Abstract
SINCE the inception of the Kyushu Hydro-Electric Railway Co. Ltd. about twenty years ago, the policy of using steam power in Japan as distinct from hydro-electric power has thoroughly justified itself. A description is given of their new 50,000 kilowatt steam generating station, in the Metropolitan Vickers Gazette for October. It was completed in September 1931 having taken little more than a year to construct. The total cost of this station is much lower for its output than any station previously built in Japan. The main buildings are heavy steel structures designed with a view of resisting earthquakes and the walls of the building are of corrugated sheet steel. The chief coal supply is transported by land, the power station being quite close to the main railway line. Special arrangements have been made to minimise the labour and time involved in handling coal. The flue gases are thoroughly cleansed before emission into the air. The larger particles of grit are caught in mechanical collectors and the fine dust and fumes are washed by high-pressure water sprays. The molten slag is tapped from the furnaces, broken into fine pieces by strong water jets, and removed by pump sluicing. The two steam turbine generating sets having outputs of 25,000 kw. at 11,000 volts were made by the Metropolitan-Vickers Electrical Co. Ltd. Electroflo steam instruments are used and Kent, Negretti, Siemens, Kelvin, Cambridge and Bailey boiler instruments have been installed. It is interesting to notice that power is transmitted to a substation at 22,000 volts by cables of the Emanueli oil-filled type, paper insulated with a double sheathing of lead.
