Abstract

A vapor condenser includes a conduit defining a passage for guidingly communicating a vapor stream in a vapor flow direction from an inlet at a first location to a second location, a first heat exchanger between the first and second locations for open heat exchange between the vapor and a first coolant, the first coolant flowing in a direction that is counter to the vapor flow direction, and a second heat exchanger between the first and second locations for open heat exchange between the vapor and a second coolant. The vapor condenser automatically controls the flow rate of coolant in the first heat exchanger in response to changes in the density of the vapor in the vapor stream entering the conduit. Control of the flow rate of coolant is maintained, for example, by controlling the flow rate of individual dispersal devices, such as nozzles, or by controlling the number of nozzles operating.
