ENGINE ROOM CARFERRY KORSOR. AT LEFT—TOP VIEW OF MAIN ENGINES. The pumping plant is located at the back platform of the main engine alongside the wing tanks. Two dupli- cate tanks are fitted for the cooling water and lubricating oil services. Each of these plants are made up of an electric motor driving on the one side an 80-ton centrifugal pump for water supply, and on the other side a 60-ton geared wheel pump for lubri- cation. Two electric driven pumps of geared wheel type are used for hand- ling the fuel oil and two sets of elec- tric driven twin plunger type of pumps take care of the bilge and sanitary service. Heating and Auxiliary Boilers Aft of the main engine room in a separate boiler room there is installed two duplicate sets of so called com- bined boilers designed for a working pressure of about 100 pounds. These boilers are arranged for burning oil as well as the utilization of the ex- haust gases from the main engines and are used for heating all living quarters of the vessel and the rail- way cars on board. The boilers are of the water tube type and have an up- per and lower drum connected by vertical tubes. Before the exhaust gases are ad- mitted the boilers are thoroughly heat- ed by setting off the oil burners in order to prevent the formation of sul- phurie acid as a result of condensa- tion should the exhaust gases from the diesel engines come into contact with the cold surfaces inside the boiler. The oil burners are also intended to augment the exhaust gases in making steam during exceptionally cold pe- riods. During the warm periods of the year the exhaust gases are by passed and do not go through the boilers. The exhaust gases and the products of combustion of the oil burners are completely separated in these com- bined boilers to prevent a possible ex- plosion in changing over from exhaust gas to oil firing. The two boilers are connected by three pipes, for steam, hot and cold water respectively, and thus excellent circulation is obtained while raising steam. During the trial it was found that each boiler evap- orated about 1320 pounds of steam while the temperature of the gases were reduced about 480 degrees Fahr. in the boiler. The steam produced proved to be ample for all require- ments. The exhaust boiler acts at the. same time as a silencer and the ab- sence of noise was noticeable. The back pressure due to exhausting into the boilers was considerably reduced for the benefit of the power in the main engines. Living quarters are fitted on the Korsor for first, second and third class passengers. These quarters are AT RIGHT—AUXILIARY DIESEL ENGINES arranged on the promenade deck, the forward part of which affords perfect shelter as it is entirely enclosed and is fitted with large square windows. The sides and seats are neatly finished in light elm. The first class smoking room and restaurant are located centrally on the forward part of the promenade deck. These spaces are finished in dark polished mahogany and are fit- ted with comfortable chairs and lounges covered with leather. The first class dining room is reached by way of an entrance fitted with baggage racks and a hall finished in stained dark mahogany, through swinging doors with beveled plate glass. It is paneled in light polished birch inlaid with black. The galley is located aft of the dining room and is equipped with an oil fired range and perco- lators. There is also a pantry and pro- SPECIAL FERRY TYPE BURMEISTER & WAIN 8-CYLINDER, 4-CYCLE, SINGLE-ACTING DIESEL ENGINE ON TEST BED—TWO OF THESE ENGINES ARE INSTALLED IN THE CARFERRY KORSOR MARINE REVIEW—July, 1927 25
