High-volatile bituminous coal due to its high volatile matter content generates high pressure during carbonization which is detrimental to the coke oven walls (Nasirudeen and Jauro, 2011). A range for coking coal is 27.5 – 31.5 % volatile matter. It is one of the most important parameter used in ISO classification of coals. The volatile matter indicate coke yield on carbonization process, which provide basis for its marketability as well as for establishing burning characteristics of coal (Adeleke et al., 2007). Based on the plastic properties of the coal samples, it is observed that the volatile matter of the samples increases inversely with temperature range and maximum fluidity.
Over the past half-decade, the world has known a near-exponential increase in the consumption fossil fuels. It plays a quintessential role in the proper functioning of the globe. However, over the past few years, oil reserves have been depleting at a quick rate. There will be a day when there will not be any fossil fuels left to assuage the energy needs of the world. There is currently a few alternative resources lined-up but the most promising for fossil fuels to pass the torch to seem to be nuclear energy.
Coal is a nonrenewable resource that is part of the fossil fuel category that includes oil and gas, and it remains a vital source of energy for both industrialized and developing nations. As the world’s population grows, and industries continue to expand, the demand for energy will only increase. The accumulation of gases and waste from these carbon-based nonrenewable resources, particularly coal, has led to the greenhouse effect and other adverse consequences, to the point where the world’s
The overconsumption and overutilisation of mundane resources has led to them being diminished too quickly. Human activities such as the combustion of fossil fuels and deforestation have led to drastic climate changes. This is due to the greenhouse effect - when the atmosphere absorbs heat and the excess is not radiated into space. The greenhouse gases are responsible for this effect - carbon dioxide, water vapour, methane, nitrous oxide and chlorofluorocarbons. In the Caribbean, electricity production uses a huge amount of fossil fuels and this makes power companies one of the largest contributors to global warming and climate change in the region.
Good morning chairperson, timekeeper, opposing team and audience. The topic of today 's debate is South Africa should stop using coal to generate electricity and start using alternative energy sources. We on the positive team agree with the definition given that South Africa should stop using coal to generate electricity because coal is a flammable black hard rock thats contains 65% carbon dioxide.This means that when burning this rock, it releases all the carbon dioxide into the environment.Using coal energy is bad because the impact of this fossil fuel on our health and our atmosphere is one dirty, expensive proposition. Coal emits more carbon per unit of energy than oil, and 80 percent more than natural gas. It accounts for 43 percent of global emissions.
The world’s one of the biggest problems faced in the 21st century is to supply safe energy. Today, countries produce and use energy is not a sustainable way. Consumption of energy incerased by 40 percent between the years 1990-2008.At the moment 85 percent of global energy produced from fossil fuels(Irena,2011). These conventional energy sources such as coal and oil are the main problem for our world. Dependency on conventional energy sources make many negative contributions to our planet.
Introduction Coal mining is not a profession that you vision about or get a degree for. The individuals who are coal miners do not selected a life full of danger and suppression, they get trapped with it. There are many threats that come along with coal mining, not simply for the workers, but for the environment. Coal mining and the coal industry have triggered permanent damage to environment. Coal is referred to as fossil fuel that traces back to early times.
and Nuclear power. These Non-Renewable energy sources are cheap and limited on the earth, it converts the chemical energy to electric energy but emits harmful pollutants like Carbon dioxide and Carbon monoxide in the atmosphere. Today with the available technology, most of the energy production is hazardous for the environment and due to which world is suffering from serious pollution crisis. Every year more than 3 million people die worldwide due to Air pollution while most of the pollution released in atmosphere are from the power plants, industries and vehicles and other major impact caused due to fossil fuels is on environment, the
This leads to the production of nuclear energy (World Nuclear Association). China is one of the largest country that is investing in the renewable energy sources. The amount of energy is rapidly increasing, such as solar and wind energy from 74% to 34% (Hill, Joshua S). The solar power is produced from the sun’s heat reflecting and storing to the reservoir, wind power by spinning the turbines through wind and generating energy, hydropower through the water flow, biomass and biofuel through the leftovers and waste that is burned, geothermal through bed magmas heating the water and creating energy. These renewable energies are beneficial for the protection of environment and the
CHAPTER 2 LITERATURE REVIEW 2.1 Introduction Diesel fuel is the singles largest source to power vehicles both in transportation and agriculture sectors. For many decades, the world’s energy production has relied mainly on non-renewable crude oil derived from fossil fuel. The availability of fossil fuel is limited, out of which about 80% is estimated to be consumed for energy and transportation. Due to increase in consumption of fossil fuel since few years, a strong threat to clean environment is being posed as the burning of fossil fuel is associated with emission like CO, CO2, SOX, NOX, and particular matter. Which are major causes of air pollution?
