FIELD: power engineering; manufacture of waste-heat boilers and heat exchangers. SUBSTANCE: water-tube boiler has shell with medium supply and discharge branch pipes and tube bundle located in shell and connected with central tube where downtake tube is mounted in spaced relation. Innovation of invention consists in that header with branch pipes passes through head of shell outside it; bottom of header located inside shell is connected with central tube and bottom located outside shell is connected with downtake tube; other end of tube bundle is connected with header. EFFECT: enhanced economical efficiency and reliability since header is used instead of tube sheet. |
