  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Coal-fired power on the way out?

    The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

  • The Great Transition – Closing Coal Plants

    We may wake up one morning in the not-too-distant future and realize that the world has reached a tipping point on coal. So concludes the Earth Policy Institute in Chapter 3 of its upcoming report entitled The Great Transition: Shifting from Fossil Fuels to Solar and Wind Energy. Use of this fuel will be declining worldwide, as ...

  • Air Quality Permitting for a New Coal-Fired Power Plant: A Timeline

    The high price of natural gas and alternative fuels has made utility companies take a second look at coal as a cheap, plentiful fuel source. For a greenfield plant considering coal, the environmental considerations are significant but not insurmountable. This article discusses the air quality regulations and permitting requirements that must be addressed, from New Source Review to greenhouse gas ...

  • Coal fired power plant achieves ZLD for FGD wastewater

    The Facility Illinois’ City of Springfield’s Dallman Power Station’s three coal-fired units and soon to be installed fourth unit, are equipped with flue gas desulfurization (FGD) systems (scrubbers) to control sulfur dioxide (SO2) emissions. The Problem A sharp increase in boron concentration in the FGD wastewater required that The City ...

  • Thermo-economic efficiency of low capacity coal-based power plants

    The method of estimation of thermo-economic factors, allowing the justification of the construction of low capacity coal-based power plants has been developed in the present paper. The C-curve method applied for thermo-economic analysis is used here for determination of the optimal ratio between specific exergetic and cost-performance factors. The results of the analysis show that for coal-based ...

  • A new way to measure emissions from China’s Coal-Fired Power Plants

    To prevent the most severe impacts of climate change, it is essential to limit fossil fuel use—particularly coal use in power production. The share of coal in global energy consumption is increasing, with ...

  • Exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant

    This paper presents exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant using specific exergy costing (SPECO) methodology. Cost–balance and auxiliary equations are developed and solved. The results indicate that in the topping cycle, the boiler and the turbine contribute maximum to the formation of product cost. High value of exergoeconomic factor for the boiler ...

    Untitled Document Mercury is a hazardous air pollutant (HAP) that circulates around the globe for a year before depositing back to ...

  • Cleaning the Air We Breathe, Coal Fired Power Plant - Case Study

    By cleaning flue gases from coal power plants, the amount of environmentally hazardous emissions can be sharply reduced. Mist elimination from Munters is a critical part of this process. Munters has worked with leading power generating companies for decades and have through testing and follow up built an extensive parameter database and design tool to be able to adapt and optimize results based ...

  • Techno-economic evaluation of revamping of coal-fired power plants in India

    A techno-economic feasibility study has been conducted to investigate the revamping of two 32 MWe Pulverised-Coal (PC) boilers with a number of firing options. The options investigated were: (1) conventional PC revamping, (2) replacement with a new PC boiler, (3) PC to Circulating Fluidised Bed (CFB) revamping, (4) replacement with a new CFB boiler, and (5) Bubbling Fluidised Bed (BFB) revamping. ...

  • Closing the door on building new coal-fired power plants in America

    Community opposition, legal challenges, and financial uncertainty over future carbon costs are prompting companies to rethink their plans for coal. Since the beginning of 2007, 95 proposed coal-fired power plants have been cancelled or postponed in the United States--59 in 2007, 24 in 2008, and at least 12 in the first three months of 2009. This covers nearly half of the 200 or so U.S. coal-fired ...

  • Opportunities to improve the efficiency of existing coal-fired power plants

    Executive Summary Reducing the carbon footprint of energy production activities has emerged as one of the defining environmental issues of the 21st century. The U.S. energy infrastructure encompasses an enormous investment in capital assets and systems to produce fuels and electric power for businesses, transportation, and homes. While the long‐term opportunity to reshape this ...

  • Methylmercury in mosquitoes around a large coal‐fired power plant in Central Ohio

    Emissions from coal‐fired power plants are the major anthropogenic source of mercury (Hg) in the environment. Because emitted Hg can be deposited near the source, concerns arise about the effects of coal‐burning facilities on levels of toxic methylmercury (MeHg) in biota near such sources. We investigated the potential impact of a large Hg‐emitting (450 kg in 2005) coal‐fired power station in ...
