摘要： An air-cooled steam condensing module with an integral vent condenser has a steam header, one or more rows of condensing tubes between the steam header and a (generally lower) common condensate header. The module also has at least one row of vent condenser or dephlegmator tubes located adjacent the condensing tubes which connect the lower header to a vent header. The dephlegmator tubes may be of the same or larger diameter than the condensing tubes.

摘要： A two-stage steam condenser that prevents freezing from occurring in the tube rows by continual purging of the tube rows. Such continual purging prevents any steam from back-flowing into a tube row thereby eliminating the possibility that condensate or noncondensable gases will become trapped therein. This is achieved by isolating each of the tube rows in the second stage of the condenser so that the pressure of one tube row is not exposed to the pressure occurring in another adjacent tube row. The condensate collected in the various tube rows of this second stage is delivered to a common drain pot that is hydraulically balanced to accommodate the various pressures in these tube rows. Such hydraulic balancing also prevents any back-flowing from occurring from one tube row into another. Furthermore, in this second stage of the steam condenser, the steam and resulting condensate both flow concurrently downward while any noncondensable gases are vented counter-currently upward against such steam and condensate flow.
摘要翻译： 两级蒸汽冷凝器，通过连续吹扫管排，防止管排中发生冻结。 这种持续吹扫防止任何蒸汽回流到管排中，从而消除了冷凝物或不可冷凝气体将被捕获在其中的可能性。 这通过隔离冷凝器的第二级中的每个管排来实现，使得一个管排的压力不暴露于在另一相邻管排中发生的压力。 收集在该第二阶段的各管排中的冷凝物被输送到液压平衡以容纳这些管排中的各种压力的公共排水罐。 这种液压平衡还防止从一个管排发生到另一个管排的任何反向流动。 此外，在蒸汽冷凝器的第二阶段中，蒸汽和产生的冷凝物两者同时向下流动，而任何不可冷凝气体相对于这种蒸汽和冷凝物流反向排出。

摘要： A device for using the density control water to continuously flush the oxidation air header and the sparge pipes in a flue gas wet scrubber agitation tank. The density control line is routed to the elevation where the control valve is located. A U-shaped trap is located between the control valve and air sparge header such that the density control water joins the humidified oxidation air. A liquid layer forms on the floor of the header and is moved toward the distant side of the header by the motion of the air passing on top of the liquid layer and by the continuous flow of water. The bottom section of the main header is perforated to allow the flowing water to exit the header into the tank and flush any accumulated solids that might penetrate the header through the air holes. The air holes are located in a section at a minimum of five degrees off the floor and maximum of one hundred eighty degrees off the header bottom and preferably at forty-five degrees. The distant end of the header has an opening located close to the header floor to provide an outlet for the flushed solids and prevents the formation of back waves in the header.

摘要： An air sparger assembly for a flue gas desulfurization wet scrubber agitation tank that eliminates the need for a mixer and reduces the amount of piping required. The air sparge pipes are arranged to be concentric with the agitation tank. A single main header provides air to the air sparge pipes. The discrete location of the air discharge holes in the sparge pipes utilizes the buoyant energy of the oxidation air to mix the slurry in the agitation tank.
