When O`Brien California Cogen Ltd. was contracted to develop a system to generate steam for an Artesia, Calif., milk producer`s evaporation process, local regulations required NOx emissions reduced to 9 ppm and CO to 10 ppm. Johnson Matthey supplied the solution with a custom system combining an oxidation catalyst to control CO emissions and a selective catalytic reduction (SCR) system to control NOx. O`Brien`s cogen operation runs off an aircraft-derivative GE Gas Turbine, model LM2500, with a
The 150,000+ square foot Richmond facility serves as ABB Power Generation Inc.`s major manufacturing, assembly, test, service and repair facility in the United States. As part of a global operation, Richmond draws on ABB`s worldwide engineering expertise and broad technology base.
Reading like a who`s who of the power industry, the members of the Collaborative Advanced Gas Turbine (CAGT) program have been putting their minds as well as their pocketbooks behind an effort to commercialize an advanced form of gas turbine technology. The ultimate goal of the CAGT program, said Ralph Hollenbacher from Energy Options and Arthur Cohn, Electric Power Research Institute, is that through close cooperation and collaboration, the community of stakeholders in the growing market for na
With pressure to pull more life and better performance from aging plants, utilities are turning more and more to protective coating of turbine internals. Such coating has saved electric utilities, airlines and the military tens of billions of dollars annually in fuel, replacement parts and repairs.
If only Brayton and Rankine could see how well their children are getting along. A marriage made in heaven, the synergy the combination of the Brayton and Rankine cycles bring to power generation is a whole that is certainly greater than the sum of its parts. The gas turbine combined cycle has become a very popular plant concept in the past 10 to 15 years and for obvious reasons. Efficient, clean and less costly to construct then most alternatives, combined-cycle plants offer a blend of operatio
Gas turbine technology is swiftly evolving as manufacturers introduce aero-derived advances in the pursuit of more power
Combining the best features of simple- and combined-cycle gas turbine power plants, the CHAT cycle concept offers power producers a clean, more efficient and less expensive alternative to both
Good things really do come in small packages. Starting with a notion on how to develop cogeneration projects more efficiently, a new mobile cogeneration unit (MCU) manufactured by AGC Manufacturing Services Inc., a member company of the Affiliated Group of Cos. (AGC) in Tulsa, Okla., offers industrial power users a unique set of options when it comes to managing energy needs. Designed to supply power to small to mid-sized industrial plants that might not otherwise consider on-site cogeneration,
Florida Power & Light Co.?s (FP&L) St. Lucie power plant, a two-unit, 1,700-MW nuclear electric generating facility, selected Applied Radiological Control Inc. (ARC) for its turbine component cleaning project in preparation for non-destructive examination. The decision was made after extensive evaluation of cleaning principles and methods, non-destructive examination of metal substrates and a full-scale demonstration of ARC?s ultra high pressure (UHP) water-jetting process.
Ironically, the role of the piston in power production seems to be expanding. The irony lies in the fact that technology developed at the turn of the last century is poised to take on an even greater portion of electric power generation at the turn of this century, despite advances in other, more contemporary prime movers such as gas turbines.
