Coal is widely used in our lives; however, it is not a renewable energy. How to reduce the pollution of the coal is becoming a popular concern in our society. In this article, I will present some background information about coal to show the disadvantage of the coal, I will then introduce you three promising projects, and show you some details about them. Although there is a long way before we can widely improve the use of the coal, these projects let the coal’s future be full of hope.
Coal is the largest source of energy for the generation of electricity worldwide. It is also a nonrenewable source in the earth. Although a lot of countries largely depend on the coal, they may not pay attention about how to reduce the pollution of the coal or improve the use of the coal. Today, we consume more coal the more pollutants will release into atmosphere. To fix that situation, I have examined some novel projects for almost 2 weeks.
Background of the coal
As Wiley Jenkins who holds the rank of Research Assistant Professor with the Southern Illinois University School of Medicine says Coal is produced across 25 states and provides 42% of US energy. With production expected to increase 7.6% by 2035(Jenkins 2).In order to determine whether the coal affect our health, they used systematic way to do the research and convinced us that the coal has large possibility to cause the cancer. Due to the disadvantage of the coal, I have found some novel projects that can make the coal use more efficiently. I will then present you some specific details about coal’s disadvantage.
Cancer Risks Associated with Coal Mining
Coal’s burning will cause large pollution to our environment; it plays a significant role in our energies. .Coal is produced across 25 states and provides 42% of US energy, with production expected to increase 7.6% by 2035 (Jenkins 2) Some scientists are focusing on whether coal mining will cause the cancer or not .To determine that, Jenkins’ team has performed a systematic review of the English-language manuscripts published since 1980 to determine if coal mining exposure was associated with increased cancer risk. They use eligibility criteria included; English language, peer-review, publication basis in human subjects, and examination of coal mining and associated or subsequent cancer of any kind (Jenkins 2). Although the assessment are too meager to determine the whether coal mining will cause the cancers, the widespread geographical extent of coal mining activity, and the continuing importance of coal for US energy, warrant further studies of population exposure and risk. Cancer Risk is probably associated with Coal mining. So I have found several projects could probably solve these problems.
The first project I found is a synthesis approach to improve the efficiency of Coal-Fired Power Station. The author Baraka Celestin Sempuga (the Director of the Department of civil and Chemical Engineering from University of South Africa) found that CO2 emissions could efficiently be reduced by using different chemical pathways to do the combustion or by combining power and chemical production. He suggests us a new way to improve the use of the coal-burning. The second project described by Yang Weijuan is to control the burnout of the coal by controlling the NOx emission in down-fired boilers. Yang is the director of Chemistry Department of Fuzhou University. The third project written by Vivek (the Director of the department of Chemical Engineering from Municipal college, Rourkela) is to conserve the energy in coal based sponge iron industry incorporating certain design modifications without disturbing the process technology.
