摘要： A loose parts collection weir that is a nearly cylindrical structure that is integrally attached to the lower deck plate or sludge collector top plate of a steam generator to retain loose parts along the feedwater and recirculation water transit path to the tube bundle. The weir is a near vertical structure built into the upper drum of the steam generator, near the periphery of the lower deck plate or sludge collector top plate in the vicinity of the downcomer annulus. The weir may contain a radially inwardly projecting lip which forms a pocket for loose parts to collect. As the feedwater flows toward the downcomer annulus, loose parts will tend to deposit onto the lower deck plate aided by gravity and be trapped by the loose parts collection weir.
摘要翻译： 一种松散的部件收集堰，其是几乎圆柱形的结构，其整体地附接到蒸汽发生器的下甲板板或污泥收集器顶板，以沿着给水和沿管道的再循环水输送路径保持松散的部件。 堰是内置于蒸汽发生器的上滚筒中的近垂直结构，靠近下层甲板的周边或降液管环的附近的污泥收集器顶板。 堰可包含径向向内突出的唇缘，其形成用于松散部件收集的口袋。 随着给水流向降液管环，松散的部件将倾向于通过重力沉积到下甲板板上，并被松散的部件收集堰捕获。

摘要： A means of offsetting semi-circular tube support plates typically present in heat exchangers with cross flow baffles, such as axial flow economizers, utilizing the motive force of steam generator pressurization. The offset slightly flexes the tubes, thereby providing a preload which minimizes the potential for tube vibration and wear.

摘要： This invention relates to an in-situ cleaning fixture for demister separator vane assemblies. The cleaning fixture includes an injection chamber with an inlet and a perforated plate which extends horizontally, substantially over the length of the demister separator vane assembly. A cleaning fluid source is connected to the injection chamber during a cleaning process. The injection chamber is designed to receive the cleaning fluid, pass the cleaning fluid through the holes formed in the plate, downwardly along a plurality of vanes in the demister separator vane assembly and into the drain trough. The in-situ cleaning fixture facilitates removal of scale build-up from the demister separator vane assembly and thereby restores the efficacy of the vanes.
