摘要:
A method of and an apparatus for supporting walls of the furnace of a thermal power boiler, in which the furnace is suspended to hang on a supporting plane of the upper portion of steel structures especially arranged for the purpose, and the walls, being formed of water tubes, are supported horizontally at least by buckstays positioned substantially perpendicular to the water tubes, and vertical pillars, located outside the buckstays, are attached to the ground or the foundations of the boiler building. At least two of the walls, located on opposite sides of the furnace are supported in such a way that loads directed perpendicularly to the walls are transferred by the vertical pillars to internal stresses of at least one rigid plane surrounding the boiler.
摘要:
A forced flow vapor generator wherein at least one of the upright boundary walls of the furnace has upper and lower portions formed of panels of upwardly extending laterally spaced tubes rigidly united throughout most of their length. Some of the panels of the upper and lower wall portions have segments thereof interlaced and coextensive with each other, the interlaced segments being rigidly united to transmit the load of the lower wall portion to the upper wall portion.
摘要:
A forced flow vapor generator wherein at least one of the upright boundary walls of the furnace has a lower and upper section formed of a first and second group of parallel flow tubes respectively, the tubes in each group being rigidly united throughout most of their lengths and having portions thereof interlaced and coextensive with each other, the interlaced portions being detached from one another for the most part. Provisions for interconnecting the tubes of the first and second groups including having inlet and outlet portions of the tubes bent out of the plane of the wall, the bent out portions being detached from one another for the most part.
