Abstract (en)
A heat generator with triple-pass flue gas circulation comprising a flue (2), which constitutes the first flue gas pass and is connected, at its ends, respectively to a front tube plate (3), with which a burner is associable, and to a rear tube plate (4). There is also a tube nest (5), which forms the second pass, and there are tubes (6) that form the third flue gas pass. The flue (2) has, at the openings (10, 11) for connection to the tube plates (3, 4), a cross-section that is smaller than the median transverse cross-section of the flue (2) itself. <MATH>
