摘要： The invention relates to a heat exchange device comprising a channel wall defining a flow channel with an inlet for receiving a gas flow. The device further comprises one or more heat exchange surfaces positioned inside the flow channel creating different parallel flow paths for the gas flow through the flow channel, at least one of the heat exchange surfaces embedding one or more flow paths for a fluid heat exchange medium. The one or more deflection elements are positioned inside the flow channel and are attached to the channel wall to deflect the gas flow away from the channel wall.

摘要： A method and a rapper device for cleaning a heat exchange surface in a pressure vessel. The rapper device comprises a striker rod which has one end contacting the heat exchange surface in the pressure vessel and one end projecting out of the pressure vessel via a passage opening. The rapper device also comprises an impacting device for impacting the projecting end of the striker rod. A section of the striker rod is slideably supported in a pressure chamber adjacent the passage opening. The pressure chamber is connected to a sealing gas supply maintaining the pressure in the pressure chamber at a higher level than the pressure in the pressure vessel. A bellows defines a pressure chamber around at least a section of the striker rod.
