Sampling of steam and condensate at electric utilities is common practice, and indeed, virtually all utilities sample some points in the steam/water circuit. However, the sampling methods are often far from ideal. Poorly collected or conditioned samples can be almost as bad as no samples at all because they give a false indication of unit conditions.
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
Thermal barrier coatings (TBC) have become a standard tool among engineers and designers looking to extend gas turbine component life. Air-plasma sprayed (APS) yttria-stabilized zirconia TBCs have become the predominant technology, but in spite of a solid and reliable history, the material and the way it is applied continues to be studied and refined. In a paper presented at the June 1995 International Gas Turbine and Aeroengine Congress and Exposition, GE engineers Warren A. Nelson, Robert M. O
You are fairly close to the solution when you state that the mandatory purchase requirement mandated by PURPA should be repealed. What should be repealed is the "so-called" avoided cost.
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.
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,
