Thanks to using local coal, it will pay dividends to the municipal utilitys customers for years to come in the form of low rates supported by income from the sale of surplus power to the wholesale market. As one of the cleanest coal-fired plants in the U.S., the plant makes environmental sense, too. SPECIAL REPORTS 2009 MARMADUKE AWARD38 The Hague Repowering Project Upgrades CHP System, Preserves Historic BuildingThis years winner of the Marmaduke Award for excellence in O&M goes to a project that pulled off something much harder than a facelift. The challenge was to preserve the century-old historic exterior of The Hague Power Station while replacing its ag-ing heart with high-efficiency turbines to ensure that the plant will provide heat and power to the Dutch city for many years to come. SOLID WASTE MANAGEMENT46 Improved FGD Dewatering Process Cuts Solid WasteHow would you like to save over half a million dollars in costs related to flue gas de-sulfurization solids? The plant in this case study shows you how it did just that. (Can you really afford not to read this?) GENERATION TECHNOLOGY52 IGCC Update: Are We There Yet?Integrated gasification combined cycle has for many years been a promising tech-nology. Three experts weigh in on the current balance of pros and cons, and on when IGCC is likely to deliver on its promises. FEATURES CARBON MANAGEMENT58 Commercially Available CO2 Capture TechnologyFluor Corp.s Econamine FG Plus (EFG+) technology has been widely used in the gas-treating industry for two decades. Here the company makes the case for using EFG+ in coal-fired power plants by explaining how the process works and sharing its oper-ating experience with the process at a gas-fired power plant. 28CIRCLE 4 ON READER SERVICE CARD TK www.powermag.com POWER |August 2009 2 STEAM TURBINES62 Preventing Turbine Water Damage: TDP-1 UpdatedThe latest revision of ASMEs Recommended Practices for the Prevention of Water Damage to Steam Turbines Used for Electric Power Generation: Fossil-Fuel Plants in-cludes recommendations that apply to the newest power plant technologies, includ-ing combined cycles and digital controls. Consider its design and operating advice an ounce of prevention. COMBUSTION SYSTEM DESIGN66 Flexible Fuel Combustor Design Accommodates LNG Variations in the constituent elements of liquefied natural gas (LNG) can adversely affect the operation of power generation turbines using the fuel. Siemens explains how it is developing an LNG-capable turbine, and modifications for currently avail-able turbines, to handle the fuel variations that are likely to affect increasing num-bers of plants. CLASSIC MARMADUKE71 Marmys Deep-Freeze BlackoutEach year, as a companion to our report on the Marmaduke Award winner, we reprint a story about the fictional plant troubleshooter Marmaduke Surfaceblow. This year we dusted off a tale based on a true scenario set in Greenland.
