The evaporating installation comprises at least one evaporating tube bundle placed inside a casing through which the heating fluid, such as a gas, circulates. The tube bundle is in communication with a liquid-steam separating chamber positioned outside this casing. Each of these bundles of nearly vertical tubes comprises a lower water entrance header and an upper vapor exit header, each being individually connected to the separating chamber outside the casing. The flow in these tube bundles is induced by natural circulation. The lower water entrance headed is fed by a tube passing through the upper header and through a central tube of the bundle and reaching finally with its open end into the lower header. The outer diameter of this feed tube is smaller than the inner diameter of the central tube in order to form around the feed tube a skirt of evaporating fluid. (NPO)
