Abstract
A method for uniformly distributing the vapor conducted from a parallel flow condenser section of an air cooled condenser into the dephlegmator cubes of a subsequently arranged countercurrent condenser includes throttling gaseous fluids present at the ends of the dephlegmator tubes on the collector side when the gaseous fluids are withdrawn from the dephlegmator tubes. In the air cooled condenser for carrying out the method, at least the predominant majority of the dephlegmator tubes has resistance elements at or near where they connect to the gas collector.
Claims11
A method for uniformly distributing vapor conducted from a parallel flow condenser of an air cooled condenser into dephlegmator tubes of a countercurrent condenser arranged downstream of the parallel flow condenser, wherein the dephlegmator tubes have ends at a collector side, the method comprising throttling gaseous fluids present at the ends of the dephlegmator tubes near the collector when the gaseous fluids are withdrawn from the dephlegmator tubes.
An air cooled direct condenser comprising at least one parallel flow condenser and at least one countercurrent condenser arranged downstream of the parallel flow condenser, the countercurrent condenser having a lower vapor distribution chamber, an upper gas collector and a plurality of dephlegmator tubes connecting the lower vapor distributing chamber and the upper gas collector, wherein the dephlegmator tubes have ends connecting to the gas collector, and wherein at least a predominant majority of the dephlegmator tubes have resistance elements for throttling flow of vapor from the dephlegmator tubes into the upper gas collector, the resistance elements being mounted at or near the ends of the dephlegmator tubes facing the upper gas collector.
