摘要:
The exhaust gas of a turbine engine can include water vapor. Aspects of the invention relate to various systems for recovering water from the exhaust gas of a gas turbine engine. In one system, a portion of the exhaust gas can be routed to an absorption chiller. In another system, a portion of the exhaust gas can be routed to a direct contact heat exchanger. In a third system, a portion of the exhaust gas can be routed to a fin-fan cooler. In each of these systems, the portion of gas can be cooled below its dew point temperature to release a portion of its humidity as liquid water. Aspects of the invention can be used with the turbine exhaust of simple and combined cycle power plants. A water recovery system according to aspects of the invention can minimize or eliminate a power plant's dependence on local water sources.

Various embodiments implement agents as dynamically linked libraries to run within host processes controlled by an executable agent manager. The agent manager runs as a service or daemon continuously after being loaded into the memory of a computer system. Information concerning agents that are configured to carry out tasks on the computer system is stored in a database accessible to the agent manager. When a task that a particular agent is configured to carry out needs to be done, the agent manager assigns an executable host process to run the agent. The agent manager then sends start and stop commands to the host process to load and halt the agent, respectively.

A gas turbine combustion system for a turbine engine is disclosed. The gas turbine combustion system may include a plurality of combustor baskets positioned circumferentially about a longitudinal axis of the turbine engine, at least one firing nozzle extending into each of the plurality of combustor baskets and a fuel delivery system in communication with each of the at least one firing nozzles and in communication with at least one fuel source. Each combustor basket may include a fuel flow control device of the fuel delivery system inline with each of the at least one firing nozzles in that combustor basket such that fuel flow to some of the combustor baskets can be shut off while fuel flow to firing nozzles in other combustor baskets remains unobstructed, thereby permitting some combustor baskets to remain non-fired while other combustor baskets are firing to reduce CO emissions.

A turbine engine assembly for a generator including a turbine engine having a compressor section, a combustor section and a turbine section. An air bleed line is in communication with the combustor section for receiving combustor shell air from the combustor section and conveying the combustor shell air as bleed air to a plurality of stages of the turbine section. Bleed air is controlled to flow through the air bleed line when an operating load of the turbine engine assembly is less than a base load of the engine to bypass air exiting the compressor section around a combustor in the combustor section and effect a flow of high pressure combustor shell air to the stages of the turbine section.

A non-disruptive upgrade (NDU) technique involves installing and activating a first copy of a new version of an application in a temporary directory to (i) obtain control from an original version of the application while the original version is installed in an application directory and (ii) shut down the original version. The technique further involves, after the first copy of the new version obtains control from the original version and the original version is shut down, installing and activating a second copy of the new version of the application in the application directory to (i) obtain control from the first copy of the new version while the first copy of the new version is installed in the temporary directory and (ii) shut down the first copy of the new version. Such operation maintains the continuity of work at each phase of the NDU technique.

摘要:
A vehicle (10) includes a pair of hybrid track assemblies (12) mounted on opposite sides of the longitudinal axis (A) of the framework (11) of the vehicle (10) for cooperating to steer the vehicle (10). Each of the hybrid track assemblies (12) includes a first lead track (14) entrained about a first plurality of wheels (16) and a second lead track (18) entrained about a second plurality of wheels (20). A plurality of first lead rollers (26) are rotatably supported in spaced and parallel relationship to one another along the longitudinal axis of the first lead track (14). A plurality of second lead rollers (38) are rotatably supported in spaced and parallel relationship to one another along the longitudinal axis of the second lead track (18). The assembly is characterized by the first and second axes of the first lead rollers (26) and second lead rollers (38) being disposed in opposite directions, i.e., a herringbone configuration. By independent drive of each of the four tracks to provide various combinations of drive direction and speed for each respective track, the force vectors created by the rollers (26) and (38) engaging the surface add and subtract to effect movement in any direction.
