CoalTechno-Economic Considerations When Using Low-Grade Coal for Power Generation
The use of low-grade coal is becoming synonymous with circulating fluidized bed (CFB) power plants. Although CFB technology may often be a better choice than pulverized coal technology, that is not always the case. Owners and developers need to consider several technical and economic factors before making this decision.

Waste to EnergyExpanded Honolulu WTE Plant Delivers Triple Benefits for Oahu
Covanta Energy and the City and County of Honolulu recently completed a $300 million expansion of a 20-year-old waste-to-energy (WTE) facility. The plant is now capable of processing up to 3,000 tons of municipal refuse daily, recycling all the metals, and generating up to 90 MW—enough to supply nearly 10% of Oahu’s electricity.

Waste to EnergyWhy Aren’t Construction and Demolition Wastes Considered Biomass Fuel?
You may be surprised to learn that even with the increased demand for biomass fuels for power generation, construction and demolition fuel is classified as solid waste, not biomass. Reconsidering this designation is critical as U.S. environmental regulations tighten emission profiles for solid waste combustion units and renewable portfolio standards expand.

GasSelecting a Combined Cycle Water Chemistry Program
The lifeblood of the combined cycle plant is its water chemistry program. This is particularly true for plants designed for high pressures and temperatures as well as fast starts and cycling. Even though such plants are increasingly common, no universal chemistry program can be used for all of them.

WindRethinking Wind’s Impact on Emissions and Cycling Costs
Recent reports by the National Renewable Energy Laboratory and others suggest that the emissions-reducing benefits of renewable energy sources such as wind and solar may have been overstated and the cost of cycling fossil-fueled plants underestimated. These findings may change how utilities and policymakers weigh the costs and benefits of wind and solar energy.

NewsQuick-Release Mount for Fire Extinguishers
A new modular and durable quick-release mount for popular fire-extinguisher sizes is now available from Off-Road Solutions (ORS). The system uses two pieces of 6061-T6 billet aluminum: one attaches to the extinguisher while the other piece secures to a fixed object. The 3/16-inch hinge pin and 3/8-inch quick-release pull pin with detent ball are made […]

Nuclear
Too Dumb to Meter, Part 9
As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the 16th and 17th chapters, “Uranium Rush and the New ’49ers” and “Naked Shorts at Westinghouse,” the first two chapters of the “False Scarcity and Fools for Fuels” section.
