FIELD: power engineering; generation of steam.
SUBSTANCE: parallel current flow steam generator has fencing wall formed of steam generator tubes, which tubes are pressure-tight welded together and are connected in parallel for letting fluid medium flow. At least some steam generator tubes are formed by many tube segments connected one to other in direction on side of fluid medium. Tube segments of vapor-generator tube, going one after other in direction of flowing fluid medium, are connected together through transition unit. Vapor-generating tubes are made of material, which has higher Vickers number than material used for manufacture of transition unit. According to method of production of parallel current flow steam generator, multiplicity of tube segments are connected in multiplicity of modules. Any module at multiplicity of sites of connection, provided for connection with next module, is provided with transition item correspondingly.
EFFECT: reduced technological costs.
