PROBLEM TO BE SOLVED: To provide a steam generator capable of effectively distributing the amount of water circulation in an individual pipeline or circuit. SOLUTION: The steam generator (1) used for heating by a high-temperature waste gas, in particular, has two or more water-steam circuits (2, 3, 31 and 34) and each of the water-steam circuits (2, 3, 31 and 34) has at least one evaporator device (4, 5, 33 or 36) absorbing heat from a heating medium. The water- steam circuits (2, 3, 31 and 34) have at least one water-steam drum (6) and a down comer conduit (7) in common and pipelines (9, 10, 32 and 35) of the individual water-steam circuits (2, 3, 31 and 34) come out from at least one branch part (8) located in the down comer conduit (7), and the down comer conduit (7) constitutes venturi nozzle devices (11 and 12) in the sphere of the branch part (8). At least one water-steam circuit is provided in the sphere of a diffuser outlet (39) of the venturi devices (11 and 12) and the pipelines (10, 32 and 35) are constituted as dynamic pressure pipes and raise the pressure of an operating medium of the circuits (3, 31 and 34). |
