EPRI Journal archives from July 1994

Trying to take the nitrogen out of coal.
July 1, 1994... Scientists believe that at the molecular level the nitrogen content of coal is bound up in hexagonal chemical structures similar to those in a honeycomb. Such structures are extremely strong, making the nitrogen difficult to remove. By...

Ultrasound technique could help utility boilers.
July 1, 1994... Most widely known for its use in monitoring fetal development, ultrasound technology is also employed in a variety of other applications, from detecting bubbles in blood transfusions to tracking yeast particles in the beer-making process. Now...

Worldwide activity in IGCC. (integrated gasification-combined-cycle technology)(includes related article) (Cover Story)
July 1, 1994... A decade after the world's cleanest coal-fired power plant generated its first kilowatt of electricity in the southern California desert, the technology employed there is beginning to catch on. Buoyed largely by the wave of environmental...

The energy-efficient office. (Office Technology Efficency Consortium)
July 1, 1994... Electronic office equipment represents the fastest-growing electrical load in the fastest-growing utility market segment. As personal computers, printers, copiers, and fax machines have proliferated throughout the commercial sector, they have...

Storing megawatthours with SMES. (superconducting magnetic energy storage)
July 1, 1994... Laboratories around the world continue to make significant strides in developing electric power applications for recently discovered high-temperature superconducting materials--materials that lose electrical resistance when cooled to the...

Micro-SMES powers critical customer processes. (superconducting magnetic energy storage)
July 1, 1994... Electric utilities view superconducting magnetic energy storage (SMES) and other forms of energy storage as a highly flexible type of generating capacity that can also provide a suite of quantifiable dynamic operating benefits. But at the...

Understanding the global carbon cycle.
July 1, 1994... One of the most important uncertainties in the debate over the potential for climate change due to rising emissions of greenhouse gases is the question of how fast these gases will actually accumulate in the atmosphere over the next 50-100...

Toledo Edison validates demineralizer operation at high temperatures.
July 1, 1994... In pressurized water reactors with once-through steam generators, moisture separator drains have a higher concentration of corrosive ions like sodium, chloride, and sulfate than do most other points in the secondary coolant loop. The higher...

EPRI sees big potential in electroseparation. (Electric Power Research Institute)
July 1, 1994... Not long ago, the best means available for cleaning up a site contaminated by metal spills was simply to excavate the dirty soil--a labor-intensive and costly task. But researchers in the United States and Europe are developing a more efficient...

Developing mercury removal methods for power plants.
July 1, 1994... Trace substance emissions in utility power plant flue gas have increased in importance since the passage of the Clean Air Act Amendments (CAAA) of 1990, which mandate the Environmental Protection Agency to conduct a three-year study of public...

USABC jump-starts EV battery development. (US Advanced Battery Consortium; electric vehicles)
July 1, 1994... Faced with severe air quality problems, California adopted regulations in 1990 that may revolutionize the automotive world. The California rules require that 2% of the automobiles and light-duty trucks produced for sale in the state in 1998 be...
