When injuries or accidents occur, the employer ultimately loses on two counts: increased medical costs and employee absences. A policy of "safety, compliance, and then production" is more than just good business; it’s also good stewardship of the health and safety of employees who deserve no less.

Keeping coal-fired steam plants running efficiently and cleanly is a daily struggle. An article in the February 2007 issue of POWER explained that one way to improve the combustion and emissions performance of a plant is to optimize the performance of its coal pulverizers. By adding a dynamic classifier to the pulverizers, you can better control coal particle sizing and fineness—and increase pulverizer capacity to boot.

The latest benchmarking study by the EUCG examines the technology and costs of 49 flue gas desulfurization systems currently under design or construction by 12 of the nation’s largest utilities. Although the study’s detailed results are proprietary to EUCG members that participated in it, POWER was given access to the top-level findings. To get details at the plant/unit level, you’ll have to join the EUCG and participate in the study, which is ongoing.

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 […]
