The tube arrangement comprises four tubes (11-14) provided in the channel (2) for conveying the fluid. The tubes comprises a respective helical coil having a longitudinal center axis, a plurality of turns and a default pitch. A soot blowing device (30) comprises a first ejection pipe (31) having a plurality of nozzle openings (32) for ejecting a cleaning medium onto the tubes. The first intermediate ejection pipe is provided at an intermediate position in the helical coil of the tubes between two adjacent turns of the helical coil of the tubes.
