Advantage and Disadvantage of Steam Turbine Plant Steam turbine plant is commonly used in marine propulsion as it generate electricity through the rotation of the turbines that rotate because of the steam forces. In this case, no matter what type of plant and systems used in marine propulsion, they have several advantages and disadvantages.
The Advantages
No Frictional Loose The usage of the steam turbine can bring benefits to the user as it has no frictional loose that usually bring problems to the reciprocating engine as it must always be maintained. (Prasanna, n.d.)
Less Space Usage Steam turbine plant does not usually used more space than other plant. This is because the working principles of the steam turbine plant does not need

According to picture 2, heat exchanger (air heater) wills heater the compressed air from the surroundings (Mechnol, n.d). Therefore Closed Cycle Gas Turbine not need starting motor for generated 1st power cycle. The heat additionally given to the heat exchanger for constant the pressure from the external source. The power developed by high pressure working fluid increases over the turbine. The temperature of the exhaust working fluid is high; therefore it must be cooled in a pre-cooler. Process is done when same fluid as the starting cycle is sent back into the compressor. In the turbine same working fluid is always distributed. The fuel ranges from kerosene and then to the heavy oil is required for adding heat. The coal slurry enters the turbine without reducing the efficiency (Mechnol, …show more content…
Then, the spinning turbine blades rotate the turbine shaft which is connected to a generator. From the kinetic energy transfer to the mechanical energy by turbine shaft. The rotating of turbine shaft will affect the generator to power electrical energy (PowerGeneration, n.d).
Advantages of gas turbine plant.
Storage of fuel requires less area and handling is easy. Next, the cost of maintenance is less and it is simple in construction. There is no need for boiler, condenser and other accessories as in the case of steam power plants. Thus, cheaper fuel such as kerosene and paraffin, benzene and powdered coal can be used which are cheaper than petrol and diesel. In addition, gas turbine plants can be used in water scarcity areas and less pollution and less water is required (Dhiman, 2014).
Disadvantages of gas turbine plant
66% of the power developed is used to drive the compressor. Therefore the gas turbine unit has a low thermal efficiency. Second, the running speed of gas turbine is in the range of (40,000 to 100,000 rpm) and the operating temperature is as high as 1100 – 12600C. For this reason special metals and alloys have to be used for the various parts of the turbine. Third, high frequency noise from the compressor is
Power plants burn fuel to produce heat to generate energy; however, nuclear power plants use the heat given off fission to turn water into steam. Nuclear energy is without a doubt a great way to power our homes because, Nuclear power plants are safer than other energy alternatives. Nuclear plants are safer than other energy alternatives. Coal is responsible for five times more deaths than nuclear power plants, coal also causes over one thousands more serious causes of illness than nuclear. Nuclear plants produce steam while coal plants, heat water by burning coal that produces greenhouse emissions.
Over 20 percent of the energy in the United States comes from nuclear energy power plants. (Rinkesh, 2018) They so their best to get as much energy to the country as possible, but there are those out there who don’t agree with them. While there are downsides to nuclear energy, the pros vastly outweigh the cons. Nuclear power plants are a great way to get energy because they don’t let out much pollution, are very efficient, and are very safe.
The history of steamboats is quite interesting. Back before cars and trains existed, rivers were used for trasportation. The travels they often took were slow because speed of travel depended on the river current, and manpower. That is, until, the 1800s where steamboats could reach up to speeds of 5 miles per hour. After they realized they could reach such speeds, the men started river travel and trade.
Given the information provided in the film, I believe electric cars are a reasonable alternative to combustion engines because they don’t produce harmful emissions like gasoline cars do. According to the film, even the first electric cars were quiet, fast, and produced no exhaust. This is a clear advantage over combustion engines, which produces exhaust that contains carbon dioxide, carbon monoxide, and nitrogen oxide. Not only do they produce no emissions, but electric cars do not need as much maintenance as combustion engines do. This is due to the fact that there are no spark plugs or oil to be changed.
Wave Energy Wave energy is a great alternative energy to fossil fuels. When people think of waves, they usually think of surfing, the beach, waves crashing down on the shore, but most people don’t think of energy being converted through waves. This energy is very unique, and more people should know about it, and should definitely be used more. Ocean wave energy is a good alternative to fossil fuels, because is renewable, a powerful clean source, and there are multiple options of ways to harness it. How It Works
6. Steam Generator. It forms a portion of the cooling system of pressurised water reactors. The high pressure primary coolant transfers the heat from the reactor and is used to generate steam in a secondary
Fracking is one of the many controversial topics in resource production. The procedure can harm the environment, but can help the economy and the oil industry. The main reason the procedure is so controversial is that it uses too much water, it may leak chemicals and contaminate groundwater, it can raise the amount of gas used, and it may cause earth tremors. There are also many advantages to fracking, but can affect the environment but can help the economy. My views on fracking are positive for there are many more advantages to the process.
It used up a lot of coal that was burned in a firebox to heat it and get the steam running so it starts
Then the liquid carbon dioxide, or liquid nitrogen, is put into a block press or a pelletizer. these two things are meant to press together items to make new items. These machines have chambers in which, once released to the atmospheres pressure, it then turns into dry ice snow. it can also make carbon dioxide gas. they then re-capture the released gas, and do the process over again.
the refrigerant is in a high-pressure, gas state. With the help of the A/C fan, the refrigerant cools as it moves through the condenser. During this process, the condenser pressurizes the gas and turns it into a liquid before it reaches the evaporator. Chevrolet C1500 Evaporator: When the refrigerant is in its liquid form, it expands.
For instance, the stoves we use to cook our food run on gas, so does the heat water for our daily showers. In addition, to dry our clothes we use natural gas and for cars owners, we use gas or diesel to get from point a to point b. The U.S Energy Information Administration (EIA) states that natural gas has many qualities that make it an economical energy source. However, there are environmental issues associated with the production and use of natural gas (EIA, 2014).
The development of the stationary steam engine was an essential early element of the Industrial Revolution. The world was becoming an industrialized place before the advent of steam power, but would never have progressed so quickly without it. Factories that still relied on wind or water power to drive their machines during the Industrial Revolution were confined to certain locales. Steam meant that factories could be built anywhere, not just along fast-flowing rivers.
The gas (gasoline) division is advance cultured and through an assortment of procedures is changed over into the fuel we control our autos with, warmth homes, and cook our nourishment. Certain parts of the gas division are evacuated (depentanized) and others have their substance structure changed (isomerized). A couple dirtying impacts are cleared (desulfurized), and others have portions added to convey the last thing (reformulated fuel).
Wind energy is mainly used to generate electricity like earlier wind mills modern wind machines used blades to collect the winds Kinetic energy. 1.1.1 Advantages 1) The blades ere connect to shaft that turn on an electric generator to produce electricity. 2) Use of wind power to produce electricity on commercial scale has become the fastest growing energy technology. 3) Wind energy is comparatively labor exhaustive and as a result creates
Very large amounts of electricity can be generated in one place using coal, fairly cheaply. Transporting oil and gas to the power stations is easy. Gas-fired power stations are very efficient. A fossil-fuelled power station can be built almost anywhere o Disadvantages of Using Fossil Fuels Basically, the main drawback of fossil fuels is pollution.
