摘要： A locomotive control system for performance assessment of a locomotive engine includes a controller and at least one sensor coupled to the controller. The at least one sensor is located proximal to the locomotive engine so as to gather actual performance data from the locomotive engine. The controller monitors locomotive current operating conditions and utilizes the current operating conditions to calculate predicted performance. The controller compares the predicted performance output based upon the current operating conditions with the actual performance data to monitor any substantial deviations therefrom.

摘要： In a gas turbine having a compressor discharge casing, a cooling circuit diverts compressor discharge air toward a high pressure packing (HPP) circuit. The cooling circuit includes an inlet pipe that receives compressor discharge air. One or several cooled cooling air pipes are in fluid communication with the inlet pipe via a pipe manifold, which distributes the discharge air across the cooled cooling air pipes. A seal is disposed upstream of an entrance to the HPP circuit to limit flow into the HPP circuit, and a second seal is disposed downstream of the HPP circuit at turbine wheelspace to limit ingestion and thus the purge flow air required. The circuit serves to reduce required purge flow in the HPP circuit so that an amount of compressor discharge air can be put back to the main flow path, thereby improving turbine performance.

摘要： In a steam turbine high pressure end seal region, brush seals are provided between first and second pressure regions having a pressure drop in excess of the sealing capacity of an individual brush seal. To use brush seals between the first and second regions, one or more intermediate pressure regions are maintained at a substantially fixed predetermined pressure between the first and second pressure regions. Brush seals are interposed between adjacent pressure regions whereby the pressure drop between adjacent pressure regions is within the sealing capacity of the individual brush seal disposed between the adjacent pressure regions.

摘要： In a steam turbine, a combined brush and labyrinth seal is provided between a diaphragm web and a radially outwardly projecting platform between axially adjacent wheels on the rotor. The brush seal is located upstream of the labyrinth seal teeth. The platform has at least one and preferably a pair of flanges or fins projecting in opposite axial directions adjacent radial outer ends of the platform. Non-uniform heat distribution resulting from the frictional contact between the bristles of the brush seal and a sealing surface on the platform along the rotor surface affecting rotor dynamics is thereby eliminated or minimized.
