The radiant steam superheater for boilers, particularly for burning municipal refuse of the present invention, is situated in at least one radiant flue draught (2, 3) after a combustion chamber (1) as viewed in the direction of combustion products flow. The superheater comprises at least two vertical plate-like surfaces (6), performed from parallel tubes (7) in the form of at least two parallel-extending tubes, and these plate-like surfaces (6) have each at least one steam inlet (8, 9) and at least one steam outlet (10, 11), whereby the boiler is of the type having its individual flue draughts (2, 3, 4) are arranged in the direction of the boiler longitudinal axis (o), wherein the longitudinal axis (o) is common for all the flue draughts (2, 3, 4). The individual plate-like surfaces (6) of at least one radiant flue draught (2, 3) are series connected one after other with an alternately opposite direction of steam flow in such a manner that the outlet (10, 11) of one plate-like surface (6) is connected to the inlet (8, 9) of the next plate-like surface (6). These plate-like surfaces (6) are arranged in at least one row (601, 602), in which at least one plate-like surface (6) has an upper steam inlet (8) and at least one lower steam outlet (10), at least one other plate-like surface (6) has at least one lower steam inlet (9) and an upper steam outlet (11), at least one plate-like surface (6) is provided with a steam supply (12), and at least one other plate-like surface (6) is provided with a steam discharge (13). |
