ae RS Re ee eC Tank Sounder and Draft Gage—Fire-Tube Superheater DEVICE for instantly indicating A the depth of water in any tank of a vessel and the draft has been developed by the Marine Electrical Co., Lorain, O. The indicator may be placed at any point on the ship, but it is usually used in the engine room and in the pilot house. By simply pressing the button corresponding to the tank which is to be sounded, the pointer indicates a figure on the dial of the instrument representing the number of feet of water in the tank. The device acts so quickly that it is claimed all of the tanks of a ship -may be sounded in less than a minute regardless of weather conditions. It is operated with alternating current, and therefore may be located in any part of the ship without danger of affecting the ship’s compass. Current is derived from a rotary converter operated from the ship’s dynamo or storage battery. First Marine Fire-Tube Superheater The fire-tube superheater has been ex- tensively applied in marine service by. European owners during the past six years with very gratifying results. In America, however, notwithstanding the fact that the superheater is well estab- lished both in industrial plants and in lccomotive service, about 15,000 super- heater locomotives now being in use, the first marine installation was made about three months ago. In fact the results obtained from the operation of over 200 superheater locomotives led to the in- stallation of a Schmidt high temper- ature fire-tube superheater by the ma- rine department of the Lehigh Valley railroad on its tug, WYOMING. WyomiInc is a vessel of 398 gross tons and has a towing capacity of 5,000 tons. She is 152 feet long, 27 feet 3 inches beam and has a draft of 16 feet and is propelled by a triple expansion engine with cylinders 17 inches, 25 inches and 43 inches in diameter by 30 inches stroke. Steam is furnished at 180 pounds pres- sure per square inch by a single Scotch boiler, to which is applied a fire-tube superheater furnished by the Locomotive Superheater Co., New York. The boiler has four furnaces and is 15 feet in diam- eter by 12 feet long over-all, the tube sheets being 8 feet 3 inches apart. It has a total evaporative heating surface of 2,926 square feet and a total grate area of 86.6 square feet. The super- heater has a heating surface of 758 co ey see Pooe ee : A Pes ee J TT OA) Mh: square feet and is made up of 80 units arranged in three groups. These groups are each made up of a saturated steam and a superheated steam header to which the ends of the units are secured. The groups are independent in their action, being separated from each other by valves which may be closed when de- sired. Two pyrometers are used to indicate the degree of superheat obtained, one of these instruments being located in the boiler room and the other just above the throttle in the engine room. The degree of superheat is governed by a mixing pipe, the superheated steam being cooled to any desired temperature by the ad- mission of saturated steam to the main steam pipe. The average superheat ob- TANK “SOUNDER AND DRAFT GAGE tained is about 185 degrees, the steam temperature averaging about 565 degrees Fahr., at 180 pounds pressure. Since the installation of the super- heater, Wyominc has been in daily ser- vice between Perth Amboy, N. y., and the New England coast hauling coal barges, some of which carry as much as 4,800 tons. During this time the coal has been weighed daily and care has been taken to secure reliable data on which to base conclusions as to the effect of the superheater. At the end of three months, Wyomnc is said to have shown a saving of over 15 per cent in fuel as compared with a similar period in the same service, prior to the application of the superheater. It has also been possible to keep the boat going con- stantly, thereby increasing the effective- 194 ZY Y y ZG ness of its operation in this 5 The results have been such that high Valley has announced its pl equip the other vessels of its rapidly as possible.
