In oil-tankers of Japan, it is very rare to have steam plants. “Kuroshio-Maru” which was recently completed has three main boilers of such a modern forced-circulating type as never been found formerly in our country. The steam condition of these boilers is 21 kg/cm2 G and 350°C. Each boiler generates steam 17, 000 kg/h at normal and 22, 000 kg/h at maximum. They are of the Kawasaki La-Mont marine water tube type and each has heating surface of 333 square metres excluding air-preheater, and is equipped with five oil burners, La-Mont water wall, superheater, economizer and tubular air-preheater. These boilers were adopted for the purpose to save space and to improve the.whole plant efficiency. One of these boilers was tested on land and obtained the efficiency of 87.29%.
