An evaporator is described comprising a plurality of double-walled vertical tubes parallelly arranged whereby the heating fluid circulates inside the amular spaces between the tubes, the evaporating fluid being inside the inner tubes and outside the outer tubes. The velocity of circulation is controlled independently in two independent circuits formed by the inside of the said inner tubes on the one hand and by the outside of the outer tubes on the other hand. This regulation is performed preferably by a controlled reduction of the circulation in the space outside the tubes. The heating fluid may be pressurized by heavy water or carbon dioxide. A vertical column in which the evaporating fluid is held at a constant level feeds at its base the two evaporator circuits. (NPO)
