July 1886 POWER reported on the latest steam engine technology offered to the power generation market, this time by France. The Boulet engine (Figure 1) was described as a “French horizontal compound condensing receiver engine, having cranks at right angles, cylinders side by side, and live steam jacket. The valves are double slides, giving small […]

  The Federal Energy Regulatory Commission (FERC) recently issued major rules that address for the third time “discrimination” issues remaining after FERC’s 1996 landmark Order 888, which ushered in mandatory open access to transmission. The order was intended to give all power sellers equal access to power lines and thus increase wholesale price competition. Earlier […]

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 […]

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. […]

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. […]

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 […]

Lawrence Energy Center (LEC) proudly hosted about 60 representatives of the Powder River Basin Coal Users’ Group (PRBCUG) at its July 24th open house, luncheon, and plant tour. LEC was named the PRBCUG’s 2007 Plant of the Year at this year’s ELECTRIC POWER Conference and Exhibition in Chicago, May 1 – 3. Traditionally, the winning […]

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.

James Thurber once said that it is “easier to ask some of the questions than to come up with all the answers.” As a magazine editor, I get to ask lots of questions and make plenty of suggestions. Not everyone likes my suggestions, but I trust the readers of POWER to make their own studied […]
