摘要:
A single drum all-welded boiler system (10) is provided for a furnace (20) having a combustion chamber (22) and a convection pass (26) connected to the combustion chamber in a transition area (28), the system (10) comprising a superheater (60) in the transition area (28), an economiser (70) in the convection pass (26) and a boiler (72) between the superheater (60) and the economiser (70). The superheater (60) includes a plurality of vertically extending tubes arranged in aligned rows, and the system includes rapping means (100) for applying impacts to the superheater tubes, thereby freeing the tubes of undesirable combustion deposits.

摘要:
The invention relates to a steam generator, comprising a combustion chamber (1), a flue gas duct (10), and a boiler assembly (2). The boiler assembly (2) has a plurality of individual, identically designed steam boilers (3) for obtaining an appropriate amount of steam. The steam boilers have riser pipes (4) that are guided through the combustion chamber (1). The steam boilers (3) can optionally have a respective pipe array, which comprises at least the riser pipe (4), a steam discharge pipe (5), a down pipe (6), and a connecting pipe (7) that leads from the down pipe (6) to the riser pipe (4).
