HEAT EXCHANGER FOR THE RAPID COOLING OF FLUE GAS OF IRONWORK PLANTS, APPARATUS FOR THE TREATMENT OF FLUE GAS OF IRONWORK PLANTS COMPRISING SUCH A HEAT EXCHANGER AND RELATIVE TREATMENT METHOD

摘要

A heat exchanger rapid cooling flue gas of ironwork plants, including: a support structure of at least one module including an inlet manifold and an outlet manifold of the flue gas, mutually opposed and aligned; plural panels that extend between the inlet manifold and the outlet manifold mutually superimposed at a defined distance, pairs of adjacent panels defining flow channels of the flue gas closed laterally by shoulders and including at opposite ends respectively an inlet aperture communicating with the inlet manifold and an outlet aperture communicating with the outlet manifold; circulation ducts of a cooling fluid associated with the panels; and a first selective closing mechanism of the inlet apertures and a second selective closing mechanism of the outlet apertures of one or more of the channels; each of the channels laterally closed by a respective pair of shoulders of which at least one is of removable type.
