The EPA does no t report emission of Sulfr hexafluoride separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sf 6. The emissions of HFCs, PFCs, and sf6 gas for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.

Microturbine Technology Matures - POWER Magazine

Typical Microturbine ConstructionRecent Case StudiesIntegrating Solar EnergyMicroturbines are a simple form of gas turbine, usually featuring a radial compressor and turbine rotors and often using just one stage of each. They typically recover exhaust energy to preheat compressed inlet air, thereby increasing electrical efficiency compared with a simple-cycle machine. The air-to-air heat exchanger is termed a “recuperator,” and the entire system is typically called a recuperated cycle. Figure 2 shows a cutaway view of a Capstone 65-kW microturbine illustrating how these major components are arranged in a commercial product. The assembly is often called a “turbogenerator,” as it includes all the microturbine components plus the generator. The single shaft of turbine, compressor, and generator rotates at high speed—96,000 rpm in the case of the Capstone C65 turbogenerator. Generator output is therefore high-frequency AC, which must be conditioned using power electronics to provide a useable 50 or 60 Hertz electrical output. Microturbines provide high electric...
