Liquid containing liquid or solid components to be separated therefrom by evaporation of the liquid passes under pressure through a conically coiled pipe 1 and is heated by gas flowing countercurrently through the space within a sleeve 2 containing the coil, the Vapour formed together with the separated components and any unevaporated liquid flows through pipe outlet 8 into a combustion chamber 6 where the vapour rides through outlet 9 and the separated components and remaining liquid are removed through outlet 11. A flame tube 4 heats the gas flowing through sleeve 5 to the space surrounding the coil, the tube also heating the chamber to lessen condensation. Any condensate formed may be collected between a funnel placed within the chamber base and the chamber wall (Fig. 2 not shown). The vapours pass to a heat exchanger 18 (Fig. 3 not shown) to preheat the liquid, the condensate formed being drawn off. In the case of sea water being evaporated this condensate is fresh water, and the sea water passes to a vacuum evaporator 36 (Fig. 4 not shown) for partial evaporation before being fed to the coiled pipe. The vapours may be utilised to drive a motor 29.

Abstract: 1,159,811. Controlling burners. BABCOCK & WILCOX Ltd. 20 Oct., 1966 [21 Oct., 1965], No. 44699/65. Heading F4T. [Also in Divisions G1 and H3] A silicon photo-diode views a flickering burner flame and provides an output voltage which is proportional to the logarithm of the flame radiation, the alternating component of which indicates the ratio of the flicker component of the radiation illuminating the photo-diode to the average value thereof and thereby the efficiency of the burner. The average value of the photo-diode output is obtained to provide a measure of the average value of the radiation illuminating the photo-diode which may fall due to flame extinction or soiling of the sight glasses between the flame and the photodiode. In the burner to be monitored, shown in Fig. 1, pulverized coal and air pass along a tube 6 through a rotating diffuser 9 into the firing zone which is viewed by the silicon diode 121 positioned at the remote end of a sighting tube 22. Coaxial with the pipe 6 is an inner tube 15 carrying a retractable oil lighting-up burner 27. A further photo-cell 62 looking along the inner tube detects the presence or absence of pulverised coal in the delivery area.

The feedback amplifiers have low input impedance and thus there is no coupling between the two input impedances for the amplifier and thus no coupling between the two directions of transmission. By the operation of switches do 1-dc4, ds1, ds2 and contacts in CC the operator can, (a) speak to both parties, (b) speak only to one party or (c) monitor a call. In all cases the connection is made through CC by closing switches dc1-dc4 and opening switches ds1, ds2. (a) Speak to both parties: contacts g1, g2 and d1, d2 are closed to connect both lines through the amplifiers via transformers T1-T4. Shuntin resistors ra1-ra4 are used to match the operators set PO to the line impedance. (b) Speak to one party: contacts g1, g2 are operated to speak to party L1 leaving party L2 terminated on impedances Z1, Z2 through contacts d2, SU2 and d1, SU1 respectively. To speak to party L2, contacts d1, d2 are operated leaving line L 1 terminated on impedances Z 1, Z2.
