STEAM GENERATOR Russian patent published in 1997 - IPC

FIELD: power plant engineering. SUBSTANCE: steam generator has cylindrical body 1 with heat exchanging units 8 supplied by distributing and assembling headers 9 and 10 correspondingly which are gathered in cells. Headers 9 and 10 are connected to inlet and outlet collectors 5 and 6 by pipe lines 11 and 12. Pipe lines 11 ends are fitted inside pipe lines 12 in every cells. Distributing headers 9 and 10 are placed in cells reciprocally parallel and it's axes are placed in transversal cross-section on ring curve concentric with respect to heat source carrier collector. Every unit 8 is made by even number of equal length flat helices which planes are oriented perpendicular to heated medium flow and asymmetric with respect to diametric plate including symmetry axis of cell. Every cell adjacent units 8 are turned relatively at 180 deg. EFFECT: more effective heat removing. 3 dwg
