A measurement system using a Daniel Danalyzer gas chromatograph with controller and model 2522 flow computer is providing Tenaska significantly improved measurement of fuel/gas use and plant thermal efficiency. Tenaska owns and manages a Paris, Texas, generating station with two GE Frame 7EA gas turbines and a GE steam turbine in combined cycle. Gas consumption can approach 2,000 MBtu/h for the two turbines plus duct burners. Original equipment was based on orifice metering. Conversion from ther

An advanced pulverized coal combustion system with integrated emission controls and a net thermal efficiency of 42 percent is the goal of the U.S. Department of Energy`s (DOE) low-emission boiler system, or LEBS, program. Industry teams headed by three of the major boiler manufacturers are developing conceptual designs.

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
