Abstract:
A combined steam condenser and heat exchanger comprising:an outer steam condenser shell having a large diameter opening to receive steam and a small diameter steam condensate outlet;an inner heat exchanger shell supported within the outer steam condenser shell and separated from the outer steam condenser shell to provide a space between the inner heat exchanger shell and the outer steam condenser shell surrounding the inner heat exchanger shell;a first plurality of tubes extending through the inner heat exchanger shell;a second plurality of tubes extending through the space between the inner heat exchanger shell and the outer steam condenser shell;at least two tube support members for supporting both pluralities of tubes within the inner heat exchanger shell and in the space between the inner heat exchanger shell and the outer steam condenser shell, respectively;an inlet head at one end of the outer steam condenser shell having a cooling liquid inlet for supplying cooling liquid to the tubes;a cooling liquid outlet for conveying cooling liquid from the combined condenser and heat exchanger after it has passed through both pluralities of tubes;a heat exchanger inlet for supplying a liquid to be cooled to a space between the first plurality of tubes within the inner heat exchanger shell in heat exchange relation to the cooling liquid in the tubes; anda heat exchanger outlet having approximately the same equivalent hydraulic diameter as the heat exchanger inlet for removing cooled liquid from the space between the first plurality of tubes within the inner heat exchanger shell.
