The system for condensing gases such as steam includes a housing with a gas inlet. At least one vertical column of vertically spaced separate tube bundles are in the housing. A separate water conduit is connected to the inlet of each of the separate tube bundles.

An improvement on the end plate shear connection (Table IX, Section 4-57, Seventh Edition A I S C Manual of Steel Construction) in which the end plate has an integral stem plate at right angles to the end plate and offset from the center line of the end plate to compensate for the web thickness of the beam to which the end plate is to be connected. The end plate is secured to the web of the beam by a shop weld with the weld adjacent the end plate fully penetrating the web, the stem plate and the end plate. Before welding, the stem plate is clamped to the web and minor adjustments made so that when welded the finished length of the beam will be proper and the end plate will be properly located and aligned with the center line of the beam. The end plate - stem plate unit is prefabricated in stock sizes. The unit may be a rolled shape. The stem plate may be joined to the end plate by a single fillet weld at the junction between the stem plate and the end plate remote from the web. The stem plate serves as a back-up bar while making a full penetration weld between the end plate and the web, from one side only of the beam.

The arrangement includes a plurality of vertical water pipes with nozzles arranged on the pipes in a manner to minimize interaction between the water droplets coming from the nozzles. The arrangement consists of a plurality of spaced vertical water pipes arranged about a central area with a plurality of vertically spaced water nozzles located on each pipe. The nozzles on each vertical pipe are located along different horizontal planes from the nozzles on the adjacent vertical pipes. In another arrangement the vertically spaced nozzles on each vertical water pipe are circumferentially spaced from each vertically adjacent nozzle. Groups of vertical water pipes may be concentrically arranged about the central area with the spacing between the groups, the spacing of the vertical water pipes in each group and the location of the nozzles minimizing the interaction of the water droplets from the nozzles.
