Lower Engine Room Port Side S.S. Dixie Looking Inboard—Main Condenser Circulating : Pump—Low Pressure First Reduction Gear lacing. The condenser, together with the condensing equipment, is designed to maintain 28% inches of vacuum with sea water at 65 degrees Fahr. The auxiliary condenser is similar to the main condenser with steel shell and cast steel flanged ends, and has 1600 square feet of cooling surface. The main condenser is fitted with two 2-stage C. H. Wheeler Co. radojet air ejectors fitted with interafter con- densers provided with automatic drain control. The auxiliary condenser is fitted with one C. H. Wheeler Co. radojet air ejector with after con- denser provided with automatic drain control. The radojets on the main condenser are independent and in du- plicate. There is also fitted in con- nection with the main condenser two vertical turbodriven condensate pumps arranged in duplicate. There are two main feed pumps of the vertical simplex valve pot type, 10% x 16 x 24 inches, capable of working against a pressure of 500 pounds per square inch. Also one auxiliary feed pump of the vertical duplex type, 7 x 12 x 12 inches. The fire and bilge pump is of the vertical duplex type, 12 x 7 x 12 inches. The ballast pump is of the vertical duplex type, 10 x 12 x 12 inches. There is one fresh water pump 7 x 8 x 12 S.S. Dixie—Lower Engine Room Starboard Side Looking Aft—Oil Strainers—Sanitary Pump—Bilge and Ballast Pumps 72 MARINE REVIEW—April, 1928 inches; one sanitary pump 10 x 12 x 12 inches; one evaporator feed pump 8% x 5% x 6 inches; one oil cooler circulating pump 10 x 12 x 12 inches; two oil fuel pumps 6 x 9 x 10 inches; one oil transfer pump 7% x 10% x 10 inches and two hot water pumps for furnishing hot water throughout the passenger accommodations. The feed water heater is of the paracoil type capable of raising the temperature of the feed water from 100 to 235 degrees when operating at full power. One thirty-ton evaporator is fitted, in connection with one 20,000- gallon distiller. The main circulating pump is of the centrifugal type with a normal ca- pacity of not less than 16,000 gallons per minute. The diameter of the suc- tion at discharge is 24 inches. It is operated by a single cylinder engine; the impeller is of brass and the shaft of Tobin bronze running in bronze bearings. Particularly careful attention was given to insulation on account of the high pressure and high temperature. All hot air ducts are insulated and all steam piping is double insulated with the insulation extending over all flanges and fittings on superheated lines. S.S. California's Speed It is interesting to note the num- ber of favorable comments that have been made on the operation of the Panama-Pacific liner, CALIFORNIA. P. A. §S. Franklin, president of the International Mercantile Marine Co., owner of the vessel, who made the voyage to San Francisco on her, said that the CALIFORNIA performed in a very satisfactory manner, that there was absolutely no vibration, which is an important factor for the com- fort of passengers, and that her fuel economy was even better than antici- pated. Representing the General Electric, Eskil Berg, marine engineer of that company, was also an interested ob- server of the performance of the vessel on her maiden voyage. He is reported to have said on his return, “The fuel economy and quietness of operation were above our expecta- tion. There was absolutely no noise or vibration from the propulsion ma- chinery. The ship was designed for 18 knots. On the outward run she averaged a little over 16% knots be- cause it was decided not to press the new machinery too much. On the return trip howevér, we did _ bet- ter. The 467 miles between Havana and Cape Hatteras were made at the rate of 19.7 knots or nearly two knots above the designed speed.”
