<p>A waterbox for a shell and tube heat exchanger is disclosed. The waterbox is attached at one end of the heat exchanger to a tube sheet through which heat exchange tubes extend. Nozzle connections are made to the waterbox through a top member having an access opening which projects onto an area of the tube sheet through which the heat exchange tubes extend. The openings of the nozzles project onto areas on the tube sheet through which no heat exchange tubes extend. A removable cover is positioned over the access opening in the top member so that, when fluid flow conduits are connected to the nozzles on the top member, the conduits and removable cover are positioned relative to each other to allow removal of the cover without disturbing the connections between the conduits and the nozzles. In an alternative embodiment, the conduit connections are made through the back wall of the tube sheet rather than through the top member. This allows use of a waterbox with a removable top member having no nozzles.</p> |
