    The Coal Patrol: Coal to Synfuels: Deal or No Deal?

    BY //

    Synfuels’ political bubble has burst in Washington, but the market may step in where Congress fears to tread. When coal industry interests, in the form of the CTL Coalition, got a bill with strong federal support for coal-to-liquids technology before the Senate this spring, it appeared that the political skids were greased for some kind […]

    Lignite Drying: New Coal-Drying Technology Promises Higher Efficiency Plus Lower Costs and Emissions

    BY //

    The U.S. Department of Energy (DOE) and Great River Energy are testing a new coal-drying technology that could dramatically reduce the emissions of lignite-burning power plants. The project was selected for funding during Round I of the DOE’s Clean Coal Power Initiative (CCPI), a series of competitions to demonstrate a range of promising clean-coal technologies. […]

    Mercury Control: Capturing Mercury in Wet Scrubbers: Part I

    BY //

    Are you using your flue gas desulfurization (FGD) system to its highest potential? You might not be if you’re not making it do double duty. It seems that million-dollar wet scrubber you installed to rid your flue gases of sulfur dioxide also can do a decent job of capturing mercury — under the right conditions. […]

    Speaking of Coal Power: IGCC Sticker Shock

    BY //

    Former Illinois Senator Everett Dirksen once observed, “A billion here and a billion there, and pretty soon you’re talking real money.” The same can be said about skyrocketing estimated costs of integrated gasification combined-cycle (IGCC) plants as their designs are fleshed out. The higher price tags shouldn’t be a surprise — the more you learn […]

    Coal Plant O&M: Smart Sootblower Tailors Cleaning to Need for It / Blending’s Impact on Coal Quality

    BY //

    The 1990 amendments to the Clean Air Act require coal-fired power plants to reduce their emissions of the pollutant SO2. To do so, many have switched to, or are considering switching to, Powder River Basin (PRB) coal. Unfortunately, PRB coal has a tendency to leave excessive and tenacious deposits on boiler heat-exchange surfaces. Complicating the problem, the distribution of the deposits is far from uniform.
