The high ash content is also an indication of low degree of coalification and hence immaturity of the coal (Onoduku, 2014). According to Lin et al. (2011), original coal ashes contain various kinds of minerals; coexist as crystal and non-crystal minerals at different temperatures. The agglomeration of ash may be influenced by parameters such as the chemical composition, particle size, size distribution, bed temperature, atmospheric condition (Haykiri-Acma and Yaman, 2013) and the content level; which in turn affects the operation of blast furnace and cupola. Industrial experience indicates that a 1 weight percent increase of ash in the coke reduces metal production by 2 or 3 weight percent (Price et al., 1997).
These methods are both economical and effective in helping reduce nuclear waste and it also adds in energy production thus creating an economical front for the country. In total countries such as the UK, Russia and Belgium are producing more than 1000 tons annually and they have been running the plants for the last 3 decades. However, once the waste has been reprocessed it cannot be recycled again. Thus now it has to be disposed and a good system of nuclear waste management is need for the USA. Countries such as Japan and Russia have been taking this reprocessed nuclear waste and used it as fresh fuel for other industrial
Since the discovery of fire until late 19th century , human beings relied on renewable energy as an essential part of their life .The present world is moving quick towards improvement of human progress. Enterprises, manufacturing plants, control plants, different government foundations, logical establishments, private associations are experiencing childhood with the premise of accessible characteristic vitality sources. Be that as it may, these sources are restricted and costly. Fossil fuels are the fundamental sources that are being utilized to deliver vitality today. They are quick draining as well as polluting the earth, and influencing the financial soundness of numerous nations.
For example, in the Industrial Revolution during the 19th and 20th centuries, coal is known to be the primary source of energy. Today, coal is still being used particularly in China, as it is a major source of energy in China. Other forms of mining commodities are also widely used as a basic element to produce many kinds of industrial goods.
Carbon dioxide can be used to both increase pressure in the reservoir and to reduce the viscosity of the oil. Carbon dioxide is the gas used most widely in the United States for this process and accounts for fifty to sixty percent of enhanced oil recovery. Carbon dioxide enhanced recovery began in areas which have natural carbon dioxide deposits, and therefore, this enhanced oil recovery technique could only be used near these deposits. Currently, new techniques are being created so that other industries can capture their carbon dioxide waste product, then this carbon dioxide can be used in areas that do not have natural carbon dioxide reservoirs. As a result, the use of carbon dioxide enhanced oil recovery is expected to increase.
Nowadays, we can’t deny that as the rapid development of economic globalization, newly high-technologies have become the competitive nucleus of comprehensive national power among world countries. The development of nuclear can improve the energy technology. The researches show that the nation’s nuclear power capacity is very likely to reach 80 gigawatts by 2020. It is a big step up from the 11 gigawatts in 2010.China currently has 15 reactors in operation, and 26 more under construction. It is the largest project in the world.” The country is still putting more efforts into personnel training, technological research and security checks” (Professor Guo Xiaobing).
It has 7m tall coke oven batteries. The company uses discriminatory crushing of coal to increase the coke quality. Coal is transformed into coke by heating the equipped coal blend in lack of air at a temperature of 1000-1050 degree Celsius for almost twenty hours. Nitrogen gas is used in dry quenching of coke. It produces power from the waste heat that is recovered at Back Pressure Turbine Station.
1. Introduction 1.1 Problem Background For years, the Internal Combustion Engine has been around, the use of ferrous alloys as its crank is mostly common. Because of the reliance on fossil fuel, these internal combustions need to be sustainable. Although efforts of finding alternative platforms for power generation like electricity and hydrogen fuel cell, these are still far in terms mass production readiness and affordability compared to the Internal Combustion Engine. To sustain remaining fossil fuels, a more efficient design must be considered in designing the crankcase for Internal Combustion Engine.
When the rods are entered into the reactor they are put under extreme temperatures till the atoms within the uranium begin to split creating a large excess of energy or in other words heat. As heat is released from the fission it boils water inside the reactor creating steam that steam is then collected by a generator and turned into usable energy that people can use. While nuclear energy does have some disadvantages like any power source there are also tones of advantage to nuclear energy. “The production of electric energy is continuous. A nuclear power plant is generating electricity for almost 90% of annual time.
Carbon dioxide is mainly produced by burning of fossil fuel either by cars or factories. Humans need a way to reduce the concentration of CO2 in the atmospheric. By using carbon dioxide as the gas source in enhanced oil recovery, we can reduce CO2 that being is being released to the atmosphere. However, every method has its own respective negative impacts too. Thus, by using carbon dioxide enhanced oil recovery, oil and gas companies can increase the oil production and reduced the emission of carbon dioxide into atmosphere but it will also lead to increase in investment.
