Abstract

151,258. Wilhelm, F. Sept. 19, 1919, [Convention date]. Concentric straight-tube apparatus.-In heatexchangers employing three concentric tubes, the outermost is made in sections to facilitate cleaning of the outer space. The two inner tubes a, b may ba welded at their ends, but the outermost is made in sections, two of which A, A, in the example shown in Fig. 1, are slightly smaller in diameter than the middle section B and connected at each joint by stuffing boxes f, f. The two parts comprising the middle section Bare united by a flange joint g. To take apart, the flange g is disconnected and each half of the section B is slid over the adjacent section A, and then each section A is slid towards the centre in turn. In a modification, the sections are of the same diameter tube, and each or any is divided longitudinally and united by flange joints. To prevent loss of heat at the ends, the device shown in Fig. 3 may be used comprising two stub tubes joined 'by a channel i to cover the ends of the tubes a and the connexion c, the whole being bolted to a supporting plate h and bearing flange connexions for the bends n.
