<p>The heat exchanger tube set is designed particularly for the fuel heat exchanger. The set comprises two heat exchange zones positioned one after another with respect to the combustion chamber (8), where zone one (1) is formed exclusively of tubes (3), and zone two (2) is composed of tubes (4) and finned elements (5) positioned in between the tubes (4). Preferably, the tubes (3) of zone one (1) are smooth, of any shape in cross-section, and the tubes (4) of zone two (2) are either flat or oval. Preferably, the finned element (5) consists of a band with profiled plates (6).</p> |
