In a heat exchanger for heating furnaces, in particular for high-efficiency furnaces, devices are provided in the tubes for increasing the turbulence of the water flowing through the tubes (10) around which the hot flue gases circulate. These devices are preferably rods (18) installed coaxially in the tubes (10). These rods (18) can also be used as tie rods for connecting pieces (22) that connect adjacent tubes (10) outside the heating furnace wall (12). <IMAGE> |
