates about an axis at a rate determined by the wind speed and the shape of the blades. In addition, rotor can turn a generator which transforms the mechanical energy into electricity. There is an electric motor orientates the nacelle so that, rotor is positioned facing into the wind. In terms of generator, that is converts the motion of wind turbine in to electricity. A simple generator consists of magnets and a conductor. The conductor is typically a coiled wire, they are rotated in a magnetic field to produce electrical voltage. The shaft connects to permanent magnets which surround by coils of wire. In the electrical process, when the conductor that has magnets rotating to the other, there is an electric

Wind turbines are not flawless, they do have some problems. One of the first problems is the limitation of wind power. Scene the turbines rely on wind to generate electricity if there is no or vary little wind

The main cost of wind energy is in the initial investment in the construction of a wind turbine; the upkeep cost is generally marginal and lower than one cent per kWhr. In general, wind power works by having air molecules move across the turbine blades transferring kinetic energy from the molecules to the turbine, causing it to turn. As it turns, the mechanical energy can be used to perform tasks such as grinding grain. More commonly, the turbine turns and utilizes a power generator to convert the mechanical energy to electrical energy.

THE ADVANTAGES AND SHORT COMINGS OF GAS VERSUS LIQUEFIED NATURAL GAS (LNG) CASE STUDY : USA

Non Conventional energy resources like wind, biomass, tidal /wave and small hydro potential were used due to fast depletion of fossil fuels. A micro-hydro system using natural hydro potential with minimal civil works is a strong candidate in this race. However, the system must be economical, rugged, and user friendly since local communities are often not techno-savvy. Uncontrolled low head turbines are prescribed for such applications [1]-[5], which maintain almost constant input power due to fixed head and discharge. In remote locations, harnessing of electrical energy from such local resources can be cheaper and easier compared to grid connection, which involves long transmission lines and associated

Turbine is used as steam driven to convert heat energy to electric power in thermal power plant. Coal is burnt in a boiler to convert water into steam. By using Rankine cycle concept, the steam is expand in turbine to produces mechanical power, where the energy is transferred by a force to drives the alternator coupled to the turbine. Then after the steam is passed through turbine, the steam is condensed in a condenser to convert into liquid and recycled to its original temperature in vapor state. The energy efficiency of a conventional thermal power station is typically 33% to 48%. The figure 1 shows the general layout of the thermal power plant and the figure 2 illustrates the components of the thermal power plant.

Erosion corrosion is the combined effect of corrosion and erosion, which is caused when a rapid turbulent fluid passes through the metal surface [1], which are already corroded by pits. The pits are formed because of the breakage of the oxide layer of the metal. A combination of erosion and corrosion can lead to very high pitting rates. The joint action of the erosion and corrosion is known as erosion-corrosion, which is encountered prominently in chemical processing industries like oil and gas and power plants. The joint effect of erosion and corrosion is significantly very much higher than that of the effects of erosion and corrosion when it acts separately. Thus erosion and corrosion have a synergetic effect on each other, which is why the phenomenon is often grouped together as one. A critical fluid velocity must be exceeded for a given material for the erosion corrosion to occur. The fluid which impacts on the material causes disruptive shear stresses or pressure variations on its protective surface film, which causes the mechanical damage of the material. Erosion corrosion is accelerated at pipe elbows where there is sudden change in geometry of the pipe design, tube constrictions and wherever the fluid flows are changed or on anything which results in the turbulent increase.
