FIELD: power engineering. ^ SUBSTANCE: in body 1, included in track 2 of superheated steam, there are pipes 3 of heating steam condensation. Pipes 3 are connected with their inlet ends to upper vertical chamber 4, and with their outlet ends - to lower vertical chamber 5. Lower chamber 5 of header 6 is arranged with vertical condensate collector 8, in which condensate level 9 is maintained. Condensate collector 8 is separated with a cross partition 10 into upper compartment 11 and lower compartment 12. Body 1 also hosts bundle of pipes 13 for condensate cooling, which are connected with their inlet ends to upper compartment 11 and with their outlet ends to lower compartment 12 of condensate collector 8. Such design of steam superheater makes it possible to use not only heat of heating steam condensation, but also heat of this steam condensate for steam superheating. ^ EFFECT: reduction of heating steam flow through steam superheater, higher flow of steam through turbine flow path, increased efficiency of turbine plant. ^ 2 cl, 3 dwg |
