Abstract (en)
[origin: EP1213557A2] The invention relates to a tube structure, a flow channel structure and a heat exchanger, as well as their use, particularly in pre-heaters for air in boiler plants. The tube structure (P) is intended to be fixed between opposite walls (1, 2) of a flow channel (VK) or the like for a first heat transfer medium (VK) of a heat exchanger. A second heat transfer medium (TV) is arranged to flow through the tube structure (P). The tube structure (P) comprises, at its both ends (3, 4), fixing means (5, 6) for fixing the tube structure (P) in a releasable manner to the walls (1, 2) of the flow channel (VK). The first and second walls (1, 2) of the flow channel structure are provided with a compatible pair (17, 18) of holes, through which the tube structures (P) to be inserted in the heat exchanger are installed.
