HEAT EXCHANGER

Patent ·
OSTI ID:4006854
A heat exchanger, preferably for a gas cooled nuclear reactor, has a vessel so constructed that the hot gas enters it by an entrance tube preferably at the bottom and leaves it by preferably lateral exit tubes fitted near the top. The said vessel may be cylindrical with its axis vertical and enclose a tube system through which boiling water circulates. This tube system has vertical header pipes extended by entrance and exit tubes mounted in the cover of the vessel. Between the cylindrical vessel wall and the said tube system a further cylindrical casing is arranged, closed at the bottom and forming an interspace in which water circulates, cooling the wall of the vessel, so that this latter system may be used as economizer. The said interspace is separated at the top from the remaining space enclosed by the vessel. The entrance for this interspace is preferably near the bottom, the exit near the gas exits of the vessel.
