TOP PLANT: Tosunlar 1 Akca Plant, Saraykoy, Denizli, Turkey
Owner/operator: Akca Enerji Geothermal energy has long been handicapped by its need for high-temperature resources to generate economic power, but innovations in binary Organic Rankine Cycle systems are making it possible to exploit low-temperature sites. An innovative plant in Turkey using Italian technology has taken things a step further with a unique two-pressure, multistage, single-disk […]

“Who Moved My Btus?” The Pitfalls of Extended Coal Storage
Many coal power stations have recently been operating at historically low capacity factors or have even undergone extended economic shutdowns. This can result in coal stockpiles that are exposed to the elements for much longer times than anticipated, resulting in a loss of usable coal energy by several mechanisms. This article explores the severity of […]

Advanced Furnace Draft Pressure Control Using Electraulic Damper Drives
Pneumatic furnace damper drives may be more common, but electro-hydraulic actuators provide several advantages to the more traditional control scheme. One fossil-fired plant in Taiwan achieved more consistent and accurate furnace draft pressure control by retrofitting its dampers with Electraulic actuators, optimizing combustion and increasing boiler availability in the process. Fossil fuel–fired power plants worldwide […]

Ontario Power Generation: A Clash of Politics and Power Planning
Ontario—Canada’s most populous province and its major economic engine—has an electric power supply system so driven by provincial politics that it has pushed the province’s utility generating arm, Ontario Power Generation, into what appear to be incoherent resource policies. Late last September, in a stunning announcement, the Canadian province of Ontario’s Energy Ministry said it […]
