  • 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 ...

  • Flue gas Hg measurements from coal-fired boilers equipped with wet scrubbers

    The U.S. EPA has indicated they are considering additional SO2 and NOx emission reductions, and EPA is under a consent agreement to propose mercury reduction regulations by 2004 for the utility industry. The boiler manufacturers and the utility industry have developed improved combustion modification techniques to reduce NOx emissions. These advanced ...

  • 5th-Generation Thermox WDG Flue Gas Combustion Analyzer

    "For more than 40 years, we have been a leader in combustion gas analysis," says Mike Fuller, divison VP of sales and marketing and business development for Ametek Process Instruments, "and we believe the WDG-V is the combustion analyzer of the future." WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as ...

  • Dry regenerable sorbents for the separation and capture of CO2 from large point sources

    The combustion of fossil fuels generates large quantities of carbon dioxide (CO2), a greenhouse gas most likely to influence global warming and climate change. Large stationary sources that include coal-based electric generating stations are plausible targets for the removal of CO2. Chemical absorption of CO2 is viewed as one option that could be applicable ...

  • Mercury Control Demonstrations

    C1.1 | Halogens and Sulfur in Coals and their Influence on Co-benefit Mercury Capture Bernhard Vosteen | President, Vosteen Consulting Gmbh Not only the range of the coal mercury content itself, but also the range of the native halogen and sulfur contents in coal are of great influence on co-benefit mercury capture, wet and dry. The ...

  • Capture of carbon dioxide from flue gas using solid regenerable sorbents

    Carbon dioxide emissions from the combustion of fossil fuels are a significant factor in global climate change. Large stationary sources such as coal-fired electric generating plants are likely to be the most cost-effective targets for carbon dioxide capture. At present, liquid amine-based scrubbing systems are the only processes available for this application. Processes based on regenerable ...
