摘要： A lamp having a lighting source, integral electronics, and a thermal distribution mechanism disposed in a housing. The thermal distribution mechanism may include a variety of insulative, radiative, conductive, and convective heat distribution techniques. For example, the lamp may include a thermal shield between the lighting source and the integral electronics. The lamp also may have a forced convection mechanism, such as an air-moving device, disposed adjacent the integral electronics. A heat pipe, a heat sink, or another conductive heat transfer member also may be disposed in thermal communication with one or more of the integral electronics. For example, the integral electronics may be mounted to a thermally conductive board. The housing itself also may be thermally conductive to conductively spread the heat and convect/radiate the heat away from the lamp.

摘要： A method for assembling an exhaust hood for a turbine is provided. The method includes providing a bearing cone that substantially circumscribes a rotor of the turbine; and positioning a guide radially outward from the bearing cone. The guide and the bearing cone are configured to channel fluid from the turbine. The method also includes extending a guide cap from the guide. The guide cap is oriented to facilitate preventing the generation of fluid vortexes within the exhaust hood.

摘要： A heat recovery steam generator uses heat energy extracted from the exhaust gas of a gas turbine to produce steam. The steam is provided to steam turbines of a combined cycle power plant. Intermediate pressure steam generated by an intermediate pressure evaporator is routed to first and second intermediate pressure superheaters. Also, steam exhausted from a high pressure steam turbine of a combined cycle power plant is reheated by first and second reheaters within the heat recovery steam generator. The steam output by the intermediate pressure superheaters is provided to an interstage admission port of an intermediate pressure steam turbine, and steam output by the first and second reheaters is provided as the main input steam for the intermediate pressure steam turbine of the combined cycle power plant.

摘要： A steam turbine includes a diffuser that has a bearing cone and an inner plate of a steam guide that define a passage through which steam flows. An outer plate is disposed with respect to the inner plate such that an opening is located between the inner and outer plates. At least one hole is located in the inner plate. A water tube is disposed in the opening, the water tube having water flowing therethrough which condenses at least a portion of a flow of steam flowing in the passage thereby creating at least a partial vacuum within the opening. The vacuum creates a suction effect through the at least one hole in the inner plate that can cause at least a portion of the flow of steam in the passage to attach itself to an inner surface of the inner plate.

摘要： Disclosed herein is a method of minimizing losses in a multiple-last-stage bucket turbine. The method includes, determining an inlet flow available for the multiple-last-stage bucket turbine, and selecting multiple last-stage buckets from a set of pre-designed last-stage buckets. The multiple last-stage buckets having inlet flows different from one another that when combined match the inlet flow available with a lower total exhaust loss than from multiple same sized last-stage buckets from the set of pre-designed last-stage buckets.
