摘要： A flue gas air preheater and a method for the installation of air pipes for a flue gas air preheater (3), wherein a set of air pipes (7) is connected to said preheater, the method comprising: cutting an air pipe (7) connected to the preheater and detaching the portion of the air pipe (7) that is to be removed from the preheater for replacement; fitting a separate new air pipe (7a) in place of the air pipe portion to be removed; and connecting said new air pipe (7a) to the remaining portion (7b) of the air pipe (7) in a sealed manner, as an extension of it. In an example, the fixing is performed utilizing a fastening sleeve (13) fixed to the end of the new air pipe (7a) and inserting it in the remaining portion (7b) of the air pipe (7). In an example, the fixing is performed by means of a mechanical sealing solution (13d, 13f) without welding. The air pipe component for the flue gas air preheater (3) comprises: an air pipe (7a), and a fastening sleeve (13).

摘要： A boiler comprising a flue gas duct and heat exchanger pipes (132, 212, 262) in the flue gas duct. The boiler comprises a planar silencer plate (320), which silencer plate (320) comprises sound absorbing material, and said first silencer plate (320) being placed downstream of one of said heat exchanger pipes (132, 212, 262) in the flow direction of flue gases in said flue gas duct. Furthermore, a silencer for a flue gas duct with a rectangular cross-section in a boiler, the silencer comprising at least a first and a second planar silencer plate (320) substantially parallel to the flow direction of flue gases, the silencer plates (320) comprising sound absorbing material. The first silencer plate is placed at an angle to the second silencer plate, wherein the width of the resonating area of the flue gas duct becomes narrower in two directions transverse to the flow direction of the flue gases.

摘要： An air nozzle arrangement (400) for a fluidized bed boiler (100), comprising an air feed pipe (410) and an air nozzle (420) which limit an air feed duct (430) configured to supply air to the furnace (106) of the fluidized bed boiler (100). The air nozzle arrangement (400) comprises a surface (450) configured to guide coarse material along said surface (450). At least part of said surface (450) is thermally insulated from the air nozzle (420) and/or the air feed pipe (410). Furthermore, at least part of said surface (450) is configured to protect at least part of said air nozzle (420) and/or air feed pipe (410). Thus, the temperature of said surface (450) is configured to be high when the fluidized bed boiler (100) is in operation, whereby the solidification of molten material of the fluidized bed in the air nozzle arrangement (400) is reduced.
