摘要： A fin (4, 4a, 4b, 4c, 4d) for a boiler tube arrangement comprising a number of boiler tubes (34, 36, 38, 40) extending along each other,and an assembly (32) comprising such a boiler tube arrangement and such a fin, are provided. Alongitudinal center axis (C) of the fin is arranged to extend perpendicular to a length of the boiler tubes, and the fin comprises an inner edge (8) and an outer edge (10). The fin ischaracterized in that a contour of the inner edge is similarto a contour of the outer edge. Each of the contours of the inner and outer edges definiesa number of ridges (16, 18, 20, 26, 28, 30) and a number of valleys (12, 14, 22, 24), which ridges and valleys are alternately arranged and connected to each other at transitions (P, P') being half way between a highest point (H, H') and a lowest point (L, L') of the connectedridge and valley, respectively.The valleys defined by the inner edge are each arranged to receive, and extend 180 degrees or less around a longitudinal center axis (A)of a respective one of the boiler tubes, to only partly enclose, saidrespective one of the boiler tubes.

摘要： A boiler and a method of operating a boiler are provided. The boiler (2, 56, 58, 62, 70, 112) comprises an exhaust gas inlet (26, 94, 130) for receiving exhaust gas (EG1), a first exhaust gas outlet (28, 96, 132) for discharging exhaust gas (EG1) and means (16, 18, 76, 114) for conveying exhaust gas (EG1) from said exhaust gas inlet (26, 94, 130) to said first exhaust gas outlet (28, 96, 132). The boiler further comprises a medium inlet (38, 90, 126) for receiving a medium, a medium outlet (40, 92, 128) for discharging the medium, and means (12, 82, 122) for conveying the medium from said medium inlet (38, 90, 126) to said medium outlet (40, 92, 128). The boiler is characterized in further comprising a bypass pipe (20, 88, 124) for conveying exhaust gas (EG1) from said exhaust gas inlet (26, 94, 130) to said first exhaust gas outlet (28, 96, 132), which bypass pipe (20, 88, 124) is enclosed by a circumferential wall (42, 98, 116) of the boiler (2, 56, 58, 62, 70, 112). A bypass regulator (44, 100, 134) is arranged to block or unblock the bypass pipe (20, 88, 124) to regulate an exhaust gas flow through the bypass pipe (20, 88, 124). A first pressure sensor (52, 108, 142) is arranged to measure a first exhaust gas pressure upstream the bypass pipe (20, 88, 124). A control unit (50, 106, 140) communicating with the first pressure sensor (52, 108, 142) and the bypass regulator (44, 100, 134) is arranged to control the bypass regulator (44, 100, 134) in dependence on said first pressure.
