Zusammenfassung:	Process for the concentration of diluted solutions of corrosive products and installation for their application, said corrosive products being preferably sulfuric or lucid phosphoric lucid, said process comprising a step of preconcentration of the solution and a concentration stage proper of the preconcentrated solution, characterized by introducing the preconcentrated solution into a tunnel in which said solution is carried out in a thin layer and in successive cascades, and by heating said solution, during its passage, by combustión of a gas phase mixture inside a high power material of irradiation, arranged in the vicinity of the tunnel.
