(492 launched, of ,which "36 vessels of a deadweight tonnage of 281,700 were de- Aivered. "The American'c International 'Shipbuilding Corp., operator of the Hog Asland. yard, states that heavy rains during July prevented a record of 50 THE MARINE REVIEW ships with a deadweight tonnage of 391,250. The yard's fitst ship, the QuISTCONCK, sailed from Norfolk, Va., Jan. 2, 1919, with a cargo of coal, and in the next seven months, Hog Island vessels have October, 1919 logged 225,000 miles and have carried upward of 400,000 tons of cargo to prac- tically every important portinthe world. The present contract for 110 A-type and 12 B-type vessels will be completed about Sept. 1, 1920. Modern Equipment to Burn Fuel Oil J IL fuel as a bunkering medium O 'recently has enlisted the at- tention of many _ shipbuilders in this country and abroad, who are investigating the merits of the system. Marine engineers have made rapid strides during the last few years in perfecting means for handling oil fuel in marine service. The accompanying illustrations show an oil fuel burning installation recently developed by J. poamivel White & Co. Ltd, Hast Cowes, Isle of Wight, builders of oil fuel installations, boilers, engines and vessels. The installation illustrated consists ofan oil fuel pump which keeps the oil under pressure, oil filters and strainers which prevent foreign mat- ter from entering the burners and a heater which keeps the oil in a liquid state to facilitate the spraying action at the burner. A duplicate system is generally provided for changing should either of the single units fail to func- tion. A fan is also provided in cases where the funnel is not sufficiently high to assure the perfect combustion of the fuel. It is pointed out that these installa- tions can be arranged to suit coal or wood fired boilers in use at present, or to suit watertube boilers burning oil exclusively or in conjunction with coal or wood fuel. A_ special case front is provided whereby the grate necessary for the change from oil to coal is quickly made.

The apparatus is said to be easily manipulated. The White Co. gives the following instructions for lighting up with cold fuel: "Before lighting the sprayers, the suction strainers and the delivery filters should be examined and cleaned if this is found to be necessary. One, two or three sprayers can be used in. lighting, according to the _ require- ments of the _ installation. Te] 3s pointed out that it is advisable to heat the cone beforehand. This is readily accomplished by inserting oily waste which is afterward ignited. Heating the cone prevents chilling of the spray which causes the oil to drip. "After the cone is hot, the scraper is placed in position between the cone and the brickwork to prevent any oil dripping between the casings during the first few minutes. The sprayer is then placed in the cold position, closed, and the hand oil pump started. The oil is pumped until a pressure of approximately 200 pounds to the square inch is reached after which the air doors to the cone are opened. "The master valve on the delivery. side of the pump is now opened ready for starting. A lighted torch is in- serted through the opening made for the sprayer, the torch being held on the stokehold side of the sprayer. Otherwise, it is pointed out, the cold spray might extinguish the torch. Then the sprayer is opened slowly in the cold position. If possible ar- rangements should be _ provided so that the fireman can see if the funnel is smoking or not. This is accom- plished through glass deck plates or holes through the uptakes. He can then adjust the sprayer to eliminate the smoke. After a minute or so the torch can be withdrawn and two or three minutes later the scraper. The fireman, however, must pay attention to the sprayer and continue to adjust the cold-lighting arrangement as nec- essary. This is. essential, due to the fact that the difference of expansion between the -body and 'the 'spindle of the sprayer has a tendency to close it. This adjustment is necessary until sufficient steam has been generated to heat the oil to 100 degrees Faht. "As soon.as a few pounds of steam
