Negative Impacts of Coal and Clean Coal Technology Research Paper

Negative Impacts of ember and blank Coal Technology - Research Paper ExampleDifferent types of coal atomic number 18 found within the Earth in collective form which be then extracted and utilise for different purposes (The formation of Coal Planete Energies ). CLASSIFICATION Classification of coal is done on the basis of transformation of the instals. The more transformed plant material the better is the form of coal. The type of coal is determined by a process cognise as Proximate Analysis. In this process the constituents of coal are analyzed for classification. Various constituents of coal are water, volatile substance, carbon and dust. Coal is mainly classified on the basis of carbon sacrifice in it and the relative heat energy it can produce. There are two companys of coal sink rank consists of lignite and sub-bitunimous and the prouder rank consists of bitunimous and anthracite. Lower rank coal has low carbon and energy levels. They are soft and friable in nature wit h somewhat brownish appreance. The higher rank coal has high carbon and energy level. They are hard and strong in nature with complete sable apprence. However, along with coal, peat is also present with is not classified as coal because of its characteristics yet it plays a very substantial office in the formation of coal (The Energy Library Types of coal). Peat It is not coal but it is connect to the process of formation of coal. It has a soft apprence and it consists of deposited plant substances along with other chemicals. They are present in the wetland areas of Northern Hemisphere. Lignite It is also known as brown coal because of its apprence. It contains upto 60% carbon and 50% volatile substance. It can not produce high level of energy and therefore it is not traded in the market. It is usually utilise in power stations and industry boilers which are close to the coal mines. Since it has a soft texture therefore it is easily converted into gas or petrolem. Sub-bitunimou s Next layer afterward lignite is of Sub-bitunimous coal which is formed by the plant fossils that are burried deeper in the soil. It is hard and dark in color as compared to lignite and it can produre high level of clean energy as it has lower sulphur composition. Bitunimous It has upto 80% carbon and produces higher level of energy. It is also known as sedimentary shake because it possess deeper plant fossils and minerals. It generates smoke and dust when burned. The appearance of the coal is either dark brown or black with fine texture. It is significantly used in electric producing plants and industries and it is very appropriate for steel making. anthracite coal It is ranked as the highest type of coal because it contains higher level of carbon. It is very hard and completely balck in color. It produces less smoke and lower flame. Anthracite is also known as blue coal, stone coal, black diamond, etc. It is found usually in the mountain ranges. USES Coal is substantially requ ired to fulfil the present and future energy demands. Following are the most important uses of coal (World Coal Association uses of coal) It is used as liquid fuel in production of steel, cement and electricity. Coal plays a major role in paper manufacturing, chemical industry, pharmaceutical sector and in rifnery of aluminia. The coal by-products are also used in production of certain chemicals. Coke ovens produces Amonia gas which is then used to produce ammonia salts, ferilizers and acids. Products of insouciant usage such as soap also contains coal.
