Abstract

1248572 Heating fluids electrically LAPORTE TITANIUM Ltd 4 Oct 1968 [11 Oct 1967] 46500/67 Heading F4 AN2A A fluid heater comprises one or more metal tubes 1 provided internally with metal fins or similar members 13 arranged to increase the area of contact with the fluid and being in contact with the tube wall, and the configuration of the tube and fins is such that the cross-sectional area of the flow path of the heating current therethrough increases in the direction of flow of the fluid through the heater. Each fin assembly 12 comprises eight fins 13 constructed in four pairs by longitudinal bending of strips 15, Fig. 4 (not shown), and welded at intervals to short tubular spacers 14. Each tube 1 has a second fin assembly 21 immediately downstream of its electrical connector 11 (which connector is water-cooled), to give an initial large cross-sectional area of flow path for current before it decreases suddenly to its minimum value, i.e. the area of tube wall alone, and then increases in a stepwise manner along the fin assembly 12. Heated fluid flows through inlet manifolds 9, one at each end of the heater, along the heated tubes 1 to a transversely extending common outlet conduit 3. The outlet conduit 3 and supply manifolds 9 are eathed in operation, and D.C. is supplied to the connectors 11. The tubes I are of a platinum/rhodium alloy, as is conduit 3, but the fin assemblies 12, 21 are preferably platinum. Tubes 1 are alternatively platinum/ruthenium or platinum/iridium. The fins have indents 20, Fig. 4 (not shown) at intervals to reduce thermal stresses resulting from differential expansion between the fins and the tube wall. The heater is in a thermally insulating enclosure 2 of refractory material to which heat is supplied, other than by radiation from the tubes, to reduce heat losses from the tubes. The heater is used in the manufacture of titanium dioxide by the vapour-phase oxidation of titanium tetrachloride, using the process and other apparatus of Specification 1171113, or for heating of the halides of silicon, aluminium or zirconium (excluding fluorides).
