COOLED BOX OF HIGH-TEMPERATURE END SEAL IN STEAM-TURBINE CYLINDER

摘要

end seals for steam turbines. SUBSTANCE: proposed end-seal box has outlet hole and means for supplying high-temperature steam and mixing it up with leak steam. Mentioned means is made in the form of injector with nozzles disposed over box circumference; this injector is arranged on diametrically opposite side relative to outlet hole. Proposed design provides for optimal mixing of low-temperature steam with leak steam. EFFECT: improved uniformity of box cooling. 1 cl, 2 dwg
