    摘要： A vapor generator in which a plurality of tubes are connected together and arranged to form at least a portion of the boundary walls of a gas-tight enclosure. Portions of the tubes are bent to form a plurality of openings extending through at least one of the boundary walls. Some of the bent tube portions extend around the openings in the plane of the wall, and others of the bent tube portions extend out of the plane of the wall. The tubes, including the bent portions, extend at an angle with respect to a horizontal plane for their entire lengths to enable the tubes to drain. A burner is associated with each opening to apply heat to the enclosure, and fluid is passed through the tubes to apply heat to the fluid.

    摘要： The vapor generator is provided with a vapor separator which is connected to an outlet of the partition and which has a water outlet connected to the inlet of the enclosing walls of the combustion chambers. The vapor outlet of the vapor separator connects to a superheater within the generator via platen superheaters disposed within their respective combustion chambers. The vapor separator permits the partition to always be operated with a considerable surplus of water so that no stability problems occur. A water separator is also connected to an outlet of the enclosing walls and has a vapor outlet connected with the vapor outlet from the vapor separator. Various control circuits can be used to regulate the flow of vapor from the vapor separator to the superheater. A branch conduit for the feed water is also connected in parallel with the partition to permit mixing of some of the feed water with the water separated out of the vapor separator prior to passage into the enclosing walls of the generator.

    摘要翻译： 蒸汽发生器设置有蒸气分离器，蒸气分离器连接到分隔件的出口，并且具有连接到燃烧室的封闭壁的入口的出水口。 蒸汽分离器的蒸汽出口通过设置在它们各自的燃烧室内的压板过热器连接到发电机内的过热器。 蒸汽分离器允许隔板总是以相当多的水运行，从而不会发生稳定性问题。 水分离器也连接到封闭壁的出口，并具有与蒸汽分离器的蒸汽出口连接的蒸气出口。 可以使用各种控制电路来调节从蒸气分离器到过热器的蒸气流。 用于给水的分支管道也与隔板并联连接，以便在进入发生器的封闭壁之前将一些给水与从蒸汽分离器分离的水混合。

    摘要： A once-through vapor generator in which the roof and heat recovery area rear wall comprise a single continuous downflow pass feeding the generator primary superheater. An outlet header for the pass, at the lower end of the pass, also serves as the inlet header for the primary superheater, flow from the header being upwardly in the superheater. A plurality of diaphragms at spaced intervals along the axis of this common header divide the header into a plurality of separate sections which in turn form in the downflow pass and superheater a plurality of narrow-width parallel down-up flow circuits. The invention prevents the occurrence of recirculation of flow at low loads within the roof and heat recovery area rear wall. A plurality of mix headers may be employed in each down-up flow circuit, at a midpoint in elevation in the heat recovery area rear wall. This reduces the possibility of recirculation within a particular down-up flow circuit in large sized units having a large difference in elevation between the roof inlet header and the lower common header.
