<p>Each module has a narrow linear burner (1) arranged upwards at a side of the module end so that horizontal flames enter a short narrow front hearth (2) which has the burner height and a depth equal to maximum flame length. The first heat exchanger (3) has at least one row of one vertical tubes parallel to the burner, heating water before circulation, while a similar second exchanger (4) preheats the return water by being placed in the fume exit collector (5). Hearth condensation water is evacuated at the base (61) and modules can be placed adjacently with all burners on the same side.</p> |
