FIELD: power industry.
SUBSTANCE: in steam generator (1) with enclosure wall, (2) forming gas duct (20), which is arranged in bottom area from evaporation pipes (6) gasproof welded together and in top area from overheating pipes (6') gasproof welded together, overheating pipes (6') are included after evaporation pipes (6) on the side of fluid through water segregating system. To ensure especially high adaptability of steam generator in start mode or low load mode at low expenses on manufacturing and installation, water segregating system (14) has multiple water segregating elements (30), each of them accordingly connected on the side of fluid after or, accordingly, before less than ten evaporation pipes (6), preferably, by one single evaporation pipe and/or less than ten overheating pipes (6'), preferably, by one single overheating pipe (6').
EFFECT: improving steam generator operation reliability.
