Tuning power plant controls takes nerves of steel and an intimate knowledge of plant systems gained only by experience. Tuning controls also requires equal parts art and science, which probably is why there are so few tuning experts in the power industry. In Part I of a two-part series, we explore a mix of the theoretical and practical aspects of tuning boiler controls.

The Estick electronic contact temperature indicator provides an instantaneous digital readout of surface temperature at the point of contact with an accuracy of ±1%. Knowledge of the material’s emissivity is not required to get an accurate reading, says the device’s maker, TEMPIL, and it can gauge temperatures of ridged, polished, or nonpolished surfaces. The Estik’s […]

Pulverizer throughput is determined by the coal fineness desired for a given coal. However, compromising on coal fineness when your pulverizer isn’t up to snuff can increase NO _x and cause many furnace problems. Your least costly option for increasing pulverizer capacity is to pay careful attention to key dimensions and critical tolerances during your next overhaul.

As the Obama administration takes office, energy resource allocation is both the most critical national security issue and the most critical economic issue facing us. It will be difficult to sustain and improve economic growth unless we implement policies that result in the more rational use of energy resources, especially those for which there is a finite supply.

Just after midnight on Dec. 22, 2008, a 40-acre pond holding coal combustion waste for a Tennessee Valley Authority (TVA) steam power plant ruptured, sending a wave of wet ash across 300 acres of rural land in Harriman County, Tenn. It was the largest coal slurry spill in U.S. history — more than three times the size of the Martin Country, Ky., sludge spill of 2000, and about eight times that of the 1972 Buffalo Creek flood in West Virginia. Unlike that flood, which killed 125 people and injured scores others, this one, Tennessee authorities reported, resulted in no serious injuries or hospitalizations.

A year after Exelon Nuclear ceremoniously announced the selection of General Electric-Hitachi’s Economic & Simplified Boiling Water Reactor (ESBWR) design (Figure 2) as its preferred technology for a proposed two-unit nuclear facility in Victoria County, Texas, the operator of the largest nuclear power fleet in the U.S. — and the third-largest in the world — said it had reconsidered its decision. The company said it is now negotiating separately with Toshiba and GE-Hitachi, both vendors of the Advanced Boiling Water Reactor (ABWR), and with Mitsubishi Heavy Industries for its U.S. Advanced Pressurized Water Reactor (US APWR).

I just renewed my professional society membership dues for the umpteenth year, and while writing the check, I paused to consider if I was getting good value from them. I expect to receive another "suitable for framing" certificate this year, as the number of my membership years ends with a zero, but I wondered if there were other, more tangible benefits.

China has put its nuclear power plans on a fast track, kicking off a construction frenzy worth billions of dollars. In the latter months of 2008, the nation inaugurated construction of seven reactors, and in 2009, work will begin on another 10.

Despite hostilities that linger as a result of the 1986 nuclear nightmare at Chernobyl, Ukraine, and pressure from the European Union to shut down older-generation plants, Eastern European countries from the Baltic to Bulgaria are renovating existing nuclear plants or building new ones. If these projects become reality, the region will be able to secure its power supplies as well as cover the ongoing shortages in countries such as Greece, Macedonia, and Albania.

A confluence of circumstances promised to make 2008 a transformative year for renewable energy in the U.S. States enacted additional, and more demanding, renewable portfolio standards, promoting accelerated and sustained development of "green" energy resources. Increasing concerns about global warming and climate change prompted some of this activity. However, the unprecedented escalation of oil prices to almost $150 a barrel (translating into prices at the pump in excess of $4) was the largest impetus for demands that this nation end its addiction to fossil fuels.

Declining oil prices, supply issues, and dwindling financing may have battered solar energy in recent months, but the industry seems to have sparred well in the research arena.
