<p>A modular apparatus (1) for the recovery of heat and for the purification of fumes coming from a boiler is described, said apparatus (1) comprising an inlet (5) adapted to receive the outlet fumes from the boiler, a heat exchanger module (2), a fume purification module (3) and an outlet (13) connected to a flue. The fume purification module (3) has an inlet (30) connected downstream of the horizontal heat exchanger (2) and an outlet coincident with the outlet (13) of the apparatus, said module (3) comprising a frame (20) with substantially "U"-shaped profile in turn comprising a baffle (11) adapted to divide said frame (20) into a first chamber (200) and into a second chamber (300), said first (200) and second (300) chambers being communicating by means of a passage (23) between the lower end of the baffle (11) and a bottom (19) of said frame (20) provided with drain (18). The heat exchanger module (2) comprises a plurality of plates (30) overlapped staggered with lying substantially parallel to the direction of motion of the fumes between adjacent plates (30), each plate (30) providing a chamber (31) for the motion of a heat- carrying fluid substantially counter-current with respect to the fumes.</p> |
