FIELD: heating systems.
SUBSTANCE: invention refers to power engineering and can be used at nuclear and thermal power stations. Steam-water heater consists of vertical housing 1 with tubular platens 2 which are longitudinally installed around vertical heated water header. Tubular platens 2 are enclosed with casing 5 which is partially filled with condensate thus forming cooling zone thereof. One inlet channel 9 and two outlet channels 10 of additional condensate are provided in the housing. Inlet channel 9 is connected to supply branch 11 of the additional condensate and to outlet channels 10. The latter are interconnected with condensate cooling zone by means of cross-over openings with water seal which are provided in the casing. Platens 2 are installed in bundles around vertical header thus forming the openings distributed around vertical header. Casing 5 is provided with vertical flutes 16 located in the openings between bundles of platens 2. Each channel 9 (10) of additional condensate is formed with the appropriate flute 16 of casing 5 and with baffle plates. Cross-over openings are provided in flute 16 of casing 5, which forms outlet channel 10 of additional condensate.
EFFECT: providing uniform distribution of additional condensate over condensate cooling zone.
