The bars are omitted, and the furnace lined in fire-brick and the air is admitted through adjustable perforated gratings. The whole is shown in figs. 15, 16, 16a, 17, 18, 19, 19a. The same company have now four vessels so fitted. ig. 15. DIAGRAMMATIC ARRANGEMENT OF KÖRTING'S CENTRIFUGAL SPRAY APPARATUS FOR OIL BURNING The front of the oven is a disc of fire-brick with a small opening through which the spray is delivered and air is admitted. In this system the oil is made to spray itself and is claimed to be sufficiently atomized by the pressure and the action of the screwed needle round which it escapes. The general arrangement is as in fig., 15, and in figs. 16, 16a is shown the detail for a marine treble flue boiler, showing the two oil heaters in series on the suction and pressure sides of the pump. In fig. 17 is a design arranged by the Wallsend Slipway and Engineering Company for the Körting System, no brickwork in this case being built in the combustion chamber, but merely in the oven of the furnace. The furnace of ss. F. C. Laeisz is shown in fig. 18 with the furnace lining and the brickwork of the combustion chamber also. In fig. 19 the Körting sprayer is shown in section, and with its spirally wound needle which throws the oil into rapid rotation and causes it to spread widely at the nozzle, exactly as in the case of the Körting water cooling sprayers. The oil is first heated to 130°C. =266°F., according to Mr. Orde, and forced at a pressure of 50 pounds through the nozzles. It is con Fig. 16a. DETAIL ARRANGEMENT FOR MARINE BOILER.
