Abstract

989,963. Forced flow steam boilers. BABCOCK & WILCOX CO. April 30, 1962 [May 3, 1961], No. 16405/62. Heading F4A. A heat exchanger utilizing a liquid metal, e.g. sodium, as the heating fluid comprises an upright cylindrical pressure vessel 11 divided by a tubular baffle 56 into an inner cylindrical space 60 and an outer annular space 62, which communicates at the lower end of the vessel with the space 60, and inlet means for supplying an inert gas to the upper regions of the spaces 60 and 62. As shown, Fig. 1, the baffle 56, of octagonal cross-section, is carried by the removable head 14 of a steam generator, while a larger tubular baffle 58, also of octagonal section, contacts the wall of the pressure vessel 11 to form thermal barrier spaces 64, Fig. 3. Feedwater enters a chamber 26 in the head 14 through an inlet 36, passes down through straight tubes 68, connected in parallel and located within the inner space 60, and then up through risers 70, located in the annular space 62, the water being vaporized and the resulting steam superheated in these risers which are arranged in rows 74 each of which is in the form of a platen of nested serpentine tubes (Fig. 2, not shown). The steam collects in an annular chamber 34 in the head 14 and passes through an outlet 38. To enable an equal flow through each of the pipes, which have different lengths, suitable orifice plates (not shown) may be fitted to the tube inlets in the chamber 26. Access openings 40 and 42 are provided for the chambers 26 and 34 respectively. The liquid metal is introduced through inlets 48 in the walls of the vessel 11 and flows round an annular trough 54, the vertical wall of which forms a weir over which the metal flows on to the risers 70, a uniform annular distribution being thus obtained. An outlet 50 in the base of the vessel is provided for the liquid metal, which latter is maintained to a level 84 so that the lower parts of the tubes containing the water being heated are submerged in liquid metal. Inert gas is supplied to space 60, 62 and 64, by multiple inlets 80A (Fig. 2, not shown), 80B and 80C respectively, to provide a cushion effect in the event of any violent reaction due to mixing of the heat exchange fluids, while relief diaphragm nozzles 82 provide means for relieving any sudden pressure build up.
