ABB Power Generation?s GT24 and GT26 advanced gas turbines produced single-digit NOx emissions during combustion testing. These are the first two models of ABB?s advanced gas turbine family to utilize a sequential combustion system consisting of two annular combustors, an EV and an SEV. These test results dispel an industry myth that high thermal efficiency is incompatible with low emissions.

Anyone watching the gas turbine industry already knows that advancements in efficiency, output and emissions control are coming fast and furious. Federal, state and local regulations, the spotty demand for power, low capital requirements and fast construction cycles all have their effect on the demand for gas turbines. Manufacturers competing for sales realize that to maintain a viable presence in the market they must accelerate the product cycle and introduce new designs and technological innov

The Institute of Clean Air Cos. (ICAC), the national association of stationary source air pollution control companies, has released a revised version of its white paper, Selective Catalytic Reduction (SCR) Controls to Abate NOx Emissions. The paper, written by ICAC?s SCR Committee, provides information on the capabilities, limitations, applications and costs of SCR.

Dale Simbeck, vice president of technology, SFA Pacific, Inc., Mountain View, Calif., speaking at the recent Council of Industrial Boiler Owners` fluidized bed conference in Jacksonville, Fla., said that fluidized bed combustion (FBC) technology has now become a major competitor for conventional solid fuel combustion systems worldwide. Here in the United States independent power producers and cogenerators have led the way in deploying FBC boilers for electric power generation. Utility type rehea

Members of a North Carolina church will move into their expanded church facility sooner than expected. An arrangement to provide much needed low cost landfill material made the project possible thanks to a cooperative effort of the New Covenant United Methodist Church?s building committee, Duke Power Co., and contractor Trans-Ash of Cincinnati, Ohio.

The least-cost producers of electricity in the United States over the five-year period 1989 to 1993 are coal-fired power plants west of the Mississippi River burning low-sulfur coal. These data are confirmed in a recent analysis of production expenses for 707 power plants producing 85 percent of U.S. electric utility output by the Utility Data Institute (UDI).
