Abstract
A rectifier column for a vapor generator means of a heat transfer system having a reflux inlet and modulating means at said inlet responsive to a condition representative of the quality of the vapor being generated so as to control the flow of reflux into the column thereby maintaining optimum vapor generation. In one arrangement the modulating means comprises a temperature sensitive actuator, e.g. a wax filled bellows which is situated in the path of the generated vapor at the output of the column.
Claims16
A vapor rectifier column comprising a vapor output, a vapor reflux inlet coupled to a reflux source, modulating means disposed at said inlet for controlling the flow of reflux into said column, and temperature sensitive means located at an upper portion of said column, wherein said temperature sensitive means is responsive to the temperature of vapor occurring at said upper portion of said column, and said modulating means is actuated by said temperature sensitive means to maintain said vapor at an optimum concentration
A heat transfer apparatus comprising a closed fluid circulatory system comprising vapor generator means, condenser means coupled to receive vapor generated by said vapor generator means, a vapor rectifier column coupled to and surmounting said vapor generator means, said vapor rectifier column receiving ascending vapor output from said vapor generator means, conduit means connecting said condenser means to an upper portion of said rectifier column, said conduit means conveying condensate from said condenser means as a reflux to said rectifier column, said condensate influencing the production of vapor in said rectifier column, reflux modulating means for controlling the flow of condensate through said conduit into said rectifier column, said reflux modulating means including sensing means for determining the temperature of vapor at said upper portion of said rectifier column and means responsive to said sensing means for modulating the instantaneous flow of condensate through said conduit in relation to the temperature of vapor at said upper portion of said rectifier column whereby vapor generated by said rectifier column has an optimum concentration.
