Abstract: A method and system to extract gas from a gas turbine having at least one gas extraction mechanism placed at the turbine section that extracts exhaust gas directly from the turbine stages through the turbine casing, providing a first exhaust gas path that extends from the turbine section through the exhaust section to the exhaust gas outlet, and a second exhaust gas path for extracted exhaust gas extending directly from the turbine stages inside the turbine casing to a duct outside of the turbine casing. The gas extraction system and method can be applied to a cogeneration system.

Abstract: A method of determining the moment weight of a rotating component for a rotary machine includes the steps of: (a) supporting the component on a platform at a pair of spaced locations along a length dimension of the component, one of the spaced locations corresponding to a known radial distance from a centerline of a rotor of the rotary machine to a predetermined location on the component when the component is installed on the rotary machine, and wherein a center of gravity of the component is located between the spaced locations; (b) determining partial weights of the rotary machine component by supporting the platform on a pair of weight scales vertically aligned with and substantially centered on the spaced locations, wherein a total weight TW of the component is equal to a sum of the partial weights; (c) utilizing information obtained in step (b), locating a center of gravity of the component relative to the one of the spaced locations and determining a radial distance D1 between the center of gravity and
