<p>Fired heat exchanger, in its top section having a combustion chamber (1) with an opening (2) for the insertion of the burner, and in its bottom section fitted with a condensate accumulation bowl (3) and vertical pipe elements (4) for the flow of fumes, which connect the combustion chamber (1) with the condensate accumulation bowl (3), fixed to the sieve bottoms (5, 6) of the jacket (7), inside which the heated fluid flows. The inlet stub pipe (8) and outlet stub pipe (9) are fitted in the lower sieve bottom (5) and end outside, which is achieved with the inlet connection stub pipe (10) and outlet connection stub pipe (1 1) integrally built into the flange (12) of the condensate accumulation bowl (3). The flange (12) is fitted with sockets (13) for the elements fixing the heat exchanger to the casing. Under the upper sieve bottom (6) there is a partition (16) fixed and fitted with at least one slot (17) for the flow of the fluid above the partition. There is a pipe (18) fixed to the partition (16) so as to drain the heated fluid from above the partition (16), connected to the fluid outlet stub pipe (9).</p> |
