1285859 Tubular heat exchangers J D B OSTBO 19 April 1971 [16 April 1970] 25986/71 Heading F4S A heat exchanger comprises a plurality of spirally wound tube elements 6 stacked one above the other within a cylindrical casing 3. As shown the stack is divided into three sections A, B and C. The elements in each section are connected to respective inlet and outlet headers 7, 8, 9, 10, 11, 12 which are located inside the casing but radially outside the stack; this arrangement permits a single faulty element 6 to be removed from the stack without disconnecting any other elements. Fluid supply to the particular section containing the faulty element is shut off thereby permitting the heat exchanger to be run at reduced capacity until the fault is repaired.
