    Abstract: A preheater or economizer section is provided in a shell-andtube vapor generator. The preheater section is baffled to conduct incoming feedwater along a flow path within which it will be heated to an elevated temperature before contacting parts of the vapor generator unit that would be susceptible to thermal stresses.

    Abstract: Feedwater preheating apparatus for a shell and tube type vapor generator is disclosed incorporating a plurality of nozzles arranged to discharge cold feedwater into a collector conduit disposed in a region of the unit containing heated fluid. Inductor means are provided to aspirate heated fluid into the collector conduit for mixing with the feedwater whereby the latter is heated.

    Abstract: Antivibration tube spacer structure for supportingly spacing adjacent tubes of a shell and tube heat exchanger in order to prevent damage to the tubes caused by flow-induced or other mechanically induced vibration. The spacer structure comprises elongated, thin plate members disposed between adjacent tube layers thus to provide engagement at two opposed points on the tubes. Struck out tab projections extending normally from the plate are arranged to engage the tubes on opposite, longitudinally-spaced points that are displaced by 90* from the points of plate engagement.

    Abstract: A shell and tube type vapor generator is disclosed in which the vaporizable liquid supply to the evaporator region of the apparatus is automatically regulated in response to load changes on the unit. The vapor generator incorporates a plurality of conduits arranged to conduct liquid from the downcomer reservoir to the evaporation region. The conduits are arranged in such a way that the number of conduits conducting liquid from the reservoir to the evaporator is variable according to the load demand on the unit.
