FIELD: applicable in production of condensers for steam turbines. ^ SUBSTANCE: the condenser of a steam turbine has a piping system, reducer with flat walls and a system of rods fastening these walls, and connecting the piping system to the turbine, headers with a cooling medium, connected to the inner cavities of the rods, are installed outside the walls of the reducer. Openings are made in the walls of the rods, they are positioned in the lower half of the circle of the rods (alteration 1). The condenser of the steam turbine has a piping system, reducer with flat walls and a system of rods fastening these walls, and connecting the piping system to the turbine. Vertical ribs are positioned on the rods, with cooling tube bunches installed in their holes, the bunches are connected through separate water chambers to the headers with a cooling medium, the water chambers and the headers with a cooling medium are positioned outside the walls of the reducer (alteration 2). ^ EFFECT: enhanced reliability and economical efficiency of the condenser due to elimination of excessive heating of the rigidity rods and reducer walls, prevention of buckling of the reducer and disturbance of leakproofness of the condenser steam space. ^ 3 cl, 6 dwg |
