    摘要: An apparatus in a steam generator that employs tube support plates within a shroud that is in turn disposed within a shell. The tube support plates are made of a material having a coefficient of thermal expansion lower than that of the shroud. The tube support plates are aligned during fabrication with minimal clearances between components. Using a tube support displacement system, a controlled misalignment is imposed on one or more tube support plates as the steam generator heats up. The tube support plate displacement system has only two parts, a spring bar and a push rod, that are internal to the steam generator shell and threadably engaged, thereby minimizing the potential of loose parts. The tube support plate displacement system can be used to provide controlled misalignments on one or more tube support plates, with one or more apparatus being provided for any individual tube support plate.

    摘要: A cooling system integrating a plurality of evaporative chillers, which each cool water to below ambient wet bulb temperature. In an air-to-air heat exchanger of each chiller, the incoming airstream used to evaporate water from the water stream is first cooled indirectly using the cooled air that is exhausted from a saturator of an adjacent chiller or subunit. By pre-chilling the air without adding moisture, each of the chillers of the cooling system is able to achieve water temperatures below the ambient wet bulb temperature. The system integrates or “daisy chains” multiple sub-wet bulb evaporative chillers or subunits such that the cool air output from one subunit is used to pre-cool the incoming air of another neighboring unit. To this end, adjacent units have their heat exchangers fluidically connected together (e.g., air flow output from each saturator is passed as cool return air through channels of an adjacent heat exchanger).
