Clean Coal Technologies 

In some states where coal is in abundant supply, the coal is the primary raw material used to produce electricity. The process of generating electricity occurs in several stages:

• Coal is burned in a large boiler to make high-pressure, high-temperature steam.

• The steam is passed through a turbine.

• The turbine converts the thermal energy in the steam to mechanical energy.

• The spinning turbine then drives the generator to produce electricity.

During the course of power generation with coal, pollutants are emitted into the atmosphere. The three main pollutants that are emitted into the atmosphere that can be detrimental to the environment are nitrogen oxides, sulfur dioxide, and particulates. Specialized equipment is typically used at different points throughout the steam generation process to minimize emissions from the power plant:

• The first step in reducing emissions occurs by utilizing a low nitrogen oxides (NOx) burner to burn the coal. The equipment regulates the rate of combustion of the coal by controlling the amount of air available at different elevations within the boiler to complete the combustion. This process adjustment results in lower NOx emissions.

• In the second step, the flue gas is passed through an electrostatic precipitator (ESP) after it exits the boiler. In the ESP, a series of positively charged collection plates remove negatively charged particulate matter from the flue gas. The ESP captures more than 99 percent of the particulate matter in the flue gas.

• For the third step, a scrubber is used to control the sulfur dioxide compound in the flue gas. These are water-soluble compounds in the emissions. As the flue gas passes through the scrubber, it is mixed with limestone slurry in water. The limestone reacts with the flue gas and absorbs the sulfur dioxide in the flue gas.

Discuss additional current technologies for emission controls for coal-fired electricity generation facilities. Are the above emission control devices enough? Are there other cost-effective process changes or raw material processing operations that can either add to, or have the same effect as, reducing pollutant emissions from these types of plants? What additional clean coal technology (before, during, and after the combustion process) can be considered or used to further reduce emissions? Are carbon capture and storage technologies available for coal-fired plants? Discuss the economic feasibility and the overall benefit, if any, of adding these technologies.

Your response should be in APA format including a title page and a reference page. An abstract is not required for this assignment. The body of your paper (not including title or reference page) should be approximately 2-3 pages.

Use of Sources (worth a maximum of 20% of the total points). Zero points:  Student failed to include citations and/or references. Or the student failed to submit a final paper. 5 out 20 points:  Sources are seldom cited to support statements and/or format of citations are not recognizable as APA 6th Edition format. There are major errors in the formation of the references and citations. And/or there is a major reliance on highly questionable. The Student fails to provide an adequate synthesis of research collected for the paper. 10 out 20 points:  References to scholarly sources are occasionally given; many statements seem unsubstantiated.  Frequent errors in APA 6th Edition format, leaving the reader confused about the source of the information. There are significant errors of the formation in the references and citations. And/or there is a significant use of highly questionable sources. 15 out 20 points:  Credible Scholarly sources are used effectively support claims and are, for the most part, clear and fairly represented.  APA 6th Edition is used with only a few minor errors.  There are minor errors in reference and/or citations. And/or there is some use of questionable sources. 20 points:  Credible scholarly sources are used to give compelling evidence to support claims and are clearly and fairly represented.  APA 6th Edition format is used accurately and consistently. The student uses above the maximum required references in the development of the assignment. Grammar (worth maximum of 20% of total points) Zero points:  Student failed to submit the final paper. 5 points out of 20:  The paper does not communicate ideas/points clearly due to inappropriate use of terminology and vague language; thoughts and sentences are disjointed or incomprehensible; organization lacking; and/or numerous grammatical, spelling/punctuation errors  10 points out 20:  The paper is often unclear and difficult to follow due to some inappropriate terminology and/or vague language; ideas may be fragmented, wandering and/or repetitive; poor organization; and/or some grammatical, spelling, punctuation errors 15 points out of 20:  The paper is mostly clear as a result of appropriate use of terminology and minimal vagueness; no tangents and no repetition; fairly good organization; almost perfect grammar, spelling, punctuation, and word usage. 20 points:  The paper is clear, concise, and a pleasure to read as a result of appropriate and precise use of terminology; total coherence of thoughts and presentation and logical organization; and the essay is error free. Structure of the Paper (worth 10% of total points) Zero points:  Student failed to submit the final paper. 3 points out of 10: Student needs to develop better formatting skills. The paper omits significant structural elements required for and APA 6th edition paper. Formatting of the paper has major flaws. The paper does not conform to APA 6th edition requirements whatsoever. 5 points out of 10: Appearance of final paper demonstrates the student’s limited ability to format the paper. There are significant errors in formatting and/or the total omission of major components of an APA 6th edition paper. They can include the omission of the cover page, abstract, and page numbers. Additionally the page has major formatting issues with spacing or paragraph formation. Font size might not conform to size requirements.  The student also significantly writes too large or too short of and paper 7 points out of 10: Research paper presents an above-average use of formatting skills. The paper has slight errors within the paper. This can include small errors or omissions with the cover page, abstract, page number, and headers. There could be also slight formatting issues with the document spacing or the font Additionally the paper might slightly exceed or undershoot the specific number of required written pages for the assignment. 10 points: Student provides a high-caliber, formatted paper.
